I had a simarly difficult time getting dx'd with TOS. Plenty of docs told me that I didn't have it, but also said that they either didn't know what it was or didn't "believe" in it.

I contacted one of the surgeons listed in the list at the top of the forum to explain my predicament and ask him if he knew any docs in my area who do understand TOS. He saw me himself (and dx'd me) and then sent me to a neurologist he knew.

Check out the list and make some phone calls. Maybe they can still get WC to cover the appt if your case is not closed out yet

Good luck....i's a terrible situation to be in !
