Ulcers are sores that are slow to heal or keep returning. They can take many forms and can appear both on the inside and the outside of your body.
They can be found on places of your body you can see, such as a leg ulcer found on the skin, or in places you can’t see, such as a peptic ulcer in the lining of your stomach or upper intestine. From your eye to your foot, you can get them just about anywhere on your body.
Injuries, diseases, and infections can cause them. What they look like depends on where you have them and how you got them. While some go away on their own, others cause serious problems if you don’t treat them.
