Myofascial is derived from the words “myo” which means muscle, and “fascia” which is the connective tissue that covers and intertwines with muscle. Myofascial pain is generated by hyperactive small areas of irritability in muscle or its associated fascia that are called myofascial trigger points. A trained examiner can usually feel these trigger points. The diagnosis is determined by physical examination, and not by medical tests such as X-ray, CT and MRI scans.
Myofascial Pain Syndrome is generated by myofascial trigger points in muscle tissue. Trigger points can be felt as nodules or knots of tightness within a muscle. Trigger points form in muscle tissue as a response to injury. They generate pain patterns that are felt as aching, numbness, tingling, and cramping. This pain pattern may be felt in a muscle or a nearby joint. The trigger point will also restrict motion, cause weakness and cause tightness in the soft tissue.
