What is it?
Cold sores are painful sores that usually occur around the lips. They are caused by the herpes simplex virus (HSV), and may appear during times of stress or illness, or in exposure to bright sunlight. Cold sores usually start as a tingling sensation, then burst into sores, and heal over in seven to ten days. Unfortunately, cold sores cannot be cured, but they can be prevented by taking a medicine called acyclovir.
