Dull pains on right side after eating or drinking that started after Bactrim. History of H-Pylori & other pathogens. Liver/Gall Bladder tests normal.

Pain of right side. You may have irritation of the gall bladder with wall thickening, small stones etc. I would monitor symptoms and if they persist, have the tests run again and perhaps an Ultrasound of the Right upper quadrant should be checked.
