• Fever blisters, also called cold sores, are caused by herpes simplex virus type 1. They usually occur on your lip and can be very unattractive, to the point where you may want to pop them. This is not a good idea, though, for a number of reasons.

    Do Not Pop Blister

    Do not pop the fever blister, as it can spread the virus and lead to infection and possibly scarring. There are many other ways to treat a fever blister that don't create additional problems.

    Cool the Area

    As the fever blister begins to appear, apply cold to the spot. Freeze a spoon and press it against the blister (but not too hard). Apply as long as you can tolerate it and then remove it. Then apply ice that you've put in a plastic bag. This repeat freezing will cause the swelling to go down. Apply cold for 30 minutes or so.

    Vitamins and Diet

    Taking a large number of vitamins and following a stricter diet will help existing cold sores heal and keep them from coming up as often. Taking vitamins like E, C and zinc can help prevent cold sores, as can a diet that minimizes oils and fats. Vitamins and a good diet help boost your immune system, and these help keep fever blisters at bay.

    Avoid Contact

    When you have a fever blister, avoid direct contact with other people who do not have the herpes virus. It's best to avoid kissing.
