Just make sure they give you enough pain meds. I had an umbilical hernia done a decade or so ago. They started and I was fine at first. Then I started feeling them cutting. So they gave me more local anesthetic and started again. Then I felt pain again. Third time was the charm. I don't remember how long it took to heal, but I don't recall it being a big deal.
I haven't seen a beatin' like that since somebody stuck a banana in my pants and turned a monkey loose.
