Fibromyalgia is a condition causing widespread muscle and joint pain that affects many people worldwide. This review examines what we know about fibromyalgia's causes, how doctors diagnose it, and how it can be treated. The authors note that fibromyalgia likely results from multiple factors involving the nervous system, brain chemistry, and immune function, and that treatment typically involves antidepressants, therapy, and other approaches.
This study is relevant to ME/CFS because fibromyalgia and ME/CFS frequently overlap and are often confused clinically. Understanding fibromyalgia's proposed mechanisms—central nervous system dysfunction and immune abnormalities—may illuminate shared pathophysiology with ME/CFS. Accurate differentiation between these conditions is essential for appropriate patient management and research.
This review does not establish causation for any proposed mechanism of fibromyalgia, nor does it provide definitive diagnostic criteria or prove treatment efficacy. The paper does not present new experimental data and relies on prior literature; therefore, it cannot definitively separate fibromyalgia from chronic fatigue syndrome or establish which mechanisms are primary versus secondary. It does not demonstrate that psychotherapy is curative or that the proposed etiologies are exhaustive.
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 →
