Fibromyalgia is a chronic disorder characterized by widespread musculoskeletal pain, fatigue, and tenderness in specific areas of the body. It often coexists with symptoms such as sleep disturbances, cognitive difficulties (“fibro fog”), and mood disorders like anxiety or depression. The exact cause is unknown, but it is thought to involve abnormal pain processing in the central nervous system. Diagnosis is clinical, based on symptoms and the exclusion of other conditions. While there is no cure, treatment includes a combination of medications, physical activity, stress reduction, and cognitive behavioral therapy.
