Hello. Ever since I was in middle school ( 20 years old now) when i got a severe stomach virus for 2 weeks(doctors didnt know what was wrong with me. I had severe stomach aches, possible acid reflux , and vomiting/ diarrhea at the exact same time) I have had often sharp stomach pains, tightening throat everyday( still breath normally), stomach acid and recently-eaten- food comes up my throats, and less frequent than normal bowel movements. I don t know what it could be and I was wondering if there is something to explain or help it. Please help in any way you can.
