Upper abdomen is where I used to have a pain quite often. The only relief I could find was forcing myself to burp. Only eased the pain but did help. Probably was just by chance that it helped.I've done tons of reading. My guess is Crohn's disease or gastroparesis. The pain is constant and has eliminated hunger pains. I very rarely actually feel hungry and when I do eat, I can't tell when I'm getting full. Accidentally getting my tummy overfull is a mistake I pay for. The pain is at it's worst then. It's mainly my upper mid abdomen. There are other pains that change as well. This has been going on since the 3rd week in July. I've just had it. It's making me cranky sometimes & I don't like me then.
