Nociceptive aspects of fibromyalgia.
Although characterized by a variety of symptoms, chronic widespread pain is the primary complaint bringing most patients with fibromyalgia syndrome (FMS) into the clinic. The etiology of this painful condition is unknown, and any possible relationship between pain and the many other symptoms of FMS is unclear. This article focuses on the unique characteristics of nociception in patients with FMS. The intent is to present criteria that should be considered in the search for biological events that contribute to FMS pain. Based on this approach, examples are proposed of factors that fulfill some criteria and may, therefore, deserve further study for their possible role in pain associated with FMS.
