About 2 months ago my bike slid out from under me on a hairpin turn. Wet ground, debris. Anyway my shoulder has ached badly since. Ortho Doc was going to give me a shot but sent me for an MRI and said most likely surgery was needed. Still need the MRI, first time around I was too fidgety and the nurse said I need to return with a sedative. Not looking forward to the MRI or the surgery but need to take care of this. It does start to ache when I ride for more than an hour. I also don't dare go off road. Every time I go around that corner now I take it at a crawl...I am such a baby. You may want a second opinion from another ortho doc.
