Sorry I don't have any experience with this. Just thought I would send a post. Hope you are feeling better these days.

(male) I've also had an appendectomy (08 Feb). I had pain after. But, I was told it was from my muscles and tissues needing time to heal. It took 6 months to do so (for the most part). My right side has pretty much healed (with the exception of the 4" scar). But, to add, a month ago, I noticed an abnormal looking "lump" within the left wall of my umbilical/naval area. Umbilical hernia? I'm wondering if the past surgery could have had anything to do with it.
