Cold sores are a cluster of blisters that first appear clear then become cloudy. First infection may be inside the mouth, but cold sores generally appear outside the mouth on the lips. Canker sores are gray or white sores surrounded by a red inflamed area.old sores typically result from a viral infection called herpes simplex virus (HSV). Cold sore blisters can occur on many different parts of the body but are most common on or around the lips, cheeks, or nose and also (on rare occasions) in the eye.
A cold sore often begins as several tiny blisters that eventually form one larger sore. They appear most often on the lips and face. In contrast, canker sores usually travel alone. And unlike a sore caused by the herpes virus, a canker sore is not contagious. A canker sore has a yellow or white-gray center with a well-defined red border. It generally measures three to five millimeters in diameter and is usually located on the inside of the lip or cheek or, less commonly, on the tongue.
