I had two options:
1. general anesthesia
2. general + nerve block.
I was told the nerve block is like an epideral for the leg only, that helps reduce pain for some time after surgery.
The block is an elective procedure, which I assumed would cost me extra money, so I didn't do it, because I'm cheap.
I had no pain after the surgery, probably because of the percocet pain killer I was on, and whatever they put in the IV.
