I think it depends on pain thresholds and if there is something wrong. See, when I had the nct, it wasn't fun, but didn't hurt. When the emg started, it was very uncomfortable, and felt like everything was cramping, but wasn't painful, until they put the needle into my left shoulder. I started to cry immediately. See, I have a pinched nerve there and it was very painful. So, that is an example from my point of view. There are many factors that could cause it to be more painful-I don't think pain meds are good for before the test, but I don't know. Def after if you hurt. These are all things you should discuss w/your doc
I am having another done next month (last was in NOv), and I am not bothered by it, though I am not ready to cry from pain either. But, gotta do what I gotta do.
