A previous question asked for the causes of fibromyalgia. So I thought it would be helpful to quote from Daniel Clauw, MD's article in The Journal of Musculoskeletal Medicine, October 2003. His article and "it appears that a variety of stressors... infections, physical trauma, immune stimulation, and emotional distress" can cause FMS. Exposure to stressors in a series or to numerous stressors concurrently may increase the likelihood of FMS occurring." In his lectures he says that genetics play a role as well as his article stating that there is strong familial predisposition.

Fibromyalgia syndrome (FMS) is a term "used to describe a muscoloskeletal condition characterized by chronic widespread pain... " In this article, Dr. Clauw references many conditions that are far more frequent in people with FMS such as chronic fatigue syndrome, multiple chemical sensitivities, irritable bowel syndrome, tension and migraine headaches, noncardiac chest pain, heartburn, palpitations, sore throats, abdominal pain, pelvic pain, syncope and hypotension, dysmenorrhea, interstitial cystitis, endometriosis and sensitivity disorders such as vulvar vestibulitis and vulvodnia. Evidence of some of these illnesses are through echocardiographic results of mitral valve prolapse and esophageal dysmotility. The results of pulmonary function tests in patients with FMS have revealed reduced static inspiratory and expiratory pressure, probably because of pain in respiratory muscles. Also "persons with FMS also frequently display hypersensitivity to heat, noise, odors, and bright lights... " Associated symptoms are "fatigue, sleep difficulties, weakness, attention or memory lapses, unexplainable weight fluctuations... " He says that also common in patients with FMS, are "a high degree of adverse reactions to drugs, chemicals, and other environmental stimuli". Does any of this explain some of your other problems or characteristics?
