What Causes Fever Blisters

Fever blisters, also known as cold sores, can be both painful and embarrassing. What causes fever blisters is typically the Herpes Simplex Virus.

So, if you’d like to learn a bit more about how you can develop cold sores, as well as how to prevent them, then you’ve come to the right place.

Fever blisters caused by HSV.

Herpes Simplex Virus is what causes fever blisters.  There are two types of HSV: HSV-1 and HSV-2, though typically the second form is more commonly linked to genital herpes, rather than oral. The virus is usually contracted prior to ten years of age, though it can remain dormant for an extended period of time. Some who have the virus never even know that they have it, with only around 10% of its sufferers actually experiencing outbreaks of cold sores. During one of these outbreaks, red and swollen blisters will erupt around or on the lips, and sometimes even in various other parts of the body. These sores can leak fluid in certain instances, which will result in a crust forming over the affected site. The outbreaks will typically clear up within a matter of a few days, but can last for as long as 2 weeks on occasion, all depending upon the person.

What to avoid that may cause fever blisters.

Though the root answer to what causes fever blisters is the above mentioned HSV, this virus will remain idle and harmless in the facial nerves until it is triggered. There are a number of triggers that should be avoided if you suffer from HSV, such as: exposure to direct sunlight, overly stressful situations, and trauma to the mouth region. Also, a variety of foods should be omitted from your diet or only eaten in moderation, like nuts, chocolate, and gelatin. Essentially, any foods which have a high acidity level should be avoided in order to prevent a fever blister outbreak. In addition to these common triggers, there are a handful which cannot be avoided. A cold or fever, are both examples of ailments that can bring about a bout of cold sores, as well as necessary dental procedures.

If you know beforehand that you may come in contact with any of these triggers you may want to ask your doctor to prescribe you medications that can prevent outbreaks of fever blisters. Also, avoid contact with others while you are experiencing one of these outbreaks, as the HS virus can be spread through contact with a fever blister. Another example of what causes fever blisters is eating from the same utensils as someone who currently has a cold sore or drinking from the same cup, as well as kissing or directly touching the blister. If you believe that you may have a fever blister then there are many treatments which can lessen the healing time and minimize the pain, even though there is currently no cure for the underlying cause.
