I had that painful heartburn 19 years back until my Dr suggests that I see a dietician who took my blood tests to lab to see which blood group do I belong to and which food to eat and which not to eat. Only to find that I was not supposed to eat corn and I was not aware. Ever since that time, I follow my diet and no more ulcers. 20years now without pap and anything with corn.
