Cold Sores

Cold sores are very common and quite contagious. Sometimes referred to as fever blisters, cold sores can be caused by the herpes simplex1 virus (HSV-1). They can appear as a single blister or cluster of them, often recurring in the same location, including on and around the lips, nose, chin or cheeks. Cold sores are often confused with canker sores, but canker sores are actually sores or ulcers that occur inside your mouth, and are not contagious. There are a number of treatment options available for this skin condition.
