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.
Cold sores are inflamed blisters in or near the mouth and lips. A herpes virus causes cold sores. Herpes simplex virus type 1 (HSV-1) causes about 80% of cold sores while herpes simplex virus type 2 (HSV-2) causes about 20%. Cold sores are often confused with canker sores. Canker sores are not caused by herpes viruses, are not contagious, and occur mainly inside the mouth, not on the surface of the lips.
