HI!
I use a triaminic (sp.?) cream every day around the opening and then I put a slit in a round make up pad and slide it around and under the plastic base at the opening. It stays in place all day and protects the area. In any case there shouldn't be any leaking! Your doctor can take a picture of the inside placement of the tube to see if it is OK or not. Get in to see the doc. asap! I worry abut infection!
