No matter if in the form of tiny blisters, large ulcerations or scabs, those painful and unsightly cold sores can be a source of sheer embarrassment. They usually heal in several days to 2 weeks. Sometimes people mistake cold sores for canker sores. There are two types of herpes simplex virus: HSV-1 and HSV-2. Both virus types can cause sores around the mouth (herpes labialis) and on the genitals (genital herpes).

The herpes simplex virus usually enters the body through a break in the skin around or inside the mouth. It is usually spread when a person touches a cold sore or touches infected fluid—such as from sharing eating utensils or razors, kissing an infected person, or touching that person’s saliva. A parent who has a cold sore often spreads the infection to his or her child in this way. Cold sores can also be spread to other areas of the body. The first symptoms of cold sores may include pain around your mouth and on your lips, a fever, a sore throat, or swollen glands in your neck or other parts of the body. Small children sometimes drool before cold sores appear. However, prescription oral antiviral medication may be helpful for shortening the episode if taken within the first 72 hours.

For some people, cold sores can be very painful. Your doctor can tell if you have cold sores by asking you questions to find out whether you have come into contact with the virus and by examining you. You probably won’t need any tests.

Avoid coming into contact with infected body fluids, such as kissing an infected person. Avoid sharing eating utensils, drinking cups, or other items that a person with a cold sore may have used. If you get cold sores often, treatment can reduce the number of cold sores you get and how severe they are. But there are some things you can do to reduce your number of outbreaks and prevent spreading the virus.

You may not develop cold sores when you are first infected with HSV. If cold sores do develop when you are first infected, they may be more severe than in later outbreaks. During the first outbreak of cold sores, the blisters may spread to any part of the mouth. Recurrent cold sores usually develop where facial skin and the lip meet. About 6 to 48 hours before a cold sore is visible, you may feel tingling, burning, itching, numbness, tenderness, or pain in the affected area. This is called the prodromal stage. People who have weakened immune systems are more likely than those with strong immune systems to have longer or more severe outbreaks of cold sores.

HSV infection may be life-threatening in certain people who have weak immune systems. One form of HSV infection is seen most often in children 1 to 3 years old. This type of HSV infection (primary herpes stomatitis) can cause a high fever and blisters throughout the mouth, which can interfere with the ability to eat. It can be serious in children—they can get quite sick from this illness, although they usually recover without any long-term problems. Your doctor can diagnose cold sores by asking questions to find out whether you’ve been exposed to the herpes simplex virus (HSV) and by examining you. No further testing is usually needed. There are two types of herpes simplex virus: HSV-1 and HSV-2.

Both virus types can cause lip and mouth sores (herpes labialis) and genital herpes if your skin comes into contact with either type. If it is not clear that you have cold sores, herpes tests may be done. The doctor takes a sample of fluid from a sore and has it tested. In essence you get one more cold sore and then are cured for life. If it is not clear that you have cold sores, herpes tests may be done.
