Cold sores are small, painful, fluid-filled blisters or sores that appear on the lips, mouth, or nose that are caused by a virus. The sores can be
painful and usually last a few days. Unlike most viral infections, the cold sore
virus is not completely eliminated by the body defenses. For this reason, cold
sores often recur.
