It is possible that your discomfort is stemming from the presence of
gallstonesAcute cholecystitis (gallstones)
Gallstones
Gallstones, cholangiogram
Kidney cyst with gallstones, ct scan. If this is suspected, removing the gallbladder is indicated.
Other possibilities can be inflammation of the upper digestive tract, or an ulcer.
The upper GI series is a reasonable approach, but you may want to consider an upper endoscopy, which can give a more comprehensive evaluation of these possibilities.
More specialized testing with a 24-hr pH study or gastric emptying scans can be considered as well if the initial workup is non-revealing.
I would discuss these options with your personal physician, and consider a referral with a gastroenterologist.
Followup with your personal physician is essential.
