Description
Cold sores and fever blisters are caused by herpes simplex virus type 1 (HSV-1). This virus is passed from person to person by saliva or by skin contact. Cold sores usually appear as clusters of tiny blisters on the lip. About 8 out of 10 people have the virus that causes cold sores. Most people are first infected before they are 10 years old. After this first infection, the virus remains dormant (inactive) in the nerves of the face. It can become active again and cause cold sores because of stress, illness, trauma, dental treatment, or sun exposure. HSV-1 can cause serious illness in people with weak immune systems or those who have health problems.
Symptoms
Fever, headache, nausea, vomiting, painful swelling, and open sores are common during the first infection. When the virus is activated again, tingling, burning, itching, swelling, or redness may occur. Within a day or two, painful sores appear.

Treatment
Treatment may involve pills or creams that help cold sores heal faster as well as relieve pain. These medicines should be used when early symptoms start, before a cold sore appears. Some people who are prone to cold sores take the medicines when they are under stress to prevent outbreaks. During an outbreak, it's important to keep the area clean, don't touch it and use lip balm. Avoid kissing and sharing utensils and other items that touch the mouth. Cold sores usually heal in two to four weeks.
