i really did have no major problems...it was easier than what I thought / expected from the blogs..and more or less what my CRS told me prior to the surgery...Some minor ache during the first two days. Just for precautionary purposes I got a depon prior to sleep during the the first three post op days.
I did not have any fistulotomy at all though (no partial fist/tomy either). Only draining seton. The next day I went for a soft jog, and the day after for half and hour basketball with my kids (half an hour but intense!)
After 10 days it's really no problem at all. I am on holidays and I have been exercising every day (like I did prior to the surgery). I've been swimming on the beach as well
Good luck with your surgery! So far the surgery aspect was quite easy for me (especially with the aneasthesia: it relaxes you and you have a great sleep!).
