Naproxen worked for me some years back. Don't know if its still available through prescription or not.I also shoot with bow quiver on and have to stay away from the faster bows (over 190)  longbow's do me in also, although I'd love to shoot one.

I got lucky that I had it. It hurt doing alot of stuff but not by shooting. I believe I got it from running equipment at work. I relaxed and when I found what hurt it I would avoid that with that arm. It took a while to over it but finally I did.

Do not rest and do not take nsaids. You need eccentric exercise. Im a big weightlifter who developed tricep tendonitis in my bow arm. I did all of the above. Finally went to a sports medicine guy and within a week of eccentric rehab, the pain went away forever. I had had it for four months
