Botox might help you a lot! I had it in my shoulder when it froze up. It took a month or so but it became much better. I went to a neurologist who specializes in injections of all kinds. He told me as he was doing my shoulder that he uses it all the time on people that have clenched hands.

I'd sure try it before an ablation. If you look up ablations here on this board, you'll see lots of posts about them. I don't think they have helped very many.

There are posts about botox too. You will see some of mine that I had a bad reaction to it, so they won't do it again, but it did help. Dr. said that I am one of the few people he has heard of to have a bad reaction. All that happened is that it made my pain worse for a few weeks. Then, the muscles released and it was a lot better.
