30 Chronic Primary Pain Statistics That Reveal the Scope, Cost, and Treatment Gap

Current data on prevalence, economic burden, demographic disparities, and the growing evidence for behavioral and brain-based treatments

Chronic primary pain, where pain persists for months or years without a clear structural cause, now affects nearly 1 in 4 US adults. The condition costs the US economy over $635 billion annually, yet fewer than 12% of patients with chronic low back pain receive the behavioral and psychological treatments that clinical guidelines recommend. These 30 statistics document the full scope of chronic primary pain: who it affects, what it costs, where treatment falls short, and what the evidence shows about brain-based approaches.

Key Takeaways

• One in 4 US adults has chronic pain - 24.3% of Americans report chronic pain, with prevalence rising 18% from prepandemic levels
• Annual costs surpass major diseases combined - chronic pain costs the US $560-635 billion per year, more than heart disease, cancer, and diabetes
• Most back and neck pain may be primary, not structural - 88.3% of patients in one clinical evaluation met criteria for brain-based rather than structural pain
• Behavioral treatments are drastically underused - only 12% of patients with chronic low back pain have received psychological support despite guideline recommendations
• Brain-based therapies show lasting results - 55% of PRT participants with chronic back pain remained pain-free or nearly pain-free at 5 years

Prevalence and Scope of Chronic Primary Pain

1. 24.3% of US adults report chronic pain, affecting approximately 60 million people

In 2023, 24.3% of US adults reported chronic pain, affecting approximately 60 million people. Chronic pain is now more prevalent than diabetes, depression, and coronary heart disease individually. Pain is classified as chronic when it persists on most days or every day for 3 months or more.

2. 8.5% of US adults experience high-impact chronic pain that limits daily life

Among adults with chronic pain, 8.5%, roughly 22 million, report high-impact chronic pain that frequently limits work, social, or self-care activities. High-impact chronic pain is associated with greater healthcare utilization, higher disability rates, and more severe mental health comorbidity. This subgroup accounts for a disproportionate share of chronic pain's total burden on the healthcare system.

3. Chronic pain prevalence rose 18% from prepandemic levels between 2019 and 2023

Between 2019 and 2023, chronic pain prevalence rose 18% from prepandemic levels of 20.5% to 24.3%. The rise was consistent across age, sex, and racial and ethnic groups, suggesting systemic rather than subgroup-specific drivers. Contributing factors may include pandemic-related disruptions in care access, increased sedentary behavior, and heightened psychosocial stress.

4. Musculoskeletal conditions affect 1.71 billion people worldwide, driving the global chronic pain burden

Musculoskeletal conditions, the primary source of chronic pain globally, affect 1.71 billion people worldwide according to the WHO. Low back pain, neck pain, and osteoarthritis account for the largest share of the global chronic pain burden. As populations age and sedentary lifestyles become more common, global chronic pain prevalence is projected to continue rising.

5. 88.3% of back and neck pain patients in one clinical evaluation met criteria for primary pain

In a community physiatry clinic evaluation, 88.3% of patients evaluated for back and neck pain met criteria for primary (nociplastic) pain rather than pain driven by structural damage. This finding challenges the assumption that chronic back pain requires a structural explanation like disc degeneration or nerve compression. It supports the growing consensus that changes in how the brain processes pain signals maintain pain in the majority of chronic musculoskeletal cases.

6. Low back pain has been the leading cause of disability worldwide since 1990

Low back pain has ranked as the leading cause of disability worldwide since 1990, affecting an estimated 619 million people and causing 69 million years lived with disability in 2020. No other health condition, including depression, diabetes, or COPD, has surpassed it in this metric across three decades of Global Burden of Disease tracking. Projections estimate the number of affected people will reach 843 million by 2050.

Demographic Disparities in Chronic Pain

7. Women experience chronic pain at higher rates than men across all severity levels

Women report chronic pain at 25.4% versus 23.2% for men, with the disparity widening for high-impact chronic pain at 9.6% versus 7.3%. This 31% higher rate of high-impact pain among women persists after adjusting for age. Conditions that disproportionately affect women, including fibromyalgia, chronic migraine, and chronic pelvic pain, contribute to the gap.

8. Chronic pain prevalence triples between young adulthood and age 65+

Chronic pain prevalence triples with age, from 12.3% among adults aged 18-29 to 36.0% among adults 65 and older. High-impact chronic pain follows a similar trajectory, climbing from 3.0% to 13.5% across the same age range. As the US population continues to age, these figures carry significant implications for healthcare workforce planning and treatment capacity.

9. American Indian and Alaska Native adults face the highest chronic pain rates of any racial or ethnic group

Chronic pain rates reach 30.7% among American Indian and Alaska Native non-Hispanic adults, followed by White non-Hispanic adults at 28.0%, with Asian non-Hispanic adults reporting the lowest rates at 11.8%. These disparities reflect intersecting socioeconomic factors, historical healthcare inequities, and differences in environmental and occupational exposure. Addressing these gaps requires both broader access to effective treatments and culturally responsive care models.

10. Rural adults experience chronic pain at 29% compared to 21% in urban areas

Adults living in rural areas experience chronic pain at 29%, compared to 21% in urban areas, with the gap more pronounced among women (31.7% rural vs. 22.2% in large metropolitan areas). Rural populations face compounding barriers including fewer pain specialists, longer travel distances for care, and higher rates of physically demanding occupations. Virtual and digital pain care models may help bridge this geographic access gap.

Economic and Healthcare Cost Burden

11. Chronic pain costs the US $560-635 billion annually, exceeding heart disease, cancer, and diabetes combined

Chronic pain costs the US economy $560-635 billion annually in direct medical expenses and lost productivity. That figure surpasses the combined annual costs of heart disease ($309 billion), cancer ($243 billion), and diabetes ($188 billion), making chronic pain the most expensive health condition in the country. Adjusted for inflation and the 18% prevalence increase since 2019, current costs likely exceed this estimate substantially.

12. Updated 2022 analysis places the total annual burden at $725 billion

A 2022 claims analysis places the burden at $725 billion, or $447 billion excluding direct surgical costs. The gap between this figure and earlier estimates reflects both inflation and increased prevalence over the past decade. As chronic pain rates continue to rise, the economic case for effective, scalable treatments grows stronger.

13. Lost productivity accounts for $299-335 billion per year, driven by presenteeism

Chronic pain costs the US workforce $299-335 billion annually in lost productivity, with 77% of that loss attributable to presenteeism rather than absenteeism. Workers with pain show up but perform at reduced capacity, producing output losses often invisible to employers. This hidden cost makes chronic pain a significant workforce issue beyond its direct medical spending.

14. Average annual healthcare spending per chronic pain patient reaches $23,705

Per-patient healthcare costs for adults with chronic pain average $23,705 per year, encompassing medication, procedures, emergency visits, and specialist care. This figure is roughly 2-3 times the average spending for adults without chronic pain. For the estimated 60 million affected Americans, even modest per-patient cost reductions through effective treatment would translate to billions in savings.

Mental Health and Quality of Life Impact

15. Approximately 40% of adults with chronic pain have clinically significant depression or anxiety

Across 376 studies and 50 countries, approximately 40% of chronic pain patients have clinically significant depression or anxiety, with rates of 39% for depressive symptoms and 40% for anxiety. Among adults with fibromyalgia specifically, these rates climb to 54% for depression and 55.5% for anxiety. The bidirectional relationship between pain and mental health means untreated mood symptoms can sustain and amplify the pain experience.

16. 12 million US adults live with co-occurring chronic pain and anxiety or depression

An estimated 12 million US adults (4.9% of the adult population) experience co-occurring chronic pain and anxiety or depression symptoms. This overlap is not coincidental: chronic pain and mood disorders share neural pathways, and each condition lowers the threshold for the other. Integrated treatment addressing both pain and mental health simultaneously tends to produce better outcomes than treating either condition alone.

17. Up to 75% of chronic pain patients experience clinically significant sleep disruption

Among adults with chronic pain, up to 75% experience sleep disruption, measured using validated sleep quality instruments across multiple studies. Poor sleep amplifies pain sensitivity through central sensitization, creating a cycle where pain disrupts sleep and sleep loss intensifies pain. Addressing sleep as part of chronic pain treatment can improve outcomes in both domains.

18. Suicidal ideation affects 28.9% of chronic pain populations, far exceeding general-population rates

Among chronic pain populations, the pooled lifetime prevalence of suicidal ideation reaches 28.9%, with 10.8% reporting a lifetime suicide attempt. These rates far exceed general-population baselines, reflecting a substantially elevated risk of suicidal behavior. These figures underscore the urgency of comprehensive pain care that includes routine mental health screening and support.

Treatment Gaps and Access to Care

19. Only 12% of chronic low back pain patients have received psychological treatment

Despite clinical guidelines recommending behavioral approaches, only 12% received psychological support among adults with chronic low back pain, with just 8.4% receiving CBT specifically. This gap persists despite recommendations from the ACP, CDC, and IASP supporting psychological and behavioral interventions as first-line or adjunctive treatments. The disconnect between guidelines and clinical practice represents one of the most significant treatment gaps in pain medicine.

20. 75 clinical trials confirm psychological therapies reduce pain, disability, and mood symptoms in chronic pain

A Cochrane review of 75 randomized trials with 9,401 participants found that psychological therapies produce consistent improvements in pain, disability, and mood for adults with chronic pain. Effects persisted at follow-up, making this one of the most replicated findings in pain medicine. The gap between this evidence and the 12% access rate for psychological treatment represents one of the most significant disconnects in chronic pain care.

21. 40-80% of chronic pain patients may be receiving incorrect diagnoses

Estimates suggest that 40-80% may be misdiagnosed among chronic pain patients, particularly when pain persists without clear structural findings on imaging. The diagnostic challenge is well-documented in fibromyalgia, where patients wait 2.3 years on average and see 3.7 physicians before receiving a correct diagnosis. Misdiagnosis directs patients toward treatments targeting structural causes when the actual pain mechanism may be neuroplastic.

22. Pain medicine fellowship applications declined 45% between 2019 and 2023

Pain medicine fellowship applications fell 45% between 2019 and 2023, signaling a growing shortage of pain specialists in the US. This decline comes as chronic pain prevalence rises, widening the gap between patient need and available expertise. The shortage is particularly acute in rural areas, where patients already face barriers including longer travel distances and fewer specialized treatment options.

The Opioid Crisis and Chronic Pain

23. Over 1 in 5 chronic pain patients used a prescription opioid in the prior 3 months

Among US adults with chronic pain, 22.1% used prescription opioids in the prior 3 months as of 2019. While prescribing rates have declined from their peak, chronic pain remains the primary reason for long-term opioid therapy in the US. The CDC's 2022 clinical practice guideline emphasizes that non-opioid and non-pharmacological treatments should be maximized before considering opioids for chronic pain.

24. 75% of people who began misusing opioids in the 2000s started with a prescription

Among people who began misusing opioids in the 2000s, 75% started with prescriptions, a reversal from the 1960s when 80% of opioid misuse began with heroin. This shift highlights the role chronic pain prescribing has played in driving opioid use disorder. Effective non-opioid approaches to chronic pain management may help reduce this pathway to substance misuse.

25. Opioid-involved overdose deaths reached 79,358 in 2023

Opioid-involved overdose deaths reached 79,358 in 2023, though preliminary 2024 data suggests approximately a 33% decline. While illicitly manufactured fentanyl drives the majority of current deaths, the epidemic's origins trace to the overprescribing of opioids for chronic pain. Expanding access to evidence-based non-opioid treatments remains central to long-term overdose prevention.

Behavioral and Brain-Based Treatment Outcomes

26. 66% of chronic back pain patients were pain-free or nearly pain-free after Pain Reprocessing Therapy

In a randomized controlled trial of 151 adults with chronic back pain, 66% were pain-free or nearly pain-free after 4 weeks of Pain Reprocessing Therapy, compared to 20% with placebo and 10% with usual care. Effect sizes were among the strongest reported for any behavioral chronic back pain intervention. Lin Health's approach draws on findings from this and related research on brain-based pain treatment.

27. 55% of PRT participants maintained pain relief at 5-year follow-up

A follow-up of the same trial found that 55% remained pain-free or nearly pain-free at 5 years, compared to 26% with placebo and 36% with usual care. These results suggest brain-based approaches to chronic back pain can produce durable changes rather than short-term relief. The sustained benefit aligns with the theory that PRT helps the brain reclassify pain signals as non-dangerous.

28. 63% of older veterans achieved clinically significant pain reduction with Emotional Awareness and Expression Therapy

In a trial of 126 older veterans with chronic musculoskeletal pain, 63% achieved significant reduction in pain with Emotional Awareness and Expression Therapy, compared to 17% receiving CBT. At 6-month follow-up, 41% of EAET participants maintained clinically significant improvement versus 14% of CBT participants. EAET works by helping patients identify and process the emotional factors in pain.

29. The IASP now classifies nociplastic pain as a third mechanism alongside nociceptive and neuropathic pain

The International Association for the Study of Pain classifies nociplastic pain as a third pain mechanism alongside nociceptive (tissue-based) and neuropathic (nerve-based) pain. This classification recognizes that the nervous system can generate and amplify pain without ongoing tissue damage or nerve injury, validating brain-based treatment approaches. Conditions including fibromyalgia, non-specific low back pain, and chronic widespread pain fall under this central sensitization framework.

30. The CDC's 2022 guideline recommends non-opioid and non-pharmacological therapies as preferred for chronic pain

The CDC's 2022 clinical practice guideline recommends non-opioid therapies, including behavioral and psychological approaches, as preferred for subacute and chronic pain management. The guideline specifically highlights cognitive behavioral therapy, exercise therapy, and multidisciplinary rehabilitation as evidence-based options. This formal recommendation supports broader insurance coverage and clinical adoption of the behavioral and brain-based treatments reflected in the research above.

How Lin Health Helps With Chronic Primary Pain

The statistics above map a clear pattern: chronic primary pain is widespread, costly, and frequently treated with approaches that do not match the underlying mechanism. For the majority of chronic pain cases where the brain and nervous system drive the pain signal rather than ongoing tissue damage, treatments targeting those neural pathways offer a different path forward.

Lin Health's program is based on principles from Pain Reprocessing Therapy, CBT, ACT, and Emotional Awareness and Expression Therapy, the behavioral and brain-based approaches reflected in the research above. The program pairs each participant with a trained recovery coach for weekly sessions, supplemented by an app with structured learning and practice materials. Treatment addresses fear-avoidance patterns, emotional responses, and learned neural pathways that maintain chronic primary pain across multiple conditions.

Lin Health is covered by most major insurance plans in Colorado, Texas, Florida, California, and New York, with coverage expanding to additional states. Wait times are short, with many patients receiving a same-day callback after signing up. For more on the research behind the approach, explore the clinical research library, or read patient recovery stories.

If you have been living with chronic pain and have not found lasting relief through medication, injections, or surgery, behavioral and brain-based approaches may be worth exploring. Lin Health is covered by most major insurance plans, and most patients pay nothing out of pocket. See if Lin Health may help with your chronic pain.

Frequently Asked Questions

What is chronic primary pain?

Chronic primary pain is pain lasting 3 or more months that is not better explained by an underlying injury, inflammation, or structural damage. Recognized as a distinct diagnosis in the ICD-11 classification system, it includes conditions like non-specific low back pain, fibromyalgia, and chronic widespread pain. Research suggests it arises from changes in how the brain and nervous system process pain signals rather than from ongoing tissue damage.

How common is chronic pain in the United States?

Approximately 24.3% of US adults, or 60 million people, reported chronic pain in 2023. Of those, 8.5% (about 22 million) had high-impact chronic pain that frequently limited work or daily activities. Prevalence has risen 18% since 2019, with higher rates among women, older adults, rural populations, and American Indian/Alaska Native communities.

What is the difference between chronic primary and secondary pain?

Chronic primary pain persists without a clear structural or disease-related cause, while chronic secondary pain results from an identifiable underlying condition such as rheumatoid arthritis, cancer, or nerve damage. In primary pain, the nervous system itself maintains the pain signal even after any original injury has healed. Many common chronic pain presentations, including non-specific low back pain and fibromyalgia, fall into the primary category.

Can chronic primary pain be treated without medication?

Clinical guidelines, including the CDC's 2022 prescribing guideline, recommend non-pharmacological approaches as preferred first-line treatments for chronic pain. Behavioral therapies, including CBT and ACT for chronic pain broadly and Pain Reprocessing Therapy for chronic back pain, have demonstrated meaningful pain reduction in clinical trials. These approaches address the brain and nervous system mechanisms that maintain chronic primary pain rather than masking symptoms with medication.

How does chronic pain affect mental health?

Chronic pain and mental health conditions frequently co-occur. Approximately 40% of adults with chronic pain have clinically significant depression or anxiety, and 12 million US adults experience both conditions simultaneously. Chronic pain is also associated with substantially elevated rates of suicidal ideation and affects sleep quality in up to 75% of patients.

What is Pain Reprocessing Therapy?

Pain Reprocessing Therapy (PRT) is a brain-based treatment that helps patients reinterpret chronic pain signals as non-dangerous. In a randomized trial of adults with chronic back pain, 66% were pain-free or nearly pain-free after treatment, and 55% maintained those results at 5 years. PRT uses techniques including somatic tracking and corrective experiences to change how the brain processes pain.
