Myofascial pain syndrome

Myofascial pain syndrome is caused by a stimulus, such as muscle tightness, that sets off trigger points in your muscles. Factors that may increase your risk of muscle

trigger points include:

  • Muscle injury. An acute muscle injury or continual muscle stress may lead to the development of trigger points. For example, a spot within or near a strained muscle may become a trigger point. Repetitive motions and poor posture also may increase your risk.
  • Stress and anxiety. People who frequently experience stress and anxiety may be more likely to develop trigger points in their muscles. One theory holds that these people may be more likely to clench their muscles, a form of repeated strain that leaves muscles susceptible to trigger point

the serratus anterior muscle is located on the side of the trunk. It attaches onto the ribs and the scapulae. This muscle assists in scapular motion and stability as well as assisting the movement of the ribs. Trigger points can form in this muscle due to poor shoulder posture. Once formed, these points will cause pain to be felt in the side, under the armpit, and down the inside of the arm. Once formed trigger points will not release on their own, they require a manual technique such as trigger point massage.
