Sorry to hear you may be heading for more surgery.

Are you able to distinguish the pain of the osteophytes hitting C4-5, 5-6, 6-7 from the pain of any residual TOS problems since your TOS surgery? Would you be able to use the same surgeon as you did for your TOS surgery? Good luck with your visit to the neuro! Will be interested in hearing what he says.
Hugs to you.
