On Sept 26 2011, I pulled a muscle in my shoulder blade and went all the way down my arm. It took my breathe away. I saw the Drs next day and he said pulled muscles. Gave me Inflammated drug and sent me to physical therapy. That last two weeks and follow up appointment , it was worst. Had a xray showed calium build up on top where shoulder meets the ball. He then sent me to a Specialist. The specialist then sent me for a mri. It showed mass Inflammation. He then gave me a Cortisode shot..which never helped. I am now schedule for a 1 A and a A C Joint Injection , under xray. Did anyone had that done? Also did it helped? The pain I have now is a rubbing feeling on top of shoulder blade and pain that shoots down to wrist. Any help would be appericated. By the way I got this injury from trying to open a broken door , which I didnt know was broken.
