What is fibromyalgia?

Fibromyalgia is a chronic condition that causes pain, stiffness, and tenderness of the muscles, tendons, and joints. Fibromyalgia is also characterized by restless sleep, awakening feeling tired, chronic fatigue, anxiety, depression, and disturbances in bowel function. Fibromyalgia is sometimes referred to as fibromyalgia syndrome and abbreviated FMS. Fibromyalgia was formerly known as fibrositis.

While fibromyalgia is one of the most common diseases affecting the muscles leading to chronic pain and disability, its cause is currently unknown. The painful tissues involved are not accompanied by tissue inflammation. Therefore, despite potentially disabling body pain, people with fibromyalgia do not suffer from body damage or deformity. Fibromyalgia also does not cause damage to internal body organs. In this sense, fibromyalgia is different from many other rheumatic conditions (such as rheumatoid arthritis, systemic lupus, and polymyositis). In those diseases, tissue inflammation is the major cause of pain, stiffness, and tenderness of the joints, tendons, and muscles, and it can lead to joint deformity and damage to the internal organs or muscles.
