I've had one too years ago, I was a teenager so more embarrassed than anything else! Didn't have any pain at any stage and was heavily sedated so don't really remember it at all.

Anyway went in for a very short bum op (done under general, I was under for less than 15 mins) and it was better IMMEDIATELY.
Marydean - one of my best friends had this done yesterday. She's been in agony for months (ever since having her son) with a fissure, I really, really hope she has the same result as you. She's called me in tears so many times, can't sit down to feed her son, can't leave the house most days.

Only drawback was she had to wean her DS because they use botox now (not sure how long ago your procedure was) and obviously this is a big no no for bubs. Heartbreaking decision for her but she just needed some quality of life back.
