Fibromyalgia does not cause body damage or deformity; however, undue fatigue plagues the large majority of patients with fibromyalgia and sleep disorders are common.
It is considered an arthritis-related condition; but,it is not a form of arthritis (a disease of the joints) since it does not cause inflammation in the joints, muscles, or other tissues or damage them.
Fibromyalgia can (like arthritis) cause significant pain and fatigue and it can similarly interfere with a person's ability to carry on daily activities.
Patients can usually dress and wash independently, but they can not cope with a job or household activities.
Patients generally score highly on measures of anxiety and depression.
