Cold Sores

A cold sore on the lip is a most distressing condition for many patients as it is so prominently visible on the face. In fact, the cold sore is caused by a type of herpes virus which lives in the nervous and periodically bursts out on the skin causing a blistering lesion that then scabs. Dr Grant Blashki talks about the causes of cold sores, what you can do to treat them and also how to prevent them.
