Just wondering if any of you have experienced a shoulder injury like this. It actually seems to hurt the most at the insertion point of the deltoid and my upper arm. Many/Most movements are painful including taking off my shirt. I play rugby and its normally when I'm pushing with that shoulder that I'll hear a "rip" sound and the pain comes. Then next day I won't be able to move it, and it pops and grinds alot....it probably doesn't help that I still continue to play rugby and lift heavy w/ it, but I'm very worried about taking steps backward in the muscle department. Anyone had similar problems?
