I heard some things pop when I was doing pull-ups of all things.... And after the session I could not raise my arm above my head. It's been almost a week and there is bruising. I have full range of motion back but do not dare try to pull down with it. Pushing is fine. Here's a pic. Any thoughts? Not going to the doc unless it gets a lot worse. No dents or deformities and they will not do an Mri unless you are close to death or can't use the fucking thing at all.
