Cold sore: A cold sore involves the border areas between the skin and mucous membrane and is often mistaken for a canker sore which occurs only on the mucous membrane and not the skin. It is caused by hsvi and can be triggered by sun exposure, stress, another viral illness etc. If severe, your doctor can prescribe an anti-viral drug to hasten the healing.
