Cold sores are usually confined to the mouth area (particularly on and around the lip). Less commonly, cold sores can occur on other facial areas such as above the mouth, the nose, nostrils, cheek or chin. Cold sores can also appear on the fingers, this is referred to as 'Herpes Whitlow'. Cold sores do not usually occur inside the mouth, however if they do, it is most likely on the gums or hard palette (roof of the mouth). If the lesion appears inside the mouth, especially on the soft tissue, it is most likely to be a canker sore, not a cold sore. More information about what Canker Sores look like. When cold sores reoccur they will typically appear in the same location that they did during previous outbreaks.

Following the primary infection, the herpes virus becomes latent (it goes to sleep) deep inside nerve cells. Scientists are not yet sure why some people have many cold sore recurrences per year and yet others seem to be protected and may not get lesions as often or at all. Recurrent infections can be triggered by many different stimuli. The most common "cold sore alarm clocks" are fever (ergo "fever blister"), and exposure to the sunlight (UV-B). Other stimuli include localized trauma to the mouth (such as dental work and cosmetic procedures to the face), other illness, and emotional stress. For some individuals, recurrences are unpredictable and have no recognizable cause. In fact, some literature suggests that the viral DNA may trigger itself. Others are very aware of what kinds of events will likely lead to recurrences and can anticipate the need to begin treatment as early as possible in an acute episode.
How To Prevent Cold Sore Outbreaks
Cold sore is a painful nuisance that you should avoid. It is caused by herpes simplex virus that commonly appears around the mouth, nose, and chin as painful blisters.

Nutritious diet and vitamins. You are prone to cold sores when your body defenses or immune system weakens and nutritious foods can help improve your immune system to prevent cold sore outbreaks. A diet high in lysine and low in arginine helps prevent cold sore outbreaks. Lysine slows down viral reproduction and arginine aids the growth and reproduction of herpes simplex virus. You can boost your lysine intake by eating milk, potatoes, beans, chicken and fish. Doctors may also recommend supplements if you need higher amount of lysine. Avoid foods high in arginine such as chocolates and nuts. Add more vitamin C to your diet, this will help boost your immune system and prevent cold sore outbreaks. Avoid triggers. Stress, not enough sleep, staying in the sun for a long period of time, cold and flu are some of the triggers of cold sores that can be avoided.
