myofascial means muscle tissue (myo) and the connective tissue in and around it (fascia). Myofascial pain often results from muscle injury or repetitive strain. When stressed or injured, muscles often form trigger points, like contracted knots, that cause pain and tightness.

Myofascial trigger points are an extremely common cause of pain. Trigger points are painful when pressed on, cause a shortening of the muscle fibers, and have a special property called referred pain. Referred pain means that a trigger point in one muscle can create pain in another area.
For instance, when the muscle at the top of your shoulder (trapezius) has a trigger point it will refer pain up the side of your neck and head causing a headache. Active myofascial trigger points in the muscles of the shoulder neck and face are a common source of headaches. In many instances the headache has the features of so-called tension headache, but there is increasing acceptance that myofascial trigger points may initiate classical migraine headaches or be part of a mixed tension/migraine headache complex.
Myofascial release is a type of physical therapy often used to treat myofascial pain syndrome. Myofascial pain syndrome is a chronic muscular pain disorder which effects any skeletal muscle in the body this pain disorder is caused by sensitivity and tightness in the myofascial tissues
