An ulcer is a sore, open place where the surface has broken down and will not close up quickly. It can be on your skin — an ulcer on the leg of someone whose blood does not flow well — or inside your body, most commonly in the stomach or the first part of the small intestine, where doctors call it a stomach ulcer or a peptic ulcer. It can bleed, and it usually hurts.
