Cold sores are a very common illness caused by the herpes simplex virus (HSV). The disorder is characterised by groups of fluid-filled blisters which appear on red swollen areas of the skin or on the mucous membranes. The areas can be tender and painful. The blisters heal without scarring but have a tendency to recur. 1  There are two types of herpes simplex virus.  HSV-1, which is the most common type, usually causes cold sores (oral herpes). HSV-2 usually causes genital herpes. But both types can infect any area of the skin or mucous membranes.
