I would say for you to give them a call. If it was me 10 years ago and I knew about this proceedure knowing what I do today about MS I would have done it. Your problem is going to be insurance. You are not going to have much luck from that standpoint. The good thing for you is you know about this and if your MS does progress you can jump on this then. Any damage that you might have could most likely be reversed.
Give them a call. They will be more than happy to be very straight forward with you.
