Women, Elderly and Rural Americans More Likely to Have Chronic Pain

By Crystal Lindell

American women are more likely than men to experience chronic pain and high-impact pain severe enough to disrupt their lives. Americans of both sexes are also more likely to have pain if they live in rural areas, are over age 65, and of American Indian or Alaska Native descent. 

Those are the findings in a new report from the Centers for Disease Control and Prevention, which found that 24.3% of U.S. adults (60 million people) experienced chronic pain in 2023, while 8.5% (21 million) experienced high-impact pain that limited their daily life and work activities. 

What the report doesn’t tell you is that pain rates have risen dramatically since 2016, the year the CDC introduced its controversial opioid prescribing guideline, which drastically reduced patient access to opioids. Not only has the guideline failed to reduce overdoses, it appears to have worsened pain care for millions of Americans.

In 2016, the National Health Interview Survey estimated that 20.4% (50.0 million) of U.S. adults had chronic pain, while 8% (19.6 million) had high-impact chronic pain. What that essentially means is that 10 million more Americans have chronic pain today than in 2016, and 1.4 million more people have debilitating pain.

The CDC report does not speculate about why pain rates have increased, but a recent study that looked at the same survey data offers some insight, suggesting the increase is due to a number of factors, such as long Covid, more sedentary lifestyles, more anxiety and stress, and reduced access to healthcare.

“The widely-cited 20% prevalence of CP (chronic pain) in the adult US population appears obsolete,” wrote co-authors Anna Zajacova, PhD, and Hanna Grol-Prokopczyk, PhD, in medRxiv. “Our findings indicated that chronic pain, already a widespread issue, has reached new heights in the post-pandemic era, necessitating urgent attention and intervention strategies to address and alleviate this growing health crisis.”

While the CDC report neglects to cover the causes of pain, it does provide a detailed look at chronic pain rates by sex, race, age, and location.  For example, researchers found that people aged 65 and older are three times more likely to have chronic pain than young adults, while Whites are more likely to have pain than Blacks, Hispanics and Asians.

Chronic and High-Impact Pain by Sex:

• Women: 25.4% and 9.6%

• Men: 23.2% and 7.3%

Chronic and High-Impact Pain by Age:

• Ages 18–29: 12.3% and 3.0%

• Ages 30–44: 18.3% and 4.9%

• Ages 45–64: 28.7% and 11.3%

• Ages 65 and older: 36% and 13.5%

Chronic and High-Impact Pain by Race: 

• American Indian and Alaska Native: 30.7% and 12.7%

• White: 28% and 9.5%

• Black: 21.7% and 8.7%

• Hispanic: 17.1% and 6.5%

• Asian: 11.8% and 2.6%

Whether you live in a city, suburb or rural area also affects pain rates, with rural Americans significantly more likely to have chronic pain than those who live in cities. In the CDC study, large metropolitan areas of one million or more people are categorized as “central” or “fringe” counties. Medium and small metropolitan areas are counties with 250,000–999,999 people or less than 250,000 people, respectively. Non-metropolitan areas are rural counties with significantly fewer people.

Chronic Pain by Urban Area:

• Large central metropolitan area: 20.5% 

• Large fringe metropolitan area: 22.5%

• Medium and small metropolitan area: 26.4% 

• Non-metropolitan area: 31.4%

The CDC does not address the impact of chronic pain in its bare-bones report. But independent researchers Anna Zajacova and Hanna Grol-Prokopczyk do in their analysis, pointing out that pain “profoundly impacts” physical, mental and cognitive health, as well as employment, relationships, sexual function and sleep. It all adds up to an economic impact of $560-$635 billion annually — more than any other health condition.

“The findings are a call to action for public health professionals, policymakers, and researchers to further investigate the root causes of this increase. Addressing the rise in chronic pain is critical, as pain serves as a sensitive barometer of population health and has profound economic, social, and health consequences,” they wrote.

Unnecessary Back Surgeries Performed Every 8 Minutes at U.S. Hospitals

By Pat Anson

Over 200,000 unnecessary or “low value” back surgeries have been performed on older patients at U.S. hospitals over the last three years, about one procedure every eight minutes, according to a new report.

The analysis by the Lown Institute estimates the potential cost to Medicare at $2 billion for unnecessary spinal fusions, laminectomies and vertebroplasties. The procedures either fuse vertebrae together, remove part of a vertebra (laminectomy), or inject bone-like cement into fractured vertebrae (vertebroplasty) to stabilize them.

Lown maintains that fusions and laminectomies have little or no benefit for low-back pain caused by aging, while patients with spinal fractures caused by osteoporosis receive little benefit from vertebroplasties.

“We trust that our doctors make decisions based on the best available evidence, but that’s not always the case,” said Vikas Saini, MD, president of the Lown Institute, an independent think tank that analyzed Medicare and Medicare Advantage claims from 2019 to 2022.  

“In spinal surgery, as with other fields of medicine, physicians routinely overlook evidence to make exceptions, sometimes at shockingly high rates. This type of waste in Medicare is costly, both in terms of spending, and in risk to patients.”

Up to 30 million Americans receive medical care for spine problems each year. While surgery is appropriate for some, the Lown Institute considers many common surgeries overused and of low value to patients. Potential risks include infection, blood clots, stroke, heart and lung problems, paralysis and even death.

Spinal fusions and laminectomies are considered useful for patients who have low back pain caused by trauma, herniated discs, discitis, spondylosis, myelopathy, radiculopathy and scoliosis. Fusions are also appropriate for patients with spinal stenosis from neural claudication and spondylolisthesis; and laminectomies are appropriate for patients with stenosis who have neural claudication.

Wide Variation in Overuse Rates

Nationwide, about 14% of spinal fusions/laminectomies met the criteria for overuse, while 11% of surgery patients with osteoporosis received an unnecessary vertebroplasty.  

The Lown Institute found a wide variation in overuse rates at some of the nation’s largest and most prestigious hospitals. UC San Diego, for example, had a 1.2% overuse rate for fusions and laminectomies; while the Hospital of the University of Pennsylvania had a 32.6% overuse rate.

The largest overuse rate was at Mt. Nittany Medical Center in Pennsylvania, where nearly two-thirds (62.8%) of the fusions and laminectomies were considered inappropriate or of low value.

The Lown report found that over 3,400 doctors performed a high number of low-value back surgeries. Those physicians received a total of $64 million from device and drug companies for consulting, speaking fees, meals and travel, according to Open Payments. Three companies — Nuvasive, Medtronic and Stryker — paid over $22 million to doctors who performed the unnecessary surgeries.

Previous reports by the Lown Institute have also questioned the value of procedures such as knee arthroscopies, a type of “keyhole” surgery in which a small incision is made in the knee to repair ligaments. Research has found that arthroscopic surgeries provide only temporary relief from knee pain and do not improve function long-term.

The American Hospital Association takes a dim view of Lown studies, calling the data cherry-picked and misleading.

The 'Nocebo Effect’ and Irritable Bowel Syndrome

By Dr. Caroline Seiler

Many people find that wheat or gluten cause them to react in some way: Some people have a wheat allergy, some have the autoimmune condition celiac disease, but the majority find they have some sort of intolerance or sensitivity to wheat and gluten.

This is challenging to diagnose because there still aren’t any reliable biomarkers to confirm gluten or wheat sensitivity, and clinicians typically rely on patient self-reports.

In irritable bowel syndrome (IBS), patients experience gastrointestinal symptoms without any visible damage to the digestive tract. Many patients with IBS believe that specific foods, like gluten or wheat, trigger their symptoms, prompting them to exclude these foods from their diets without consulting a dietitian or their doctor.

Unsurprisingly, about a third of IBS patients develop disordered eating habits and perceptions about food that may cause symptoms in and of themselves, such as orthorexia, or an unhealthy preoccupation with healthy eating. This may cause a “nocebo effect,” where patients experience symptoms due to their beliefs and expectations about a substance they assume is causing their issues but is actually inert — a “nocebo.”

As a nutrition researcher at McMaster University’s Farncombe Institute, I’m a member of a team that ran a clinical trial to find out whether wheat, gluten or a gluten-free nocebo caused symptoms in IBS. And the results were surprising: even though some patients experienced worse symptoms from gluten or wheat, they weren’t very different from the nocebo, with similar proportions of patients reacting to each.

These results are similar to other published studies. Identifying the true sensitivities for patients with IBS is a controversial research area, with some studies finding gluten avoidance to be beneficial versus others finding it to have no significant effect.

Researchers from the United Kingdom and the Netherlands published an innovative study from the Lancet medical journal. Patients with reported gluten sensitivity were divided into four groups: Two groups were given gluten-free bread, but one of these groups was told it contained gluten and one was told it didn’t. Two other groups were given bread that did contain gluten, with one group believing it was gluten-free and the other believing it contained gluten.

The results showed that the patients who ate gluten and were also told they were eating gluten had significantly worse symptoms than the other three groups.

Gluten Misinformation

Given the controversial evidence that not only gluten, but other wheat components like fermentable carbohydrates or immune-stimulating proteins, may exacerbate IBS symptoms, it’s possible for this hot topic to get blown out of proportion or taken out of context, contributing to nutrition misinformation.

All of these factors — that it is often diagnosed by excluding all other options, the significant psychological component, the division in the scientific community and clinicians who often discount patients’ experiences — make treatment difficult for patients with this disorder.

As a result, patients with IBS are often left to navigate conflicting online resources and test new diets to treat their symptoms. When researchers challenge patients with gluten, wheat or a nocebo, they rarely report the personalized results back to the patients and see how this information impacts patient behaviour.

At McMaster University, we wanted to see how presenting personalized nutrition information would affect our patients. After providing them with personal results about their gluten and wheat reactions, we followed up with patients after six months or more to see how this impacted their beliefs, behaviours and symptoms.

Again, we were in for a surprise! Patients largely kept similar beliefs about gluten, maintained a gluten-free diet and had consistent symptoms even after learning that most of them did not react to gluten or wheat. This begs the question: when people more generally learn new information that conflicts with an existing belief, what may help them to change accordingly?

Psychological Treatment

IBS has been long understood as a disorder of the gut-brain interaction. Psychological treatments are being increasingly investigated to minimize patient fears of foods, or nocebo effects, and to treat IBS symptoms more generally. At Harvard, a recent study found that exposure-based cognitive behavioural therapy (CBT) showed promise to improve IBS symptoms in five sessions with a nurse practitioner.

Similarly, CBT correlated with shifts in brain networks and the gut microbiome, or gut bacteria, that were also correlated with improvements in gastrointestinal symptoms. At the University of Calgary, virtually delivered yoga was highly feasible and helped improve symptoms for patients with IBS.

However, IBS is a complex disorder which may be exacerbated due to many different causes, and psychological treatment will likely be only one component of an effective treatment plan for many patients.

Diet plays an important role in human health, but how it does so — especially among those with gastrointestinal diseases — becomes complicated by the emotional aspects of eating and the real needs for people to have nutritious, well-balanced diets without risking malnutrition. If you have concerns that certain foods, like gluten, trigger your symptoms, it’s a good idea to consult your doctor or a registered dietitian.

More Americans Have Chronic Pain Than Ever Before

By Pat Anson

Rates of chronic pain and high-impact pain have risen sharply in the United States since the start of the COVID-19 pandemic, which is likely due to an increase in sedentary lifestyles, anxiety and reduced access to healthcare.

In a study preprinted in medRxiv, researchers estimate that 60 million Americans in 2023 had chronic pain, up from 50 million in 2019. The study is based on results from 2019, 2021 and 2023 National Health Interview Surveys (NHIS) of a nationally representative sample of about 88,500 U.S. adults.

Caution is warranted when research is preprinted before undergoing peer-review, but the findings here are startling. Rates of chronic pain (CP) rose from 20.6% in 2019 (before the pandemic), to 20.9% in 2021, and surged to 24.3% in 2023.

High impact chronic pain (HICP), which is pain strong enough to limit daily life and work activity, rose from 7.5% of adults in 2019 to 8.5% in 2023. That translates to 21 million Americans living with debilitating pain.

“Chronic pain and high-impact chronic pain surged dramatically after the COVID pandemic. The widely-cited 20% prevalence of CP in the adult US population appears obsolete,” wrote co-authors Anna Zajacova, PhD, at Western University in Ontario and Hanna Grol-Prokopczyk, PhD, at the University of Buffalo.

“Our findings indicated that chronic pain, already a widespread issue, has reached new heights in the post-pandemic era, necessitating urgent attention and intervention strategies to address and alleviate this growing health crisis.”

The increases in pain occurred in almost all body areas, such as the head, abdomen, back, arms, hands, hips, knees and feet, except for jaw and dental pain. All age groups and both sexes were affected.  

SOURCE: medRxiv

Researchers say being infected with COVID or having long COVID played a significant role in the increases, but social and economic causes may have also been at work. Pain could have worsened due to anxiety, depression, loneliness, physical inactivity and reduced access to health care, as well as inflation and economic hardships caused by the pandemic.

“The 2023 surge is not restricted to specific demographics or body sites — it is widespread across the population subgroups and affects all examined pain sites except jaw/dental pain. Further, the increase persisted even after accounting for potential drivers such as COVID-19 infections, socioeconomic factors, and other potentially important covariates such as mental health or health behaviors. This suggests that a broader, more complex set of factors may be at play,” researchers reported.

“Thus, while the viral infections certainly had an impact, other societal and lifestyle changes that occurred during and after the pandemic may have contributed to the increase in pain. The role of increased social isolation and loneliness, disrupted health care access, and heightened levels of stress and anxiety, all of which were exacerbated by the pandemic, should be explored in future research.”

Although chronic pain rates have surged over the last few years, there has been little response from healthcare providers and regulators. In fact, the just opposite happening. The Food and Drug Administration predicted a 7.9% decline in medical need for opioid pain medication in 2024, and anticipates a 6.6% decrease in demand next year.

The Drug Enforcement Administration uses those FDA estimates when setting its annual production quotas for opioids, which have fallen for eight straight years. Since 2015, the supply of oxycodone has been reduced by over 68% and hydrocodone by nearly 73%.

Many pain patients feel like they’ve been abandoned by the healthcare system, according to a 2023 PNN survey of nearly 3,000 patients or caregivers. About one in five patients have been unable to find a doctor to treat their pain, and 12% say they were abandoned or discharged by a doctor. Many are now hoarding opioid medication or turning to other substances for relief.

Those findings from our survey are now being reflected in the study on rising pain rates.

“The findings are a call to action for public health professionals, policymakers, and researchers to further investigate the root causes of this increase. Addressing the rise in chronic pain is critical, as pain serves as a sensitive barometer of population health and has profound economic, social, and health consequences,” said Zajacova and Hanna Grol-Prokopczyk.

Women with Endometriosis Often Miss School and Work Due to Pain

By Dr. Rasha Al-Lami

More than two-thirds of women with endometriosis missed school or work due to pain from the condition, in a study of more than 17,000 women between the ages of 15 and 44 in the U.S. That is a key finding of new research published in the Journal of Endometriosis and Uterine Disorders.

Our study also found that Black and Hispanic women were less likely to be diagnosed with endometriosis compared with white women. Interestingly, women who identified as part of the LGBTQ community had a higher likelihood of receiving an endometriosis diagnosis than heterosexual women.

We used data from the National Health and Nutrition Examination Survey, which is administered by the Centers for Disease Control and Prevention, for the period 2011 to 2019. The survey data use adjusted weights to account for the racial composition of U.S. society, meaning our sample of 17,619 women represents 51,981,323 women of the U.S. population.

We specifically examined factors related to quality of life, such as poverty, education and functional impairment, as well as race and sexual orientation.

Endometriosis is a chronic, often painful condition that affects approximately 10% of reproductive-age women worldwide. It occurs when tissues that would normally line the inner surface of the uterus instead occur outside the uterus, such as on the ovaries or even in distant organs such as the lungs or brain. These abnormally located lesions respond to hormonal changes during the menstrual cycle, causing pain when stimulated by the hormones that regulate the menstrual cycle.

Black and Hispanic Women Less Likely to Be Diagnosed

Our study sheds light on how endometriosis, despite its prevalence, remains underdiagnosed and underresearched. We found that 6.4% of reproductive-age women in the U.S. had an endometriosis diagnosis. More than 67% reported missed work or school, or having been unable to perform daily activities, due to pain associated with endometriosis.

Our study highlights disparities in the diagnosis and management of endometriosis among different racial groups. Black women had 63% lower odds of getting an endometriosis diagnosis, and Hispanic women had 55% lower odds compared with non-Hispanic white women. This disparity may reflect historical biases in health care, pointing to the need for more equitable practices.

In addition, our study underscores the importance of considering women’s health across diverse population subgroups, with particular attention to sexual orientation. We found that non-heterosexual lesbian, gay, bisexual, transgender and queer women had 54% higher odds of receiving an endometriosis diagnosis compared with straight women. Our study was the first to examine endometriosis likelihood among non-heterosexual women at the national level in the U.S.

We found no significant association between endometriosis and other quality-of-life indicators such as poverty, education or employment status, which suggests that the condition affects women across various socioeconomic backgrounds.

Our work adds to the growing body of evidence that Black women are less likely to be diagnosed with endometriosis and that their reported pain symptoms are often overlooked.

Explanations for this inequity include health care bias against minority women and limited access to medical care among Black women. Research also shows that many medical professionals as well as medical students and residents believe that Black women have a lower pain threshold compared with the white population.

This is another possible reason that pain symptoms among Black women with endometriosis get neglected. Researchers from the U.K reported the same findings, attributing these disparities to systemic bias and inequitable medical care.

Another study estimates that the lifetime costs associated with having endometriosis are about $27,855 per year per patient in the U.S., costing the country about $22 billion annually on health care expenditures.

How to Inhibit Reactivation of the Epstein-Barr Virus

By Dr. Forest Tennant

The Epstein-Barr virus (EBV) is a parasite that normally lives a dormant, harmless life in nasal and throat membranes and in our white blood cells. We are all carriers of EBV.

EBV usually enters the body and first activates during infancy, often resulting in a case of the "sniffles." In teenagers or young adults, it may trigger infectious mononucleosis. After the initial infection, the virus becomes dormant.

Unfortunately, EBV has the ability to reactivate, duplicate, and travel in the blood inside lymphocytes (white blood cells) to harm tissues and cause pain. How does this happen?

Biologic stress, meaning a physical or psychological situation that cause the hormones cortisol and adrenaline to elevate for more than a few hours, may lower one's immune system. That gives EBV the opportunity to reactivate, produce auto-antibodies, infiltrate tissue, and silently produce a painful condition.

The usual stressors that cause reactivation are physical trauma or injury, an infection, or emotional distress. People with medical conditions such as a genetic connective tissue disease (Ehlers-Danlos syndrome), diabetes, or stroke may have an immune deficiency that also makes them more prone to EBV reactivation.

EBV reactivation is similar to herpes or shingles reactivation. Like EBV, herpes and shingles are usually dormant and harmless viral infections, but they may reactivate and cause blisters or a skin rash.  

Unfortunately, EBV reactivation can be totally asymptomatic and unknown to the individual, until chronic reactivations cause a painful condition. This could result in fibromyalgia, small fiber neuropathy, burning mouth, herniated disc, arachnoiditis or even a cancer such as Hodgkin's disease or lymphoma. 

How to Diagnose and Treat EBV Reactivation

Persons with chronic pain severe enough to require daily pain relief medication may have EBV reactivation as a cause of their condition and should take steps to inhibit it. We recommend antibody testing for EBV reactivation in any person who has severe chronic pain for over 90 days and needs to take pain relievers daily.

Two antibodies are formed during EBV reactivation: the Viral Capsid Antibody (VCA) and Epstein-Barr Nuclear Antibody (EBNA).

Major laboratories offer three quantitative tests for VCA, EBNA and early EBNA antibodies. Qualitative tests (positive or negative) are not specific enough to make a diagnosis of EBV reactivation.

When VCA and EBNA antibodies are elevated above normal levels, a diagnosis of past reactivation is made, and the individual can properly be called a "chronic reactivator." We recommend that levels of VCA and EBNA be two or more times above normal, plus a patient having pain in two or more anatomic sites, to warrant a diagnosis of EBV reactivation.

If the early EBNA antibody is elevated above normal, therapeutic trials of antivirals and corticosteroids should be considered to reverse reactivation.

If both VCA and EBNA are elevated but the early EBNA is negative, we recommend the use of these vitamins and supplements to inhibit EBV reactivation:

• Vitamins C and D

• Astragalus

• Zinc

• Resveratrol

• Curcumin

• Selenium

• Luteolin

• Andrographis

• Lysine

Our research has found that about 90% of patients with adhesive arachnoiditis (AA) have EBV reactivation.  The good news is that once it is determined that a person has reactivation and autoimmunity, there are simple treatment measures that can be implemented.   

In our experience, the treatment measures tend to provide about 20% to 50% more pain relief when used with standard pain therapies. Failure to take therapeutic measures to control EBV may allow increased disease deterioration and pain. 

More information about the Epstein-Barr Virus and its relationship to chronic pain conditions can be found in our new book: "The Epstein-Barr Virus: A New Factor in the Care of Chronic Pain."

Racial Myths About Pain Are Embedded in Artificial Intelligence

By Crystal Lindell

A new study published in JAMA found that artificial intelligence (AI) programs are encoded with racial and ethnic biases – just like humans – when it comes to evaluating a patient's pain. 

The authors said they wanted to look into the issue because it's already well-known that doctors underestimate and undertreat black patients’ pain compared to white patients. 

To study how that may impact AI, researchers had 222 medical students and residents evaluate two different patients, one black and one white, who were both experiencing pain. They also had them evaluate statements about how race may impact biology, some of which were myths and some of which were true. 

Then the researchers had two Large Language Models (LLMs) widely used in AI — Gemini Pro  and GPT-4 — do the same by feeding them patient information reports, and then having them evaluate statements about how race impacts biology. 

There wasn’t much difference between the humans and the AI models when it came to rating patients’ pain, regardless of race. Both the humans and the AI models rated the patients as having similar pain scores. 

However, both the humans and AI systems had some false beliefs about race and patient pain. Gemini Pro fared the worst, while GPT-4 and the humans came out relatively similar. 

Specifically, Gemini Pro had the highest rate of racial myths (24%). That was followed by the humans (12%) and GPT-4 (9%).

“Although LLMs rate pain similarly between races and ethnicities, they underestimate pain among Black individuals in the presence of false beliefs,” wrote lead author Brototo Deb, MD, a resident at Georgetown University–MedStar Washington Hospital Center.

“Given LLMs’ significant abilities in assisting with clinical reasoning, as well as a human tendency toward automation bias, these biases could propagate race and ethnicity–based medicine and the undertreatment of pain in Black patients.”

Deb and co-author Adam Rodman, MD, says their study corresponds with previous research showing that AI models have biases related to race and ethnicity. 

Given how AI is increasingly used in clinical practice, there’s concern that black patients’ pain will continue to be undertreated, making them less likely to get opioids and more likely to be drug tested. 

There’s a common belief that AI will eliminate racial bias because computers are seen as more logical than humans. However, AI is encoded with data provided by humans, which means as long as humans have bias, AI will too. 

The real problem is if doctors start to rely too much on AI for patient evaluations, there’s a potential for real harm. Especially if doctors use AI to justify their medical decisions under the false belief that they are unbiased. 

It’s still unclear how these new AI systems will impact healthcare, but everyone involved should be careful to avoid relying too heavily on them. At the end of the day, just like the humans who program them, AI models have their flaws. 

Why Autumn Weather Is Often Miserable for Pain Patients

Intellectually, I love the concept of a crisp autumn day. I love the idea of pumpkin spice lattes, crockpot chili, and cozy scarfs. But in practice, the intense temperature swings are pretty horrible for me every year.

The cool fall weather here in Northern Illinois is always devastating on my body. Indeed, my chronic pain has been 10/10 the last few days as the temperatures start their yearly drop, and it rains non-stop. 

It’s the same with spring too. Regardless of how much I’m longing for warmer weather every March, the shift from winter to summer means I spend most of the spring in too much pain to function. 

To me, it is obvious that these weather changes impact my pain. I’ve been dealing with it for more than a decade now. And every year, spring and autumn are especially bad. 

Surprisingly, the medical community still questions whether or not the link between weather and pain is real though – and if it is real, why it might be happening. 

“Research still hasn't confirmed a cause-and-effect link between weather and joint pain, though many people insist they can predict the weather based on such aches,” writes Toni Golen, MD, Editor in Chief of Harvard Women's Health Watch, in a 2022 article in Harvard Health,  

A 2015 study looked at whether daily weather conditions and changes in the weather influenced joint pain in older people with osteoarthritis in six European countries.

While they did find a causal link, they hesitated to call it a direct cause, saying that “the associations between day-to-day weather changes and pain do not confirm causation.”

In other words, researchers did not want to say outright that changes in the weather directly causes pain spikes. 

So I guess you’ll have to hear it from me instead: As a chronic pain patient, I can confirm that the effect is real, and it’s not in your head. Weather definitely causes pain spikes.

What might be causing it though? Golen explains that one theory is that changes in barometric pressure — which often happen as the weather changes — trigger pain in the joints. 

“Less air pressure surrounding the body can allow muscles, tendons, and other tissues around joints to expand,” she explains. “This can place pressure on joints, possibly leading to pain.”

Another theory is that cold, damp days make you more likely to do things that can worsen joint pain or stiffness, such as sitting on the couch too long watching movies. 

“Also, since you're expecting discomfort when the weather shifts, you may notice joint aches more than you would otherwise,” Golen adds. “To ward off weather-related joint pain, keep moving with regular exercise and stretching.”

I have to say, the second theory reads as a bit insulting to me. It sounds like health professionals are trying to find another way to blame patients for their pain. 

Personally, I also know that being sedentary is not the cause of my increased pain when the weather changes. That’s partly because when I wake up with pain in the morning, trying to shower and get out of the house quickly is likely to aggravate it. Also, as someone who works from home, I spend most of my days sitting down with a laptop and that usually doesn’t cause my pain to spike.  

As a chronic patient, I also don’t need a study to confirm my experience. I know weather changes cause a pain spike for me, and over the years I’ve learned to cope with it by accepting it. My life is set up so that most of the time, on bad pain days, I have the ability to rest as needed. 

When I first started having daily chronic pain, I would get very stressed about pain spikes, which would make them worse and harder to get under control. But now I know that keeping myself as calm as possible is the key to riding it out. 

I also know that it’s very likely that the pain will start to subside to more manageable levels after a couple of days at the most. And I know to take advantage of my low-pain days to get as much done as possible. In fact, I’m using one this week to write this column.

To me, the link between weather changes and pain spikes is so obvious, that I can’t even believe any doctors would still question it. If you’re among those struggling as the seasons change though, just know, I believe you. 

Youths with Chronic Pain More Likely to Have Anxiety and Depression

By Crystal Lindell

Young people with chronic pain are more likely to suffer from anxiety and depression, according to new research published in JAMA Pediatrics.

Researchers in the U.S. and Australia reviewed 79 previous studies involving over 12,600 youths with chronic pain. The average age was about 14. Many live with chronic illnesses such as juvenile idiopathic arthritis, fibromyalgia, Crohn’s disease and colitis. 

The research team found that 34.6% had an anxiety disorder and 12.2% had depression. Those rates are more than 3 times higher than what is normally seen in a community setting.

Researchers say mental health screening, prevention and treatment should be a priority for young people with chronic pain. 

“A simple way to put this into practice would be for pain practitioners to consider a short screening assessment for symptoms of anxiety and depression in young patients,” said lead author Joanne Dudeney, PhD, a clinical psychologist and research fellow at Macquarie University in Australia.

“This is a vulnerable population, and if we’re not considering the mental health component, it’s likely we’re also not going to achieve the clinical improvements we want to see.”

The findings are surprising to me because I would have expected the rates of anxiety and depression to be even higher. Chronic pain is depressing, and it’s also natural that dealing with it would cause anxiety. Plus, the teenage years are infamous for being a hotbed of intense emotions – even for those who aren’t dealing with physical ailments. 

So if you had asked me to guess how many teens with chronic pain had depression and/or anxiety, I would have said something closer to 95 percent. It’s a wonder how anyone with chronic pain is not depressed or anxious. 

Regardless, I’m always glad to see more data like this, validating the experiences of those of us with chronic pain – especially when it comes to younger patients. Anyone who is more likely to suffer from mental health problems should be screened for them so they can get treatment.

Many doctors try to blame pain symptoms on depression and anxiety, so I always worry that research like this will somehow be used against patients. I could easily see doctors focusing on the mental health issues associated with chronic pain more than the physical ones after reading this study. 

The more hopeful scenario though is that this type of research is instead used to save lives and to make being alive easier for young pain patients. If more mental health screenings are able to prevent and treat depression, anxiety, and coping behaviors like self-harm, drug use and even suicidal ideation, that would be incredible. 

If you’re young and dealing with chronic pain, depression and/or anxiety, I want you to know that I am out here rooting for you. Your life matters in ways you can’t even fully grasp yet, and we need you to keep going. The world is a better place with you in it.

Study Finds Link Between Belly Fat and Chronic Pain, but Which Causes Which?

By Crystal Lindell

A new study shows a link between abdominal fat and chronic musculoskeletal pain, but even the authors admit that it’s unclear which one causes which. 

The study, published in the American Society for Regional Anesthesia & Pain Medicine, found that abdominal adipose tissue (fat) is associated with chronic pain in multiple sites and widespread chronic pain. It also found that women were at higher risk for this association than men. 

“Reducing abdominal adiposity may be considered a target for chronic pain management, particularly in those with pain in multiple sites and widespread pain," wrote lead author Feng Pan, PhD, Senior Research Fellow at the Menzies Institute for Medical Research in Australia. “The identified stronger effects in women than men may reflect sex differences in fat distribution and hormones.”

In layman's terms, they’re suggesting that chronic pain patients be told to lose weight. Especially if they are women.

However, further down in the study, while discussing its limitations, they admit that the research does not “address the issue of potential bidirectional causality.” In other words, they cannot say whether excess abdominal fat causes chronic pain, or whether chronic pain causes excess abdominal fat. 

The researchers looked at health data from 32,409 people taking part in the UK Biobank study, a large research study with half a million UK participants.

The study used MRI images to measure visceral adipose tissue (VAT), which is fat that surrounds the organs in the abdominal cavity, such as the liver, stomach and intestines. They also measured subcutaneous adipose tissue (SAT), the layer of fat that sits between the skin and muscles in the body. 

Participants were asked if they had pain in a specific area of their body or all over their body for more than three months. 

Two years later, all the assessments were carried out again in 638 people in the group.

The results showed that the more fat people carried around their abdomens, the higher their chance of reporting chronic musculoskeletal pain.

To weed out contributing factors, the researchers adjusted for many things, such as age, height, ethnicity, household income, education, alcohol frequency, smoking, physical activity, comorbid conditions, sleep duration, psychological problems and follow-up time.

While a specific link between abdominal fat and chronic pain may be new, the idea that fat could contribute to chronic pain by making people more sedentary and less likely to exercise has a long history.

However, as a patient who gained weight after developing chronic pain and being put on a number of medications that had weight gain listed as a side effect, I’m always extremely skeptical about which causes which. 

Especially because I gained and lost weight multiple times over the 11 years that I’ve been in pain, and have never noticed either one impacting my pain levels. 

In my experience, many doctors are quick to dismiss symptoms when they can blame a patient’s weight as the cause. Even when the excess weight was literally caused by medications they prescribed. 

Doctors use studies like these to blame pain patients for their problems, while absolving themselves of any responsibility to help. Patients are told their pain is their fault, and if they’d just lose weight, they’d feel better. 

Then, when losing weight proves predictably difficult, the doctor can throw up their hands at the whole situation and proclaim that the patient must not want to get better. In other words, doctors set an impossible standard for patients and then blame the patient when they fail to meet it. 

As new weight loss GLP-1 medications like Ozempic and related drugs become more popular, it will be interesting to see how they impact conversations about weight loss and chronic pain. If the medications are as good as they claim to be at helping people lose weight, we might finally get some large-scale research into how losing weight actually impacts pain levels. 

And if more patients are able to lose weight when their doctors tell them too, physicians may find that they have to do more than just tell their patients to “lose weight” when it comes to treating pain.

Deception Was Used to Get Patients to Participate in Opioid Study

By Pat Anson

“We are lying to you to see if you are lying to us.”

That’s how patient advocate Andrea Anderson sums up the Orwellian methodology behind a recent study that explored whether pain patients are taking their opioid medication appropriately.

The study made use of high-tech pill bottles that record in real-time how often a bottle is opened and any changes to its weight. The goal is to see if patients adhered to their opioid regimen or were taking too many pills at once – a possible sign of abuse or diversion.

Researchers at the University of Texas Medical Branch (UTMB) enrolled 28 chronic pain patients in the study, giving participants a 90-day supply of opioids in three 30-dose pill bottles. Eighteen patients were given pills in the high-tech bottles --- known as the medication event monitoring system (MEMS) --- while the other 10 were given standard pill bottles. Patients in both groups were asked to keep a daily diary of their medication use

Here’s where the lying comes in. Instead of telling participants that the MEMS bottles would keep track of pills being removed, patients were told that the temperature and humidity inside the bottles were being monitored.

“The study involved incomplete disclosure and deception, as participants were informed that the purpose of the study was to test a new prescription bottle that will monitor the physical environment inside the bottle…. Participants were not informed that the bottles would record the number and timing of pills dispensed,” wrote lead author David Houghton, PhD, an Assistant Professor of Psychiatry and Behavioral Sciences at the Center for Addiction Research at UTMB.

You might think that lying and deception would be prohibited in clinical trials, but the design of this study was approved by an ethics review panel at UTMB. Researchers say they also complied with international research guidelines that allow deception to be used in psychology studies “when there is no alternative method that will produce reliable and valid results.”

At first glance, the study findings suggest that many patients were less than honest about their opioid use.

“Participants who received MEMS demonstrated highly heterogenous dosing patterns, with a substantial number of patients rapidly removing excessive amounts of medication and/or ‘stockpiling’ medication,” researchers reported in the Journal of Pain Research.

“Several sharp decreases in medication supply over short time periods were observed, and a substantial portion of participants ran out of medication before 30 days had elapsed. These data could reflect over-consumption or diversion of medication.”

In addition, 25% of participants in the MEMS group tested negative for opioid metabolites in their urine drug tests, which suggests they may have been hoarding or selling their opioids, and not taking them.

‘Hypothetically Significant’

But the small size of the study – just 18 patients in the MEMS group – raises questions about the reliability of the findings.

Diversion of opioid medication is actually quite rare – about three-tenths of one percent of prescribed pills, according to the DEA.

It’s also not uncommon for patients to stockpile opioid medication. In a recent PNN survey of nearly 3,000 pain patients, 32% told us that they hoarded opioids, in many cases because they are worried about shortages or losing access to opioids in the future.

Although participants in the UTMB study were told to remove pills from their bottles just before taking them, it’s possible that they took out an extra amount simply to fill their weekly pill boxes.

Researchers were also surprised to find that some participants appeared to put pills back into the bottles, another sign that those “highly heterogenous dosing patterns” tell us little, if anything, about opioid use.

In other words, the study may be nothing more than a case of “garbage in, garbage out,” with any number of reasonable explanations for patient behavior.

“It is impossible to conclusively determine that aberrant behavior, as recorded by the MEMS system, reflects misuse or diversion,” researchers admitted.

“It’s a terrible study in every way, and should never have happened,” says Andrea Anderson, who sees obvious flaws in MEMS that make its data unreliable. 

“If you wanted to divert your tablets, you could just take out the proper amount every time the stupid bottlecap lets you. Once you collected 20 tablets, you could go sell them if you wanted or take however many you liked. It certainly won’t prevent any type of diversion or misuse.”

Nevertheless, as is often the case in opioid research, sweeping conclusions were drawn from skimpy evidence. The UTMB researchers found enough “hypothetically significant clinical implications” to call for full-time monitoring of patients and their opioid use.

“These results highlight the limits in our understanding of naturalistic patterns of daily opioid use in chronic pain patients as well as support the use of MEMS for detecting potential misuse as compared to routine adherence monitoring methods. Future research directions include the need to determine how MEMS could be used to improve patient outcomes, minimize harm, and aid in clinical decision-making,” they concluded.

There is a company working on just that. Kansas-based SMRxT supplied UTMB researchers with the MEMS bottles and data used in the study. The company says its MEMS technology could be used to assign risk scores to patients – what it calls an “Absolute Adherence Score” – similar to the controversial Narxcare scores that assess a patient’s risk of opioid misuse and addiction based on their prescription drug history.   

“The SMRxT medication adherence system accurately captures data to reveal how patients take their medication. The system empowers and improves patient behavior,” the company claims in promotional material. “Once the prescription is filled, the device is ready to use. The system then translates data into actionable information for patient interventions and engagement.”

“We enjoyed working with the team at UTMB,” a spokesperson for SMRxT told PNN. “Our device is not in the development stage, and has been used by patients all over the country and many other academic research institutions.”

Research Confirms What Women Already Know About Sex Bias in Pain Care

By Crystal Lindell

There’s a new study showing that doctors take pain reported by male patients more seriously than female patients. And I have to say – why are we still doing studies on this? 

Anybody who’s been paying attention already knows this is the case. We have known it’s been true for decades. What we actually need are studies on what can be done to effectively fix this sex bias. 

For the sake of relaying this important information one more time though, let’s look at the study, which was published in the journal PNAS. The researchers did an analysis of emergency room patient data in the U.S. and Israel, which showed that there is medical bias against female patients in pain management decisions.

They analyzed more than 21,000 patient records and found that female ER patients across every age group were consistently less likely to receive pain medication compared to male patients with similar complaints. 

Depressingly, this bias persists across different ages, pain levels, and even physician gender. Which means female doctors are just as guilty as male doctors.

"This under-treatment of female patients' pain could have serious implications for women's health outcomes, potentially leading to longer recovery times, complications, or chronic pain conditions,” says Shoham Choshen-Hillel, PhD, Associate Professor at The Hebrew University of Jerusalem.

Yeah – and pardon my French here, but – no shit. Like I said, anyone who’s been paying attention has known this for a long time. Many of us have already been living with the so-called “serious implications.” 

Way back in 2014 – a full decade ago – I wrote about my experiences as a woman in pain. At the time, I wrote: 

“Being in pain every day, all day, is hard. But when you’re a woman, there’s a whole extra layer to the situation that makes everything that much harder… 

Like did that male doctor just give me Aleve for my level-10 pain because he really thinks that’s going to help? Or did he just think that, as a woman, I was probably exaggerating?”

Now that I’m 10 years older, and 10 years more experienced as a patient with chronic illness, I can answer my own question: Yes. He definitely thought I was exaggerating. 

But I’m not the only one who’s been talking about sex bias in pain care for a long time. 

The advocacy organization for women in pain, “For Grace” was founded in 2002 – more than 2 decades ago! Their mission is “to increase awareness and promote education of the gender disparity women experience in the assessment and treatment of their pain.” 

A 2001 study of gender bias in the Journal of Law, Medicine & Ethics was given the headline "The Girl Who Cried Pain: A Bias against Women in the Treatment of Pain." 

And here's another one from the last century (1996) in The Journal of the International Association for the Study of Pain titled, "Gender variations in clinical pain experience"

The fact that female pain isn’t taken as seriously as male pain is not new! 

Solutions Needed

Researchers behind the latest study do call for solutions, asking for “urgent policy interventions to address this bias and ensure equal pain treatment regardless of sex.” 

Specifically, they recommend training programs for healthcare professionals to recognize and counteract sex bias, and say pain management protocols should be revisited to ensure fair and adequate treatment for all patients.

All great ideas. But not really new ones. 

Now we need new training programs to undo the ingrained patriarchal bias among doctors. Because whatever they’ve been trying clearly isn’t working. 

Continuing to do more and more research showing that what women have been complaining about for decades is true doesn’t help anyone. We need solutions. 

This is where I’m going to get a little bit radical. Because personally, when it comes to pain treatment, I already have a very good solution: A lot more pain medication needs to be sold the same way alcohol is – over the counter. We cannot trust doctors – even female doctors – to give it to women when we need it.

This would not solve the problem of female pain being ignored, but it would at least provide some immediate relief for women, as well as others, who often have their pain ignored because of sexism, cultural bias, racism and classism. 

This is also a large part of why I believe pain control and access to pain medication is a “my body, my choice” issue. Until we have medical training that can actually undo thousands of years of sexism, we should all have the legal right to treat our own pain when doctors refuse to take it seriously.  

In the meantime, we don’t really need more studies showing that there’s a sex bias in pain treatment. They’re essentially a waste of time at this point. What we need are solutions to a problem that millions of people have been aware of for a very long time.

'Screaming Woman' May Have Died in Agony 3,000 Years Ago

By Pat Anson

The ancient Egyptians were well practiced in using natural substances as medicine. Opium was used as an analgesic and to help people sleep. Willow tree bark (later used to develop aspirin) was used as an anti-inflammatory and pain reliever. Extracts from carob trees were used as antidepressants. And they rubbed moldy bread on infected wounds centuries before penicillin was discovered.

“The range of conditions treated and the various conservative and surgical treatments used are astounding,” a German oncologist wrote after spending a year studying the history of Egyptian medicine.

But those ancient remedies failed when it came to treating a middle-aged Egyptian woman who apparently died in agony 3,000 years ago. Her mummy was discovered in 1935 and soon became known as the “Screaming Woman” because her mouth was wide open, as if locked in a permanent scream.

Only recently have researchers used CT scans and other advanced imaging techniques to “virtually dissect” her body and learn more about her life and death. Their findings were recently published in Frontiers in Medicine.

“The Screaming Woman is a true ‘time capsule’ of the way that she died and was mummified,” said lead author Sahar Saleem, MD, a professor of radiology at Kasr Al Ainy Hospital of Cairo University.

Saleem and her colleagues estimate the woman was about 48 years old at the time of her death and suffered from mild arthritis of the spine.

Her body was unwrapped and in good condition – for a mummy – laying on her back, with her legs extended and her hands folded over her groin, with no obvious sign of injury or trauma.

Unlike other mummies, the woman still had all of her internal organs, including the brain, heart, lungs and kidneys, which are normally removed during the embalming process. She was missing several teeth, which were apparently removed before her death because her mouth had time to heal.

“Teeth lost during life may have been extracted. Dentistry had originated in ancient Egypt, with Hesy Re the first recorded physician and dentist in the world,” said Saleem.

Access to a dentist and the fact that the woman was embalmed in juniper and frankincense -- costly materials that were imported -- suggest she came from a wealthy family. She was wearing two gold and silver rings when her coffin was found and had a lengthy wig made from palm fibers. 

Researchers were unable to determine a cause of death, but speculate that she died during extreme physical or emotional pain that made her scream. Rigor mortis may have quickly set in after her death, locking her facial muscles and ligaments in place.

“The mummy's screaming facial expression in this study could be read as a cadaveric spasm, implying that the woman died screaming from agony or pain,” said Saleem.

Cadaveric spasm is a rare form of muscular stiffening, typically associated with violent deaths under extreme physical conditions and intense emotion. Other academics might dispute that interpretation, because decomposition or embalming could also alter a body’s facial expression.

“The true history or circumstances of the death of the woman… are unknown; hence, the cause of her screaming facial appearance cannot be established with certainty,” researcher concluded.

Mental Health Needs of Chronic Pain Patients Often Go Untreated

By Pat Anson

People who live with chronic pain often experience anxiety and depression, but they are far less likely to have access to mental healthcare in the U.S. than those who do not have persistent pain, according to a new study.

Nearly 52 million American adults have chronic pain – about one in every five. Over 43% of them have a need for mental health treatment, compared to just 17.4% of adults who do not have chronic pain.

“People living with chronic pain may form a distinct population with special mental health care needs,” said lead author Jennifer De La Rosa, PhD, strategy director for the University of Arizona Health Sciences Comprehensive Center for Pain & Addiction. “Improving health care for people with chronic pain includes not only connecting people to care, but also addressing a disproportionate failure to achieve relief.”

De La Rosa and her colleagues reviewed findings from the 2019 National Health Interview Survey, which collected health information from a representative sample of nearly 32,000 U.S. adults. Their findings, recently published in the journal PAIN, show that just 44.4% of those with chronic pain, anxiety and depression had their mental health issues adequately treated, compared to 71.5% of those without pain.

“There are many possible reasons an individual with chronic pain might have suboptimal mental health experiences, including the accessibility of care and the feasibility of attending appointments,” De La Rosa said in a statement. “Additionally, few mental health providers are trained in chronic pain, so only a small percentage of people living with chronic pain are likely receiving mental health treatment that is designed to address their needs.”

It is not specifically addressed in the U of A study, but many patients on opioid pain medication no longer have access to benzodiazepines – a class of anti-anxiety medication that includes Xanax and Valium. Once commonly prescribed together, insurance companies and medical guidelines now strongly discourage that practice, due to fears that the two drugs raise the risk of an overdose.

In 2016, the CDC warned doctors to avoid co-prescribing opioids and benzodiazepines “whenever possible.” That same year, the FDA updated its warning labels to state that taking the drugs concurrently could result in “profound sedation, respiratory depression, coma and death.”

Even when mental health medications or therapy are offered, pain patients may be reluctant to accept them.

“Some patients may interpret mental health screening as potentially discrediting perhaps reflecting provider's doubts as to the legitimacy of self-reported pain,” the U of A researchers said. “Patients may also fear that acknowledging mental health comorbidity will reduce the likelihood of being prescribed opioids. The heightened mental health treatment stigma experienced by patients with chronic pain may lead many patients to resist the conceptualization of their chronic pain as having any emotional or mental components.”

A recent study by the same research team estimated that 12 million U.S. adults with chronic pain have  anxiety or depression so severe that it limits their ability to work, socialize and complete daily tasks. To improve patient outcomes, researchers say the routine evaluation of pain patients for anxiety and depression should become “a cornerstone of mental health policy.”

It’s All In Your Head: How Brain Circuitry Causes Placebo Effect

By Crystal Lindell

The placebo effect is very real. But how and why it happens has mostly remained a mystery. 

However, new research may shed light on what exactly is happening in our brains when just the expectation of pain relief is sufficient for people to feel better, even when the pill or treatment they’re taking has no therapeutic value.

The discovery may even lead to new treatment options. 

In studies on laboratory mice, researchers at the University of North Carolina School of Medicine discovered a pain control pathway that links the front of the brain, through the middle region of the brainstem, to the cerebellum in the back of the brain.

They then showed that certain parts of this pathway are activided in mice when they anticipate pain relief. 

“Our results do open the possibility of activating this pathway through other therapeutic means, such as drugs or neurostimulation methods to treat pain,” says lead researcher Greg Scherrer, PharmD, associate professor in the UNC Department of Cell Biology and Physiology, who conducted the study along with colleagues at Stanford, the Howard Hughes Medical Institute, and the Allen Institute for Brain Science. 

The research, recently published in the journal Nature, provides a new framework for investigating the brain pathways underlying other mind-body interactions beyond the ones involved in pain.

“We all know we need better ways to treat chronic pain, particularly treatments without harmful side effects and addictive properties,” Scherrer said. “We think our findings open the door to targeting this novel neural pain pathway to treat people in a different but potentially more effective way.”

How Scientists Studied Placebo Effect

The placebo effect is basically the brain’s way of trying to help us feel better. As such, just the expectation of pain relief is often enough to make our brains release hormones and natural chemicals that provide relief. Positive thinking and even prayer have been shown to provide similar benefits to patients, without the use of medication. 

The scientific community’s understanding of the placebo effect primarily came from human brain imaging studies, which showed increased activity in certain brain regions. However, those studies did not have enough precision to show what was actually happening in those brain regions. 

So Scherrer’s team designed a set of complex experiments to learn in more detail what was happening in the brain.

First, they created a method to generate in mice the expectation of pain relief. Then they used a series of experiments to study the anterior cingulate cortex (ACC) of their brains, which had previously been associated with the placebo effect. 

The experiments helped them see the intricate neurobiology of the placebo effect on the receptors, neurons, and synapses of the brain. When mice expected pain relief, it boosted signaling along the pain pathway.

“There is an extraordinary abundance of opioid receptors here, supporting a role in pain modulation,” Scherrer said. “When we inhibited activity in this pathway, we realized we were disrupting placebo analgesia and decreasing pain thresholds. And then, in the absence of placebo conditioning, when we activated this pathway, we caused pain relief.”

In a 2021 study, researchers had a similar breakthrough when studying the placebo effect. Researchers at Dartmouth University conducted an analysis of neuroimaging studies involving over 600 healthy people who participated in placebo studies. Their findings showed that placebo treatments reduced pain-related activity in multiple areas of the human brain.
