The most notable symptoms of fibromyalgia are generalized aching or stiffness that seem to be all over the body for at least three consecutive months and tenderness upon palpation of at least 11 of 18 characteristic tender points (see diagram, below).

Other symptoms include fatigue, chronic headache, sleep disturbances, joint swelling, irritable bowel syndrome, and neurological or psychological complaints. You might also experience depression, PMS, or restless leg syndrome. Some people experience what is called Raynaud's Phenomenon/Syndrome, a condition in which your hands turn very white and cold. Yet others may experience anxiety, dry eyes or mouth, memory lapses, inability to concentrate, and arthritis.
Severity of symptoms may depend on your stress level, your activity level, and weather changes.
