Social influences on the concept of fibromyalgia

Despite relevant evidence of physical illness promoting fibromyalgia syndrome (FMS), some authors claim that it is a psychological illness, or due to "psychological amplification." Good evidence for such views is lacking. Selection processes lead to increased rates of psychological illness in general practice and in specialist practice. The physical distress of FMS can increase both anxiety and depression. Questionable research supported by the insurance industry has tended to provide negative and disparaging views of pain. Current imaging studies support the view that central effects connected with FMS relate to the processing of noxious stimulation more than affective disorder.
