My experience post op and suggestions are from Dr. Brassard, and not sure if these are the same for everyone. Early on, following surgery, I kept these in mind:
1. After showering and sitz baths, always, always air dry
2. When I slept at night, never wore underwear as sweat or humidity is bad
3. Never use scented pads or other products. In fact, at home, I use unscented dryer sheets
4. Douching was very important early on, and it's recommended to douche at least once a week as it gets rid of dead skin
Just my thoughts
