Yeah, the one I was reading about, they insert needles in various places in your legs (and arms in some cases) and ask you to flex your muscle. Some patients reported that it was so painful that the doctor had to stop the procedure (they used the word "excruciating"). Then there is the pain afterward from bruising, etc. I think you may have had a nerve conduction test, with those electrode thingies taped to you. No matter what, I hate getting poked and prodded!
