Fibromyalgia is a common neurologic health problem that causes widespread pain and tenderness (sensitivity to touch). The pain and tenderness tend to come and go, and move about the body. Most often, people with this chronic (long-term) illness are fatigued (very tired) and have sleep problems. The diagnosis can be made with a careful examination. Fibromyalgia is most common in women, though it can occur in men. It most often starts in middle adulthood, but can occur in the teen years and in old age. You are at higher risk for fibromyalgia if you have a rheumatic disease (health problem that affects the joints, muscles and bones). These include osteoarthritis, lupus, rheumatoid arthritis, or ankylosing spondylitis.
