How long has it been since surgery?
The good thing is, since you've had the surgery, any damage you did should heal up faster. I'd do whatever you did before surgery for relief; sit in the bath, or on a heating pad, use some ointment, take some ibuprofen, drink extra water, and/or try taking a stool softener like Miralax for a few days at least until it feels better.
At least it didn't bleed, I HATE the bleeding!
