- Also known as fibromyalgia, this disorder chronically causes pain, stiffness, and tenderness of muscles, tendons, and joints without detectable inflammation. Fibromyalgia does not cause body damage or deformity. However, undue fatigue plagues 90% of patients with fibromyalgia. Sleep disorder is common in patients with fibromyalgia. Fibromyalgia can be associated with other rheumatic conditions. Irritable bowel syndrome can occur with fibromyalgia. There is no test for the diagnosis of fibromyalgia. Treatment is most effective when it incorporates combinations of education, stress reduction, exercise, and medication.
