A condition found predominantly in women, fibromyalgia is defined as a chronic, diffuse, musculoskeletal pain and a sleep disorder, without evidence of arthritis or myositis. The literature initially focused on the extremities and trunk, but the head and neck are now included in the condition. Many patients presenting for treatment of masticatory muscle pain report other areas of rheumatic pain in anamnestic questionnaires, and they commonly have disturbed sleep, including bruxism. Currently, we diagnose myogenic pain as masticatory or head and neck fibromyalgia. This is often one component of generalized fibromyalgia involving the back, abdomen, or extremities. We apply the same treatment concepts to the head and neck as those advocated for fibromyalgia of the lower quadrants.
