How is FMS diagnosed?
A. Laboratory or x-ray findings are not needed to diagnose FMS, however, often times numerous tests are conducted to rule out other conditions. According to the American College of Rheumatology the 1990 criteria requires a history of widespread pain [minimum 3 months]. The pain pattern must include both right and left sides of the body, be located above and below the waist and also include the axial skeletal region. On digital examination pain must be noted in at least 11 of 18 characteristic tender point sites.
