The primary symptoms of fibromyalgia include widespread musculoskeletal pain, severe fatigue, and disturbed sleep. Fibromyalgia means pain in the muscles, ligaments, and tendons – the soft fibrous tissues in the body.
Most patients with fibromyalgia say that they ache all over. Their muscles may feel like they were pulled or overworked. Sometimes fibromyalgia symptoms include muscle twitches and burning sensations. More women than men are afflicted with fibromyalgia, and it shows up in people of all ages. A conservative estimate of its prevalence is 2% of the general population, but it may be as high as 3-5%.
