There is not any guarantee on successful rates as there is not many patients he had follow up with him after care.The surgery is not a cure but more of a means to reduce the symptoms. I have talked to others he has helped and all are satisfied and glad they did the surgery. He is highly recommended. Its not really the money issue. I have been worried about if it is the right move for my wife to have another surgery to correct a mistake. I know she is miserable but I cannot tell how much is depression and how much is physical. I am hoping the therapy she is getting can help.
