Welcome to Neuro Talk. You found a good site to investigate for TOS. I wish you all the best in your coming surgery. Post any questions you have, or concerns. There are alot of individuals on Neuro Talk, who have the same condition as you do. I know you are nervous. We all get that way when we face surgery. I came here for much the same reason you did. For some information and comfort facing a big surgery. I hope alot of other welcome you here, and that this community can help you through what is ahead for you. Be good to yourself. I also hope you have a good support team in your corner. NT will be here for you too. ginnie
