Oh Rosa! I'm so angry for you! Your doctor sounds like a real donk! I'm also a bit puzzled about why he would talk about putting in a seton. Those are usually for high fistulas. But if you got your fistula from the LIS incision, like I did, then it is most likely a very low, superficial fistula that can be taken care of with a simple surgery to lay it open (a fistulotomy). That's what my doc did and it worked like a charm. The fistulotomy was not fun, but it wasn't any worse than the LIS (and was actually easier, in my case). I think you should try to see another surgeon and get a second opinion. If you have a fistula, you will need surgery to fix it. I also don't understand why your doctor is putting you on antibiotics. ABs won't cure the fistula, and docs don't even use them very often for anal abcesses either, since they don't reach the abscess pocket - that's why doctors will drain an anal abscess.
I'm really sorry you are going through all this. But please don't feel too bad - up to 50% of abscesses will develop into a fistula and there isn't anything you did or didn't do to cause that - it's just bad luck, and I really sympathize! I know how you feel! I had a good cry too when I learned I had a fistula. I don't understand why your doctor wouldn't tell you. I really think seeing another doctor is a good idea.
Hang in there, Rosa! You can get this fixed. Just get assertive. You WILL heal!
