Excess body heat

You should really consult with both a western doctor for traditional tests and an acupuncturist in your area. But generally, if after food you have an intense burning feeling, it’s possible that you have an ulcer. Obviously, if you know the triggers - don’t eat those foods and that may give it some time to heal. From the western side I would likely recommend you get tested for h pylori (stool and/or breath). See someone locally and they should be able to help you.
