I live in England and as far as I am aware all the big hospitals have a stoma nurse. It seems strange that your hospital doesnt have one because they obviously need one for people like yourself. It doesnt seem right or fair does it?
As for the eakin seals.... I think its a case of what suits one wont suit another person. I have heard of some people breaking the eakin in half and stretching just the one piece around the stoma, others use the whole thing. Yes it does need to fit quite snug up to the stoma,but again I think some people put it on first,but others fit it to the bag first and then apply. It's what works for you realy.
