Fibromyalgia is a condition that produces chronic pain of the soft tissues that may include the muscles, ligaments and tendons. Most patients with FMS say that they ache all over. Their muscles may feel like they have been pulled or overworked. Sometimes the muscles twitch and at other times they burn. These problems can be severe enough to disrupt a person's work and daily activities.
It also may produce a number of other symptoms including temperature sensitivities; numbness and tingling that may travel throughout the body, fatigue, insomnia, concentration problems, gastric upset, headaches, joint discomfort and depression.
Fibromyalgia is a syndrome of chronic pain , not a disease or a psychological disorder. More women than men are afflicted with FMS, and it shows up in people of all ages. Fortunately, the condition does not permanently damage the muscles, joints, or internal organs.
