This review found that pain in ME/CFS is not caused by damaged muscles or joints, but rather comes from how the nervous system processes pain signals—a condition called central sensitization. The study suggests that education about how pain works in ME/CFS, along with cognitive behavioral therapy focused on fatigue, may help patients manage their pain better.
This study challenges the misconception that ME/CFS pain is purely musculoskeletal and validates patient experiences by identifying specific neurobiological mechanisms. By proposing targeted treatments (education and cognitive behavioral therapy) with demonstrated short-term benefits, it provides evidence-based guidance for clinicians developing individualized pain management strategies in ME/CFS.
As a narrative review rather than a primary research study, this work synthesizes existing literature and does not generate new empirical data or definitive causal proof. The short-term efficacy noted for certain treatments does not establish long-term effectiveness or whether these approaches work equally well across all ME/CFS patient subgroups. The review also cannot prove that central sensitization is the sole mechanism underlying pain in ME/CFS, as other unexplored biological pathways may contribute.
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 →
