I've read good and bad about ablation that was done surgically. However, the newer techniques using cryo seem to have good success rates. Problem is finding a doctor who believes in this as most doctors that I mention this to seem to refer to the cryo techniques that were used decades ago which had little success. However, in either case one is always concerned about techniques that could affect the normal function of the nerve or nerve endings as if something went wrong the pain would get worse. So we are very cautious in heading in these directions.
