Myofascial Pain Syndrome
Myofascial pain syndrome refers to a disorder affecting the fascia, or connective tissue that covers a muscle or muscle group. An injured muscle may form a “trigger point,” or a taut fibrous band of collagen. A trigger point is actually a “knot” felt deep in muscle tissue, that causes pain in the muscle and in a related limb (so-called referred pain). Many times the muscle becomes spastic, and numbness in the arm or hand may occur. Myofascial pain syndrome can be mistaken for a pinched nerve, but the treatment is different.
