Hey Scott,

Best of luck with your diagnosis !! Everybody kinda touched on all the possibilities - as Gary says, there's a "non-invasive" test to check the nerves between specific points. Yes, "non-invasive" - but you might want to hang on to something when they turn the electricity on as your arm will do things entirely out of your control. I've had carpal tunnel syndrome for many years. It goes and comes, but it's never been bad enough that I wanted to have surgery. There are several non-surgical treatments now days. One is light therapy (using light-emitting diodes - at different frequencies). I can usually tell when it flares up by the fact that my "pinky" finger and the one next to it begin to get numb. Again, good luck with the situation.
