In both of my shoulders and my back, I have alot of knots in my muscles. In my left shoulder in between my neck and shoulder, one of the knots is HUGE. Recently it has been causing me alot of pain when I play pool. Sometimes even playing for a half an hour causes me enough pain that I need to stop. Has anyone else had similar problems playing pool because of knots in your neck/back muscles? I am planning on getting professional help to get rid of all of the knots in my shoulders and back. I am not sure if I should see a massage therapist, chiropractor, or is there another type of profession that specializes in removing knots? Thanks.
