Hi John - I was faced with the same issue last winter, and my hip surgeon, whom I trust, diagnosed bursitis & sciatic irritation. We decided to try exercise & ice first - fortunately it works - as long as I continue daily stretching as directed. I can sleep on my left hip now - just wish my left shoulder would cooperate - 2 months of therapy & it is only marginally improved. He said if pain continued he would use cortisone. In his opinion, there is not enough evidence for PRP after healing yet. He says some of his partners do use it in the healing phase, especially if pain persists.
