I would avoid foods that are acidic like tomatoes and citrus fruits Did the doctor tell you that you had reflux
I would see a physician and have a workup done to see if you have a reflux problem or some type of esophageal issue.
You say you've been told your stomach is inflamed? How was that determined? Ultrasound, endoscopy, upper GI, xray or ???? Were you prescribed anything?
Wishing you best of luck!
