Ive had bursitis in my hips and buttocks. Ive also had cortisone. But I believe bursitis is a SYMPTOM of a structural problem which then irritates the bursa sac. Unless you correct the structural problem you will have your bursitis coming back. Could be neck, upper back, shoulder. Mine was the ligaments became loose holdig my joint in place You cant see it on xrays. Stabilizing the ligaments (strengthing) them then supports the joints. Doctors treat the "SYMPTOM" of Bursitis but WHY????? did you get it in the first place you must ask yourself. You should read, Prolo your pain away. It helped me!
