A fever blister is a common disorder of the mouth and is also known as a cold sore. A fever blister causes much uneasiness and irritation in people who experience them. These cold sores usually take place outside the mouth especially on the lips, the chin, and the cheeks and sometimes inside the nostrils.


Fever blisters do occur inside the mouth, and when they do so, it is usually seen on the roof of the mouth and on the gums. If fever blisters take place inside the mouth, they usually heal much more rapidly than fever blisters outside the mouth. One of the main reasons for a fever blister cause is due to a contagious virus known as herpes simplex.


The herpes simplex virus is extremely contagious especially when the fever blisters are in its early stage. The virus is usually spread by kissing, and children are often victims of this virus attack by being in contact with their parents, their siblings and close relatives who are suffering from fever blisters.

Fever blister symptoms are often disconcerting and individuals always almost experience in recurrent attacks of fever blisters. People who have recurring fever blisters experience extreme itchiness, tingling and burning around the area before the fever blisters make an appearance. There are several factors that trigger an outbreak of herpes simplex in the form of fever blisters. Emotional strain and stress, high fever, prevalent illness, and chronic exposure towards sunlight are some of the many factors that weaken the body's defenses thus triggering an outbreak of fever blisters. At present, there is no final cure or solution for fever blisters. Most medications that are used in the treatment of fever blisters help in relieving the pain and discomfort linked to the cold sores. Various topical applications and medicated ointments help in numbing the fever blisters while antibiotic medications help in controlling secondary infections while specific ointments help in softening the outer covering of the cold sores. Most medical researchers who are currently working on various kinds of medications are trying to develop a promising vaccine for the herpes simplex virus. Although research seems to be encouraging, medical scientists believe that they require many hours of studies for the safety and efficacy of the vaccine before announcing it to the world. However these experts believe that the herpes Simplex vaccine would be useful only for those individuals who have not been affected with the herpes Simplex virus.
