Fibromyalgia is a term referring to a pattern of generalized pain all over the body, but without any visible signs of inflammation or change. It is common and affects people of all ages, but occurs predominantly in women.
While fibromyalgia can occur by itself, it can also be associated with or overlap with several other diseases and syndromes.
An important component of fibromyalgia is that, besides pain, it affects functioning in many ways. Mood disorders (such as depression), thinking and memory impairments, sleep disturbances, chronic fatigue, headaches and high sensitivity to touch, frequent allergies, and sinusitis are some of the ways fibromyalgia seems to affect how people function.
