Before they discovered my pinched nerves were a result of degenerative disc disease in my neck, they assumed I had carpel tunnel and a pinched ulnar nerve. I've had 2 separate EMG's, considering how bad the pain is the test is pretty easy in comparison. It's a bit scary with the needle part, but I'm a complete suck when it comes to needles and I did fine. It stings a bit but it really doesn't last too long. I found the electric pulses can 'bite' a bit.

Good luck! It's not that bad in comparison to other things I've had to endure with all this! You will do just fine.
