Since Feb 2019 I Have Been Suffering From Gastro Issues

Question : Since Feb 2019 I have been suffering from gastro issues it started with a dull nagging tummy pain during that month. Came on right after eating some greasy stir fry food. The following months at least once a month I had diarrhea and the same tummy pain. I went to the doctor in April and they told me I had gastroenteritis. Symptoms went away after treatment but came back in May and XXXXXXX like clockwork. I went back to the doctor in July and was told I had a Norovirus. This time they did more blood work and took stool samples and that resulted in them finally telling me I had food poisoning and mild wheat intolerance. They treated me and I no longer had diarrhea, but now I get a dull tummy pain, I burp more times in a day then I care to express, my stool movements are normal but the tummy pain is random and annoying. I drink ginger/peppermint tea, take peppermint pills, ginger drop and still end up feeling sick and bloated. To ease the pain working out helps because I notice once I work out the pain goes away sometimes. I also find if I work long hours and go a long time without eating I get extreme ill resulting in tummy pain, burping, vomiting, and cramps once I eat. It's so frustrating how one time it's they say its gastroenteritis, the next time its Norovirus, then food poisoning and wheat intolerance.
