Fibromyalgia (FM) is a poorly understood chronic pain condition that primarily afflicts women. Patients with fibromyalgia complain that they feel fatigued and ache all over as if they have the flu. They are generally otherwise healthy women and there seems no obvious reason for their pain. Many were very productive before they became afflicted. Symptoms can range from mild to severe but will persist for years. There is no known cause and there is no known cure.
