Maybe I am presuming too much, but I am guessing that a doctor told you that you have an ulcer. At that point it was their responsibility to inform you how to handle this problem, and answer all of these questions. I suggest writing these all down, and going back to your doctor, and demanding answers.
Many doctors tend to only give you information when you ask direct questions. You have two options. Either make the doctor do his job, or if you don't feel comfortable giving a doctor orders, find one who does this without prompting. This should be automatic, but sadly is not.
I always find it disturbing when people with health issues find demanding a doctor do their job more frightening than asking complete strangers with no training for answers. What else are doctors for?
