MYOFASCIAL PAIN SYNDROMES

Fibrositis (fibromyalgia syndromes, myofascial pain syndromes) are a group of disorders characterized by chronic widespread aches and pains in the muscles, muscle sheath and connective tissues of tendons, muscles, bones and joints, with associated tenderness.
The pain and stiffness (fibromyalgia) may affect the whole body or may be restricted to certain parts of the body, as in myofascial pain syndromes. Fibromyalgia throughout the body is more common in women than in men. Men are more likely to develop myofascial pain or fibromyalgia in a particular area e.g. a shoulder ,from a work related or sports  muscle strain injury.
It is a common condition seen in 4 to 11% of the population and is  more prevalent in women. It can  affect any age group. It is not serious or life-threatening, but persistent symptoms can be very disruptive.
