It's really difficult when you're in pain to even think of something to add even more pain. Surgery is very risky alone and even more with RSD, and weighing the odds is even more difficult. Talking to your doctor is easy if he/she will listen to your concerns.

I had the surgery after I was diagnosed and it helped me. I am not recommending anything to do with surgery at all. What I am suggesting is, talk to your doctor, ask about what your options are. Maybe ask about a hand specialist, because it really sounds like a trapped nerve. But please remember I am not a health practicioner, and I only know what happened to me.

I hope I am helping.
