Littlehud,
Good luck with your surgery. I had the same thing done a while back. Since I'm a nurse, I decided I wanted the anesthesiologist I worked with every day to do my anesthesia. He wanted to do a nerve block (in addition to the regular anesthesia). My orthopedic surgeon didn't do blocks, he uses pain balls. Well, I told them to suck it up and work together 'cause I wanted BOTH! So they did, and it worked out great!
Good luck to you!!!
