Thanks for finding EmpowHer, and for your question.
From what I've found online (google search on the condition), it sounds like the lining of your stomach is irritated at the upper curvature portion of the organ.
Did your doctor perform a biopsy to find out what is causing the irritation? Do you have celiac disease? These things were often related to entries I found online. Are receiving ongoing treatment from your doctor? Are you taking any medication for the condition? Has your doctor suggested restricting your diet at all?
Don't be afraid to ask your doctor to define those terms in ways you can understand. Be your own best advocate. Hope this information helps.
