To the OP:
Yes! I had the most horrific pain where my stoma was and now I have a hernia. As for the pain, it was due to adhesions or scar tissue. It caused ascites and I had 1100cc of fluid sucked out of me. It came back and the pain continued, so my surgeon cut me open and fixed me up. He inserted a mesh. So far so good.
I will have another surgery next month to fix the hernia. And another mesh. It feels like a never ending battle. Unfortunately, I still feel a lot of pain when not taking meds. The only meds that really address it is Suboxone. Better than regular pain meds. Except it is now more of a dull, throbbing pain vs sharp pain that feels like shards of glass.
I don't know of other options other than surgery. Good luck.
