Lori,
If it's going to be like mine there's a little bit of pain involved. I don't want to be the messenger of bad news just being honest.
The test, if it's the one I'm thinking of, involves the neurologist using needles wired to a computer with the purpose is to locate some nerves and short them out and others to force a slight muscular reaction.
Imagine being stuck by a needle and the neurologist wiggles it slightly around locating certain nerves. If you can imagine that then you'll know what you're in for. It won't take long. I hope I didn't scare you...
