sorry, i'm not a W/C case, but others here are... what state are you in? there is a W/C forum here on neurotalk which you might find helpful.
i CAN tell you that what that doctor did to you is just plain WRONG. i am not an attorney but it sure sounds actionable to me. he had absolutely no right to do that to your arm, and i am sorry that happened to you. i can only imagine the immediate, sheer agony that must have caused you, not to mention the aftermath. what a d-ickhead!
shameless! if i were you, i would seek out the advice of a top W/C attorney, one that is not only well-versed in medical malpractice (for that is what you are describing, if i ever did hear of any examples my friend... that is one!

) but also who knows something about and has handled and prevailed in work-related TOS cases.
i think you said you were near PA, is that right? if so, that is very good news, for reasons which will become clear to you soon enough. but the lawyer should be admitted to the bar in the state in which you filed your W/C case. was that NJ or PA?
also, didn't mean to ignore you on your question re the EMG measurements. i simply don't know the answer. i don't recall that coming up in connection with any EMG or NCV study i've ever had done. here's a good link for you though (and maybe a good doc, if you can get him OK'd - go see dr. fried he's very highly spoken of by other forum members and could go over those EMG results with you, explain them to you better than any of us could, that is for sure!

i'm glad the pain and other sx did calm down after the doctor pulled your arm straight up like that. did he think you were faking it or something? whatever happened to "first do no harm?"
i'm sorry but i find that behavior unconscionable. was there a nurse in the room? any witnesses? this man could have worsened your original injury, my friend. worse, he is in a position to know that.
get an attorney. there are ways to find out who the best guys are if you are interested. i think your rights and your person have been violated here, or i wouldn't say anything. now that i'm thinking about it, it might even be a separate claim; i don't know. also, FYI, under this type of legal arrangement the attorney usually works for a fee that is paid out of the final award or settlement of your case, so the upfront costs are zero or close to it...
i don't mean to upset you. we are here to help.
