Fibrositis

Pain and stiffness in the muscles. Because investigation usually fails to reveal any underlying cause, some doctors do not recognize fibrositis as a medical condition. However, tension and bad posture may contribute. Sometimes, an attack occurs after an infection or a new exercise. Muscles most commonly affected are those in the neck, shoulders, chest, back, buttocks, and knees. There is usually no restriction of movement. Sometimes, attacks (which are generally worse in cold, damp weather) are accompanied by exhaustion and disturbed sleep. Analgesic drugs, hot baths, and massage usually relieve pain and stiffness. Exercises to improve posture may help to prevent attacks. (See also back pain.)
