Cold Sore Treatment

Cold sores are painful blisters on or around the lips and mouth. Cold sores are caused by the herpes simplex virus (HSV). The herpes simplex virus type 1 (HSV-1) is most often associated with cold sores, though the herpes simplex virus type 2 (HSV-2), which causes genital herpes, can also cause cold sores. There is no cure for cold sores or the herpes simplex virus.

Treatment for cold sores often involves over-the-counter or prescribed medications to ease discomfort as the blisters heal. In some cases, certain ointments applied on the cold sores or oral antiviral medications such as Valtrex can speed healing by up to two days or prevent future outbreaks.WebMD: Cold Sores - Topic Overview MayoClinic.com: Cold Sore: Treatments and Drugs

Red, painful, fluid-filled blisters will begin to form around or on the lips or mouth area. Some people will experience a tingling sensation or pain in the area up to two days before the outbreak. Within a few days, the blisters will begin to break and ooze, before crusting over and eventually healing.WebMD: Cold Sores - Topic Overview
