Don't stress, it's certainly not my idea of a fun time but it's certainly not painful. You get "zapped" which feels quite uncomfortable, but it's soon over and none the worse for wear. Even the needle studies aren't that bad. I too have unusual, undefined & undiagnosed neuropathy and have NC studies every few months. I've certainly never felt like screaming! When you get home have some paracetamol or pain med of choice if you feel you need to.

Good luck!
