I had the same thing in my left shoulder. I went to the doctor and he gave me a prescription for 800 mgs of Ibuprrofen and tylenol with codine (I can't take Aleve). I took the medicine for a few days, but didn't get "instant" results and stopped taking it. It took about two months before I felt better. Now my right shoulder and right arm hurts. I went to the doctor again. This time I had bursitis in the shoulder and tennis elbow. It is really painful in the mornings. It has been about two months now for that and it is finally getting better on its own. I feel all of this has to do with too much quilting, but I wont quit.
