Thanks for the comments. I am 35 years old.
Pain, which goes around, and bulge and belching...it sounds as a gas. In your case the gas may come both from the stomach and small intestine.
Have a breath test for H. pylori and
another test for small intestinal bacterial overgrowth (SIBO).
Burning sensation in the rectum...hm, regarding you have normal bowels, internal hemorrhoids sound most likely. How old are you?
