Okay, after my compound lifts today I was going to do some isolation work.
I did my first set of 25 pull-ups, and then I went to do my next set of 20. I was doing where I would pull up then at the top of the bar slide all the way to the right, then to the left. But on rep 7 I felt an immediate sharp burning type of pain in my upper right shoulder. I dropped instantly, and a few minutes after it happened I couldn't turn my head to the left or I would feel the pain. And I also couldn't move my arm to the left. Now about 20 minutes after it has happened, I can feel soreness in my shoulder, but I can now turn my head left, but not all the way..
Did I pinch something? Or.. I'm trying to avoid the doctor here..
