acidrefluxman, I am not a doctor and I am not an expert in anyone's body except my own. Referred pain is a common issue, and since the vegus nerve runs right through the URQ I've seen it noted as a potential source of referred pain from elsewhere in the abdomen.
The duodenum extends from the bottom of the stomach toward the gallbladder. People can have duodenal ulcers. It is a normal part of the endoscopy to look at the duodenum, so if you've had a few endoscopes, I'd be confident that your GI has examined it visually and taken biopsies there. It might be worth your time to review that information when you meet next.
Crohn's can be challenging to diagnose, but your GI is the one who can discuss all the symptoms with you. From what you've said here, normal BMs & normal bloodwork does not point to an IBD. My concerns re:Crohn's and my URQ pain is a potential stricture, either in my small bowel or transverse colon. I've had a stricture in my esophagus, which was not fun, and since my URQ pain seems to be related to bowel fullness, I suspect that somewhere along the line I've had a narrowing of my bowel. Since you've had a bunch of imaging studies and no one's identified any structural abnormalities, I'd check that worry off your list.
