Cold sores, also called fever blisters, appear as small blisters on the lips and around the mouth. The skin around the blisters turns red and swollen. If the blisters break open, a clear fluid oozes out.Cold sores are a viral infection caused by the herpes simplex virus (HSV). Both HSV-1 and HSV-2, the two kinds of this herpes simplex virus cause mouth sores. This virus is also found to be the cause of genital herpes.
This infectious virus generally enters the body through some break that occur in the skin around or inside the mouth. It spreads from one person to another when the sore or the fluid inside is touched upon. Sharing utensils and razors might also transfer the infectious germs. Needless to say, kissing and other means through which saliva contact occurs such as oral sex result in direct transmission of infection.
The initial symptoms of cold sores include pain around the mouth and lips. In some people, fever, sore throat, or swollen neck glands also appears as a result of cold sores. Kids usually drool before being attacked by cold sore germs. Once the blisters are broken, the sores will disappear within two weeks. However, in some people, although the infectious virus makes its way into the body, no cold sores will develop.
If you experience severe pain, it is better to consult a doctor. Usually, no tests are done as part of diagnosis. Skin creams, ointments and sometimes pills are prescribed as medication. It is found that with effective treatment one can get cured of cold snore a couple of days faster. However, it should be remembered that herpes simplex virus, that caused the infection will not be eliminated from your body. Once infected, cold snores will remain in your body for the rest of your life. Treatments help in reducing the number of cold snores that you are likely to develop.
