I have upper right abdominal burning (not pain exactly). This developed 5 months ago. That time I had endoscopy done and h.pylori infection was detected at duodenum. I used antibiotics and it is gone. Now it came again. 8 months ago I had ultrasound scan for completely different reason. Gall bladder was normal but mild fatty liver was detected. Now my problem could be gall bladder or h.pylori one? Can gallstones be developed and cause pain in 3 to 8 months? I have constipation as well and hence causing lots of gas.
