There was no pain when it actually happened. I've a couple, there was one above the belly button that most likely occurred early on while I was still healing, for the longest time it would hurt whenever I coughed.
The parastomal hernia which is the one that is causing my all of the issues just developed, but it probably started during my recovery period, I was in pain anyway so it was most likely masked by that. I found out about them the first time I went to the hospital for an obstruction, which was abut a year or so after my disembowelling. I had always been bulgey round the stoma, I assumed it was because I am a fat guy, and that was how it was supposed to look.
