This study found that most people with ME/CFS (76%) also experience other chronic pain conditions, such as migraines, fibromyalgia, lower back pain, and irritable bowel syndrome. These overlapping conditions were much more common in ME/CFS patients compared to healthy people (only 17% had them). When patients had multiple pain conditions alongside their ME/CFS, their overall symptoms and quality of life were significantly worse, especially for women.
Understanding how common overlapping pain conditions are in ME/CFS can help clinicians recognize and treat these comorbidities, potentially improving patient outcomes. The finding that these conditions significantly worsen symptoms suggests that targeted assessment and management of these pain conditions could meaningfully improve quality of life for ME/CFS patients. This research validates the lived experience of many patients who struggle with multiple overlapping conditions.
This study cannot establish whether these pain conditions cause ME/CFS, result from it, or share common underlying mechanisms—it only shows they frequently occur together. The cross-sectional design means we cannot determine the temporal sequence of when conditions developed. Results from specialty clinics may not reflect the broader ME/CFS population, so these prevalence rates may not apply to all patients with ME/CFS.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
