Fiber Cut - be very, very, very, very, very careful with cortisone shots to the tendons.
I had thought that was my answer, but the second doc I went to said NO - that the steroids can make the tendons BRITTLE and that they can then snap. He said that the risk of that happening was far too great to try it.
I'm still in PT - now to strengthen the wrist, elbow and shoulder. The pain is with me all the time - sometimes better, sometimes worse.
Good luck.
