Yes: Cold sores and fever blisters are terms people use to describe a viral infection which usually affects the lips. The most common cause is by the hsv1 virus. They can be treated with anti-viral medications. An episode typically lasts about 10-15 days.

Yes: Cold sores, sometimes called fever blisters, are groups of small blisters on the lip and around the mouth.
