A common area for shoulder pain is along the inside edge of the shoulder blade (the scapula). This is often due to tight pectoral muscles over the chest at the front. When these pectoral muscles tighten, trigger points within them keep the muscles shortened and as a result pull the bones of the whole shoulder girdle forward. This then gives the appearance of ’round shouldered’ and flat chested.
A deep tissue massage will soon lengthen these pectoral muscles again and the shoulder pain should cease. These muscles often shorten from the posture of habitually leaning forward such as driving or to use a computer, or heavy carrying on a regular basis – often parents having to carry small children.
