I have had problems like yours off and on for several years. Here are some things that help me:
1 Eat right. Lots of fiber. You do NOT want to be constipated. Straining hard trying to get a turd out is almost always part of why you get a flare up.
2. Take hot baths as hot as you can stand. This really helps.
3. Sit on a pillow at your desk or wherever when you can.
4. Don't read on the toilet. Sit down, do your business, and standc up. Lingering on the pot really aggravates the situation.
A word about surgery: it takes a while to recover. I could shit comfortably after a month or so. It took me several months to get to where I could comfortably bottom. Even after a year or two, a bout of constipation could reinjure the scar. Now 10 years later, I seem to have it all behind me
Hope you feel better soon!
