Cold sores which are also often
known as fever blisters, are those
small sores which appear on and above the upper lip,
the corners of the mouth as well as on the face. Cold
sores are very common and can be easily spread.
There are about 100 million recurring infections annually in the United States alone. Many people wrongly believe that cold sores are as a result of a head cold. They are a viral infection caused by the herpes simplex one virus. The virus tends to remain dormant in the nerve cells and it is there for life. There are certain elements that may trigger cold sores and these include:
- Overexposure to the sun
- Illness and injury
- Fever
- Weakened immune system
- Emotional stress and fatigue
- Hormonal changes among pregnant women and women
in their menstrual cycle
There is no cure for cold sores but they do eventually
go away.
There are several stages in the life of a cold sore.
When a cold sore is about to appear, there will be
a tingling sensation in that area and then redness.
Then the cold sore will start to form as very small
blisters or these may group together and appear bigger.
The third stage is the cold sore becoming a red sore
which is most noticeable even by those who have never
had a cold sore. These become painful blisters and
are very contagious.

Towards the end, the cold sore starts to heal when a brown scab may form over the area. However, if this scab cracks open it may bleed. In the final stages of healing, the cold sore goes from brown to yellow. The whole cycle takes about ten days.
Cold sores do occasionally occur inside the mouth
and then normally on the gums or the roof of the mouth.
These cold sores in the mouth are quite small and
often begin as a blister. They can heal quite quickly.
The first sign is often a tingling and itchiness around
the tongue, gums or the inside of the cheeks. A soft,
bland diet is recommended to avoid irritating the
sores and surrounding sensitive areas of the mouth.
