When my tendonitis flair up in my shoulder, I first of all cut down on my shooting and make my practice sessions exteme quality instead of quantity. I also switched to a 65% let off (I'm not sure if it will help on the wrist). I'm just wondering what is hurting it, actual strain from shooting, of shock vibrations, recoil. You may want to look into that further. I also ice, and take and ibuprofin before and after shooting.
