Fibromyalgia Syndrome (FMS) is a leading cause of Social Security Disability and Long Term Disability Insurance Claims. Anyone who comes in contact with patients with FMS knows its disabling effects. However, much about the disease remains unknown. One Social Security Judge referred to it as a “pervading mystery – its cause, duration and functional limitations.” These cases can be won if the symptoms and the functional effects are made clear to the social security judge or the disability insurance company.
