I would only add to what both PaulB and Christine have said about a possible leak. We have just dealt with a similar situation. John went and saw a stoma-therapist who recommended putting a barrier cream like Pro Shield to stop the stomach acid from burning the skin. John also got antibiotics from his GP which cleared up the infection. Now five times a day he does a saline soak, then he lets it air dry for a few minutes (the intervention radiologist even suggested using a hair drier to dry it -- apparently dryness is the key). He then puts a bit of anti-biotic cream followed by the barrier cream and the dressing. In only four days it went from burning, raw and bleeding to properly healed skin. The intervention radiologist saw him today and was pleased. Hope this helps.
