S.B.
I had it done last year and it did hurt more then I expected it to. I did take a muscle relaxer before but it didn't seem to take. My advise would be what Justwed recommended, 800mg of Advil, at least, and then follow up w Tylenol. My friend had one done recently and her nurse practitioner told her to go drink margaritas beforehand. So she and I had lunch and margaritas and she said the pain wasn't too bad.
Good luck!!
