Hey Sweetie...
Boy, do I hear your frustration, and ya know the biggest question to me is...If these medical people have never had a stoma, how is it they can tell us whats O.K. and whats not!!!!! I have an ileostomy, and it has never, ever worked right. The reason I can say this is because this is my second time around with a stoma, and by comparing notes on the two...well, this one sucks!!! Your bump could be a hernia, does it hurt? Have they done any x-rays to see if it is tissue or possibly something stuck there? I would demand an appointment, and then don't leave till you have some clarity on what is going on! Is your stoma permenent? I do hope you find some relief, I know relief is something that only seems visible by the removal of the "evil" thing(stoma) Take care of you, and I will, for real, pray you to find some answers!
