Fibromyalgia is a chronic condition characterized by widespread pain throughout the body, often accompanied by fatigue, sleep disturbances, and cognitive difficulties. It affects how the brain processes pain signals, leading to heightened sensitivity. The exact cause is unknown, but it may involve genetic, environmental, and psychological factors. Diagnosis of fibromyalgia typically involves ruling out other conditions, as there are no specific tests for it. Treatment often includes a combination of medications, physical therapy, and lifestyle changes to help manage symptoms and improve quality of life.
