Fever blister, also called oral herpes or herpes simplex type 1, are groups of uncomfortable, fluid-filled blisters. Also, cold sores typically appear outside your mouth - usually under your nose, around your lips, or under your chin - but canker sores appear inside your mouth. A canker sore is not the like a fever blister. Canker sores are a common form of mouth abscess. Canker sores frequently appear on the inner surface of the cheeks and lips, tongue, upper surface of the mouth, and the base of the gums. Unlike cold sores, canker sores do not occur on the surface area of your lips and they aren't transmittable. Most canker sores go away by themselves in a week or two. Most canker sores are oblong or round with a white or yellow center and a red border. You might see a tingling or melting sensation a day or 2 before the sores in fact show up.
