At this point, I would go to Denver and see two of the three top docs there and get a definitive diagnosis. They see TOS so constantly and so often, that for me, that would stop the merry-go-round, which I was also on, here in So. Cal. And EMG is only worth the skill of the person who does it. Dr. Togut says EMGs aren't even made to test for TOS, the scientific reasons behind that statement are too hard for me to understand but DiMarie has posted it before. So I'd want to be seen, touched and "decided" by one of the top docs.
