Get tested for the bacterial believed plays a big part in causing ulcers - helicobacter pylori. You can heal your ulcer by avoiding caffeine, greasy foods, nicotine, alcohol and for some people - spicy foods also. Also I have heard that cabbage juice heals ulcers - but I don't know if that is raw (as made with a juicer) or if it can be cooked with a little chicken broth or something. Leave the milk alone. Good luck.
