Thank you to everyone who responded. I emailed the information to my parents, who then gave it to the orthepedic surgeon. He was very responsive to my concerns. He and I emailed a few times today, in addition to my father meeting with him today again. The surgery to correct the Charcot's Foot is tomorrow and we will keep our fingers crossed that the different types of anasthesia will keep the RSD away. I will keep you posted. I feel much better about the procedure now.
