I would not do this. I have heard by doctors that when you have a surgical procedure with the nerves it could damage other nerves. I also feel with any procedure there is a risk of rsd spread.
I am sorry you are in such a bad place pain wise. Are there other procedures that are more common and safe that you have no tried?

I had TWO sympathectomys ..23 years ago due to TOS.. along with both of my first ribs removed, each side... it was the result of an auto accident I was in.. I was rear ended... Very long, painful recover..ribs were removed, nerve intentially cut with each surgery being 6 weeks apart due to the severtiy of this surgery..At that time.. my sympathectomys were 'warrented' part of the operation, Dr. didn't blink an eye to insisting it had to be done and he did it.....today it makes me wonder if my problems with RSD started back then...let me know if you have any other questions..
