I guess I have hurt a shoulder again. My right one this time but it is different from when I hurt the left. The pain is an achy pain and feels below the surface except right at the end of my shoulder blade at the shoulder. there is feels like a bruise. I have some lose of strength but i cannot honestly teel if it is from it hurting when I left. Pushing movements tend to hurt (bench, military press, etc) while pulls do not. Any suggetions as to what it could be?
