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.
People frequently use the terms canker sore and cold sore synomously, but they are not the same thing. Although canker sores and cold sores may appear the same at first glance, there are distinctive differences. Canker sores are caused by damage to the mouth, foods, or an underlying disease, while cold sores are caused by the herpes virus. Eventually, cold sores become crusted over while canker sores simply go away.
