My suggestion for helping skin erosion and aiding in healing rashes is this. On the weekend, stay the fuck inside. Take your bag the fuck off. Walk around with toilet paper around your stoma, secured with tape if need be, but I'm not a high out-putter and my output isn't liquidy, so I don't have too much probs with this. My reasoning for this is the rash and the infection needs to breaaaathe. The skin is sick of being imprisoned under strips of wax and adhesives and it yearns for the cool kiss of a summer brease upon its malformed infected face. Also, I wipe Destin on my eroding skin and use Aloe vera gelly on the rashy part, but Bacitracin Zinc Ointment USP is always a good choice. this isn't just me advising this. I've dug around through ostomy forums for this info, and this works.
As I still don't have too many bags to be using recklessly, I've only gone de-bagged twice, but I think I'm starting to see the difference in the overall healing and happiness levels of my epidermis.
