I was wondering the same thing, I would only see TOS specialists about this now, don't waste time going to non TOS surgeons/specialists.
Check out TOS doc sticky thread -to see if any are close to your area.

The experts do these surgeries and do repairs all the time, you could even have internal scarring causing some of the problems. They can clean that up also.

I don't know how your posture is , perhaps some expert posture/body work might be helpful if you head/shoulders are forward or mid line, making some room for nerves/blood flow could help.
