Fibromyalgia Syndrome (FMS) FMS is characterized by fatigue, sleep impairment, and widespread migrating pain. The term "FMS" means pain in the muscles, ligaments, and tendons. Because its symptoms are common with many other conditions, and laboratory tests generally appear normal, a person with FMS is often told that symptoms are "all in your head." However, medical studies have proven that FMS exists and affects approximately 3 to 6 million people in the United States. Of these, 80 to 90 percent are women.

FMS pain is more than normal muscle aches common after physical exertion. People suffering from FMS hurt all over, and frequently feel exhausted for no apparent reason. Their pain generally lingers for months and is usually followed or accompanied by stiffness. Sufferers often wake up feeling tired even though they seem to have gotten enough sleep. The condition can, at times, be severe enough to keep one from going to work, attending school, caring for the family, or maintaining close personal relationships. FMS is not a psychological condition, although it has some psychological components. As with other conditions that cause chronic pain, it's not unusual for people with FMS to develop anxiety and depression, which can aggravate their symptoms.

It may be comforting to know that FMS isn't progressive or life threatening. With appropriate treatment and self-care, symptoms can be reduced and quality of life can be improved.
