You should definitely be tested for the H. pylori type of ulcer. It it's that type, it can be treated with antibiotics. It's a simple test where you breathe into a small balloon. Then swallow a mixture and 15 min. later breathe again into another balloon. Both are then sent to a lab to check for the H.pylori.
