I had a vasectomy about three years ago. Very smooth, no problems. I had the local anasthetic and was awake during the entire thing. Other than the needle, there were a few twinges of pain and I could feel the tugging on the vas deferens (sp?). I got a prescription for a pain killer, but I never used it. A couple of advil, maybe. I rode the bus home from my Friday appt. I rested over the weekend, took my two advil, and went back to work on Monday. I sit at a desk all day. I stayed off my bicycle for two weeks, but after that no problems.
I don't know how much the price of things have changed. I paid a $300 deductible for my insurance, but I think the total actual cost was around 1500-2000. Perhaps because this urologist preferred to do the procedure in an actual surgery room in the hospital instead of in his office.
I agree with mouthy about getting the follow up checks done to make sure the sperm count is zero. If you're going to do it, follow through, and make sure everything was successful.
