I know what you mean. This spring when I started shooting for the fall season I felt the same pain. I tried pulling my bow back differently and it worked for a while but didn't solve the pain. I lowered the weight down to 65lbs and that helped a little. My doc gave me some anti-inflammatory meds and that took the edge off. But if it continues he wants to look into it further. I'm not sure if I want to do that. I've dealt with it for almost a
year already. I tried to lift weights with it and almost dropped the bar on my head. If you can still lift with it, I would hold off on the shoulder excersices and shooting for a couple of weeks, lowered your draw weight and try it again. Good luck.
