Fibromyalgia is the second most common rheumatic disorder behind osteoarthritis and, though still widely misunderstood, is now considered to be a lifelong central nervous system disorder, which is responsible for amplified pain that shoots through the body in those who suffer from it.
Daniel Clauw, M.D., professor of anesthesiology, University of Michigan, analyzed the neurological basis for fibromyalgia in a plenary session address today at the American Pain Society Annual Scientific Meeting.
"Fibromyalgia can be thought of both as a discreet disease and also as a final common pathway of pain centralization and chronification. Most people with this condition have lifelong histories of chronic pain throughout their bodies," said Clauw. "The condition can be hard to diagnose if one isn't familiar with classic symptoms because there isn't a single cause and no outward signs."
Clauw explained that fibromyalgia pain comes more from the brain and spinal cord than from areas of the body in which someone may experience peripheral pain. The condition is believed to be associated with disturbances in how the brain processes pain and other sensory information. He said physicians should suspect fibromyalgia in patients with multifocal (mostly musculoskeletal) pain that is not fully explained by injury or inflammation.
"Because pain pathways throughout the body are amplified in fibromyalgia patients, pain can occur anywhere, so chronic headaches, visceral pain and sensory hyper-responsiveness are common in people with this painful condition," said Clauw.
