Fibromyalgia
unknown
The cause of fibromyalgia is unknown; however, it is believed to involve a combination of genetic and environmental factors, with each playing a substantial role.[4][5] The condition runs in families and many genes are believed to be involved.[8] Environmental factors may include psychological stress, trauma and certain infections.[4] The pain appears to result from processes in the central nervous system and the condition is referred to as a "central sensitization syndrome".[3][4] Fibromyalgia is recognized as a disorder by the US National Institutes of Health and the American College of Rheumatology.[5][9] There is no specific diagnostic test.[5] Diagnosis involves first ruling out other potential causes and verifying that a set number of symptoms are present.[4][5]
