Stinky:
You are just 14 days past surgery? You should probably give a little more time with the rear area (though, I'm not sure what type of surgery you had...)
I would be more concerned with your stoma......at your last change, was your skin irritated (eg, red)?
Otherwise, I've had pains around my stoma I thought were skin/leak related, however, my home health nurse took a look and said my skin was fine....so, the pain is coming from the cut/wound/stiches/etc. around the stoma as gas/stool moves through.....also, how does your stoma look? Nice and bright pink? well moistened?
Thanks!
