What Causes Cold Sores
An Account On What Causes Cold Sores
What causes cold sores is a common question asked by anyone suffering from acute cold sores. Cold sores, often called “fever blisters”, are lesions or fluid-filled blisters that appear on the soft puffy areas of the skin like lips or the area near the mouth. Suffering from these lesions can be really painful at times. They also give rise to burning sensation and skin irritation. They last for a couple of weeks. They cannot be fully cured with medication but they don’t cause any harm in the body even if they are left untreated.
Cold sore is a kind of viral infection but the body’s defense mechanism is unable to completely eliminate the cold sore viruses from the body. As a result, there are chances that they will recur at some point of time. In answer to what causes cold sores, it has been found that cold sores are actually caused by the herpes simplex virus 1 or HSV-1. There are two kinds of herpes simplex virus, HSV-1 which is responsible for causing oral herpes or cold sores and HSV-2 which causes genital herpes. However, HSV-1 is more common. It is interesting to know that cold sores do not occur due to the sudden invasion of the herpes simplex virus 1. These viruses or germs already reside dormant in the human body from a very early age and it is only when they get reactivated that they cause the outbreak of cold sore blisters. It is not possible to detect or diagnose cold sores at an early stage because it is not caused by the initial contact with the HSV-1.
The early symptoms of this disorder are having headaches, having difficulty in swallowing food and running fever. A couple of days after the occurrence of these symptoms there will be pain in the mouth and the gums will start swelling. After that, blisters will appear near the lips or mouth and these blisters will gradually grow with fluid inside them. The pain and discomfort will persist until the cold sores get completely healed. This was a short account on what causes cold sores.
