Chronic Pain Insights and Trends

• In 2025, the total number of diagnosed prevalent cases of chronic pain in the 7MM was around 115 million. Among the 7MM countries, the US accounted for the highest number of diagnosed prevalent cases, contributing approximately 45 million cases.
• Among EU4 and the UK, Germany accounted for the highest diagnosed prevalence of chronic pain, with ~15 million of the total cases. In contrast, with only approximately 10 million cases, Spain reported the lowest diagnosed prevalence of chronic pain in 2025.
• The persistent predominance of females suggests a greater chronic pain burden among women in 7MM, potentially reflecting differences in the prevalence of pain-associated musculoskeletal conditions, aging patterns, and healthcare-seeking behavior.
• Chronic low back pain and osteoarthritis remain major contributors to the chronic pain burden across the 7MM, while migraine, neuropathic pain, fibromyalgia, and rheumatoid arthritis-associated pain represent additional important underlying conditions contributing to the overall patient population.
• The treated population is expanding in parallel with the diagnosed population, demonstrating that the growing epidemiological burden is translating into an increasingly large actively managed patient pool. This is important from a market perspective because it indicates that future growth is not dependent solely on new diagnosis; existing diagnosed patients are also contributing to sustained treatment demand.
• The severity profile shows a substantial concentration of patients with moderate and severe chronic pain, with both segments projected to expand over the forecast period. This indicates that growth is not limited to lower-intensity symptoms and highlights a clinically relevant opportunity for stronger, sustained, or multimodal pain-control therapies for patients with greater disease burden.

Chronic Pain Understanding

Chronic Pain Overview and Diagnosis

Chronic pain is a complex and persistent condition defined as pain lasting beyond the normal healing period, typically for more than 3–6 months. It affects a substantial proportion of the adult population and is associated with significant physical, psychological, and socioeconomic burden. Chronic pain may arise from tissue injury, disease, nerve damage, or altered pain processing, and is frequently accompanied by comorbid conditions such as depression and anxiety, which further impair quality of life and functional capacity. The condition is also associated with increased healthcare utilization, reduced productivity, opioid misuse, and elevated mortality risk.

The diagnosis of chronic pain requires a comprehensive and multidisciplinary evaluation aimed at identifying the underlying cause, determining the predominant pain mechanism, and assessing the impact of pain on physical, psychological, and social functioning. Because chronic pain may arise from musculoskeletal, neuropathic, inflammatory, visceral, or nociplastic mechanisms, diagnosis is based on a combination of clinical assessment and targeted diagnostic investigations. A thorough physical examination helps identify structural, neurological, or inflammatory abnormalities that may contribute to chronic pain. Examination typically includes assessment of posture, gait, joint range of motion, muscle strength, tenderness, swelling, sensory changes, reflexes, and signs of nerve compression or musculoskeletal dysfunction.

Chronic Pain Epidemiology

Key Findings from Chronic Pain Epidemiological Analysis and Forecast

• According to DelveInsight’s analysis, more than 20 million males and 25 million females were affected with chronic pain in the US in 2025. The continued increase across both genders by 2036 indicates an expanding chronic pain patient pool in the US, with the higher burden among females potentially reflecting differences in the prevalence of pain-associated conditions and healthcare utilization.
• Across EU4 and the UK, approximately 50 million diagnosed prevalent cases were reported in 2025. Germany accounted for the largest share, contributing around 10 million diagnosed prevalent cases, followed by the France.
• According to DelveInsight’s estimates, Moderate chronic pain accounted for the highest number of diagnosed prevalent cases across EU4 and the UK in 2025, with approximately 25 million cases, followed by Mild (10 million cases) and Severe (15 million cases).
• Japan accounted for nearly 20 million diagnosed prevalent cases of chronic pain in 2025, representing only a small proportion of the total prevalent patient population.
