This is interesting. About two months ago I got a three shot series of rooster comb injections in my right shoulder. Getting them didn't hurt at all. With the first one I could feel the bone move but it didn't hurt at all. It has given me total pain relief in my shoulder. I don't have good range of motion and I have pain in the muscles in both my upper arms which I don't understand. I got Cortisone injection in my left shoulder and it is pain free too except as I said the muscles in my arm.
I hope that helps you.
