Left shoulder back blade pain and top of shoulder going up left side of neck . Left arm from elbow up sore and also cant lift my arm more than straight out . I can use my right arm to lift up my arm higher . Very weak when trying to use it to carry something . Hade a massage today hoping to release the pain thinking it might be knotted up and pressing on a nerve . Still can’t lift arm up ant further sore from massage hoping it will b better in a few days . Thought this was advice not something I hade to pay for , forget it !
