Cold sores are groups of painful, fluid-filled blisters (often called fever blisters). These unsightly sores usually erupt on the lips, and sometimes on skin around the lips. Clusters of small blisters may also occur on the gum tissue near the teeth and/or on the bony roof of the mouth.
Cold sores usually heal in about a week. Once the blister breaks, an unsightly scab forms.
