Hi Paulie, Jack was one of the ones with a positive experience with acupuncture but as everyone has told you there is NO medical evidence either way. It was probably the 8th or 9th visit that occurred. We were told it either works or it doesn't. make your own judgment on that one.
Jack never had any discomfort or pulling on the jaw from acupuncture. I'd get the jaw checked out. Do you have any trismus? That might cause a sensation like you're describing.
Our rule of thumb is we get it all checked out no matter how small it seems - this way we don't agonize over it more than we need to.
Regards JoAnne
