Yeah, I had one of those nerve conductivity tests and they suck. After about the 6th or 7th shock you're ready to beat the crap out of the person zapping you. Hopefully they get it solved for you. Just a bit of info, Mike; I was having a lot of elbow pain and numbness in my hand a few years ago and had two doctors tell me I needed surgery. I ended up having a chiropractor look at it and within 3 weeks she had me pain and numbness free. Not saying that's your issue but it could be worth looking at. I always thought of chiropractic medicine as voodoo science but it made a believer out of me.
