I've had an EMG and nerve conductivity test on the nerves from my lower back to legs. I have a few pinched nerves that aren't causing pain right now, so we left it alone. The test I had required very thin needles to be inserted into the nerve area. They are like acupuncture needles, very, very fine. It was uncomfortable and not painful for me, but I have a high tolerance. I've had a cyst removed from an ovary, endometrial tissue burnt off and a DNC at that time. I didn't take any pain meds once I left the hospital last October and a Trans Vaganial Tape done in April and no pain meds after the hospital. I took advil, but nothing else. Everyone's pain limitations are varied. I saw a girl on YouTube taking off one of those nose strips. You would have thought that you were cutting her open. She had a very low threshold for pain.
