Fibromyalgia is a common syndrome in which a person has long-term pain that is spread throughout the body. The pain is most often linked to fatigue, sleep problems, headaches, depression, and anxiety.
People with fibromyalgia may also have tenderness in the joints, muscles, tendons, and other soft tissues.
The cause is unknown. Possible causes or triggers of fibromyalgia include:

- Abnormal pain response: Areas in the brain that control pain may react differently in people with fibromyalgia.
- Sleep disturbances.
- Infection, such as a virus, although none has been identified.
Fibromyalgia is most common among women age 20 to 50.
