I had an anal fistula. Nasty things, required two surgeries because the first one didn't work. I don't believe fistulas are straightforward surgeries. I had to go through an uncomfortable period while the surgeon let the symptoms develop. Sometimes giving the symptoms time to develop is necessary to pin down the problem. I'm sure the surgeon will have a clearer picture on Wednesday.

Is it connected to the SCC surgery or did the fistula develop separately?
