I'm a 24 year old guy who recently had an anal abscess for the first time in my life almost a month ago. I went to see a specialist who drained the abscess and told me to see him again after 3 weeks to make sure that an anal fistula would not form. I went to see him a few days ago and just my luck, he said that he saw a fistula. Right after the removal of the abscess and up until now, there has been no pain. I've been able to work out and exercise and live normally.
My questions are:
1. Should I get an anal fistula surgery right away even if I am not experiencing pain right now? Will the fistula become bigger and lead to pain if I hold off on the surgery?
2. Should I have my doctor do an ultrasound first before going into the surgery to determine the scope of the fistula?
I'm afraid my life might turn 180 again if I go through the surgery considering I am not in any sort of pain right now. In most of what I've been reading in this forum, people get the fistulotomy because they are currently in pain. Is there anyone out there who went through the surgery feeling fine and just wanted to get rid of the fistula for sure? Any advice would be appreciated.
