M79.70: Fibromyalgia Multiple sites

You have fibromyalgia.

Fibromyalgia is a condition that causes long-term pain. The precise cause of the condition is not known. The condition often causes pain in areas near to joints. These may be areas around the shoulder or hip, for example. Tendons are joined to bones in these areas. Muscles are attached to the bone by tendons.

The condition can cause other problems as well as pain. For example, the person may not be able to sleep properly, so suffer from fatigue. Sometimes there may also be mental issues. The hands and feet may swell up, or the skin may tingle.
