The characteristic symptoms of fibromyalgia are chronic widespread musculoskeletal pain in various parts of the body and abnormal tenderness at 18 specified tender points. Associated symptoms often reported include stiffness, sleep disorders, fatigue, and problems with concentration. The prevalence is about 3.5% for women and 0.5% for men. The impact of the disease is considerable both for those directly affected (restriction in activities of daily living and in ability to take part in family, professional, and social life) and for society as a whole (direct and indirect costs). The disease usually has a chronic course. An abnormality of the central pain-processing mechanisms is highly relevant for the pathogenesis. In addition to early diagnosis and intensive patient education, pharmacotherapy, exercise therapy, behavior therapy, and multidisciplinary treatment are particularly important for the management of fibromyalgia.
