Thanks for the reply. My insurance company has approved it so, given that the risk of making it worse is 0, I will probably go forward.
I've been through the tennis elbow thing, too. In my case, they finally did surgery and found a bone spur in an area that was continually causing tears/inflammation. No amount of rest, cortisone, etc. , etc. would ever have healed it. The good news is that after the surgery--full recovery with no pain.
Thanks again and good luck!
