I also suffer from thorasic pain. You are very lucky to find a doctor that shows any interest in thorasic surgery. Every doctor I went to would not touch it. I have tried chiropractic for my thorasic problems with very temporary results. It never really helped with the pain but it did help with the stiffness. I was injured in 98 and I have found that as the years go on I am becomeing very ridgid and stiff. The last time I went to the chiro, about 2 years ago, he really hurt me and I took about 2 months to get back to where I am now. Arthritic changes have made it very tender and painful.
Good luck on your decision for back surgery and keep us posted.
