This will be my first mothering post that is kind of funny. I had a small case of hemorrhoids with my first and I used Witch Hazel (found in drug stores and health food stores) on makeup pads. Everytime I wiped i would finish with a soked pad. They never got very bad. If I felt sensitive I would just use them again. Good luck.
I never really used anything on mine, just gave them a break by using wet wipes (the flushable kind they market for toddlers) instead of TP when they were bothering me, and skipped my prenatal vit every other day so the iron wouldn't constipate me so badly.
