The EMG is done with an itty, bitty needle. I'd like to say I hardly felt a thing but in contrast, the guy in the next room was screaming his head off.:-D
Oh, you should have heard this guy when he was getting juiced with the NCV exam! Wow. He was threatening to grab the electrodes and juice the NCV tech with them!
I believe the guy was just a big pansy. So, disregard any comments about any of this being painful. Have you ever stuck yourself with a sowing needle? (I hate to admit I sow...). Same kind of prickly feeling. To me, it only hurt when they jiggled the needle deep in my muscle tissue.
Hey, I took it well (so they said...)
If you are administered the NCV, just shout, "I'M ALIVE! I"M ALIVE!" when they hit you with the high voltage. The audience will get a real kick out of it! Trust me!
