After my surgery, the doc gave me Tylenol with Codeine, which did nothing for the pain. The following week he switched me to Vicodin, which also did not help. Finally, he changed me to Darvocet which was a real improvement. I tend to be shy about asking any doc for stronger pain meds, lest he/she think I am some kind of junkie, but in retrospect, I should have been more assertive. Good luck with your surgery.
