    Fever Blisters and Cold Sores
    avatar
    Susan Evans, MD posted:
    Dear Readers,

    Recently I've had a number of questions from my patients about fever blisters (also known as cold sores). Both problems are actually the same thing and are caused by the herpes simplex virus. Once you become infected with this virus, it will be with you for life. This means that you are susceptible to periodic outbreaks throughout your life.

    This resource will help to answer questions you have about what causes fever blisters/cold sores, how to avoid it if you don't have them, how to manage an outbreak and how to help prevent future outbreaks. I'm sure you will find this information helpful.

    Best,

    Dr. Evans
