Hello Doctor, Since A Year I Have This Pain Right

Hello doctor, since a year I have this pain right in the upper middle of my stomach which is also felt exactly on back of it. It triggers after having honey always. But last month I had some fried okra and ooops I got pain. I went to the Badger and the doctor diagnosed an ulcer in stomach so did my gp. Please help me how exactly the doctors are right in their diagnosis. They have prescribed me antibiotics for 3 months. Thnx alot
