This sounds serious, and the only thing you can keep doing is pestering a doctor.
I know how you feel though-I was in pain for years, and doctor's kept saying the pain in my legs and arms was all psychological, they did a blood test one day however, and realised that it wasn't, and was actually quite serious. I don't want too worry you, but sometimes doctor's do get it wrong, and you have too hit them over the head a few milion times too make them take notice.
Do you have a GP or anything like that? Sometimes ER dismiss things, as it's for emergancy patients, they seem to not take as much notice too the littler cases. Well, at leats this is what it is like in the UK.
Stomach pain, could be something simple, annoyingly it's not as simple too try and get checked out properly.
Good luck, and hope the pain goes away soon
