I would advise you to make sure you get a second opinion with another neuro. Also it is important to TRUST and LIKE the person doing the surgery. If you have any doubts, look up his records. I know you are in pain, but that second and even third opinion is so very important. Get your records and your own MRI, find out exactly what is going on before you agree to surgery. If this is recommended, ask what the surgeon is planning to do, look up the proceedure before hand.
I do wish you all the best. Hope a good resolution happens for you. Not to make you frightened, ....My second surgery was wonderful, and I have good resolution 3 years later. My pain is not that bad, and something I can live with. Keep in touch, and let us know how it goes. ginnie
