hey Trace! i had the same thing happening to me couple weeks ago - i was at work and at about 2 pm i felt the stinging feeling and it wasn't only stinging, but was really hurting. i went to the b/r and saw that there was a bulge of thick stools sitting on my stoma. gosh, just like you i figured it should just slide down soon. but it didn't. the stinging went on untill i went home at around 5 pm, and just on my way home i felt a warm feeling spreading on my abdomen (well luckily my work is only a 10 mins walk from home). when i got home i saw the wafer was off of my skin too and the stools was all over me and my cloths....
i immediately hit the shower, took all the appliance off and i also noticed that my stoma has gotten so flat at the same level as my skin, but only the lower part. the upper part was still sticking out as usual. but i got so freaked out, b/c just 2 days earlier i had the incident of pushing on my stoma - remember that?? when i posted that i thought i ruined my stoma?? well i got really freaked out and called the stoma nurse and histerically told him all that has happened and that i thought i ruined my stoma. i also had a bit of a skin burn just under the flat part of my stoma.
but i must mention that all of that leak happened b/c i was wearing hollister's appliance - i had many troubles before with hollister, that's why i shifted to coloplast. for me hollister holds for about 2 days, 3 max. with coloplast the wafer holds much better and much longer - up to a week.
the lower part of my stoma is flat now, so i started with convex too, i think it helps.
