An ulcer is a sore (whether bleeding or not in the digestive track. So, if you vomiting blood, then yes you technically have an ulcer. The question is, what color is the blood? If it is a dark red... Even black color, this means you have an ulcer in your stomach that needs immediate medical attention! Could result in abdominal infections and worse! If it is a brighter red (almost the same color as from a finger cut) then it would be a lesion/tear/ulcer in your esophaugus (sp?) caused by your continued heaving. The good news is it is repairable and not considered life threatening, the bad news? Hurts badly. My doctor suggested prilosec and other acid reducers to heal my esophgial ulcer.
