Anal fistula surgery: what to expect?

I’m looking for the lowdown on fistula surgery since I’ve got it coming up soon. Is this just a routine procedure? What’s the damage cost-wise? Also, what kind of testing am I looking at beforehand? How long am I stuck in the hospital, and how much downtime should I plan for during recovery?

If it’s just clean on the gums, it isn't a big deal
you should just head straight home

The only rule is you can't eat or drink anything hot. I made the mistake of having something lukewarm on the first day and my face swelled up immediately 😁
Plus, you can't really open your mouth much on that side, so smiling is a struggle 😁
But honestly, there's no pain
