    What is a "fever blister"?

    I recently developed a very painful blister on my lip that is commonly called a "fever blister". So what is it, what causes it, and what is the best remedy to get rid of it?

    It is an infection of the lip by herpes simplex virus (HSV-1). An outbreak typically causes small blisters or sores on or around the mouth commonly known as cold sores or fever blisters. The sores typically heal within 2–3 weeks, but the herpes virus remains dormant in the facial nerves, following orofacial infection, periodically reactivating (in symptomatic people) to create sores in the same area of the mouth or face at the site of the original infection.

    A fever blister is caused from herpes virus, as stated by JThomp42, and does go dormant. Usual causes for flare up include stress, hormones, or an unbalance in amino acids. It is a see saw cause and effect. If arginine levels are high, then lysine will be low. As what happens when we eat to much chocolate, or other foods high in arginine. Coconut oil is high in l-lysine. It may be applied to the sore, and taken internally, to bring lysine levels up. L-lysine may also be taken in capsule form, 500mg twice a day, and l-lysine cream may be applied to sore. product link is … B00014E1HS

    To ease the pain of a fever blister...there are a few products on the market. Abbriva for starters. It doesn't do much to shorten the duration, but it does ease the pain.

    Fever blisters are caused by the herpes virus as previously stated by several people here. The trolls that keep voting down these appropriate and informed answers may be angry because they are suffering from them and don't want to be reminded of having the herpes virus in any way.

    This virus already infects an estimated 3 out of 5 people of ALL ages and can lie dormant for very long periods of time. This virus is easily passed when a person is shedding the cells containing the virus and this is NOT only when the person has visible blisters.

    Stress, illness, and sun exposure are some of the most common triggers for a fever blister. There are over the counter lip balms and creams that may help reduce the amount of time the fever blister is visible but the disease itself never goes just lies dormant.

    Lemon balm, Carmex, Abreva, are some popular choices for relief. Visiting a doctor is a good bet if you have fever blisters that won't go away or cause you an excessive amount of pain. They can prescribe medications for fever blisters and pain if needed.

    Fever blisters are a COMMON problem with a few options for relief. Once a person finds what works best for them, it's probably a good idea to keep it on hand for future use.
