The cold sores are the disease that will generally affect mouth and the nose. The cold sores are a viral infection and it causes small sores on the mouth nose and other parts of the body. The herpes simplex type 1 is responsible for the infection of the mouth and nose.
It infects the lower part of the nose or sometimes the infection also reaches in the nose. In the nose it affects generally the nostrils. In these disease sores are developed on the skin bellow nose and also inside the nose. These sores are small in size however they grow in the form of groups and therefore they can be painful. The skin where the infection occurs becomes red and appears as inflated. After some time of occurrence of the infection the sores grow in size and finally they burst i.e. they break open and dispose out a clear fluid. This may happen because of mechanical stress as touching with the finger etc. When this happens a curst is developed in the area of the infection.
However after this, the sores disappear themselves without doing anything. Therefore they may disappear even without the need to take medication.
As the sores appear in groups containing a large number of sores, the nose becomes very painful. They also cause itching. If they appear bellow the nose they are visible externally and therefore they cause embarrassment for the patient.
The infection occurs when the patient comes in to contact with the germs i.e. the herpes. They spread from the infected person to the other people. This happens when they sneeze or through the common use of things like towels, napkins, etc. it also occurs because of the touching the sores with the hand or other body parts.
Once the virus herpes simplex enters the body of the patient it may remain inactive for sometime. However due to some stimulus as cold or some other chemical stimulus also it may give rise to the sores on the skin. Therefore they occur commonly during the cold season and so called cold sores.
They can occur to people of any age from children to adults. However, in some 20 to 40% people though the herpes enters their body it remains inactive. It is not able to grow and create the symptoms of cold sores in them.
The remaining ones show the symptoms of the infection externally.
The complete cure from the infection is not possible. The virus remains in the body for ever though it may become inactive for sometime because of the cure methods. Therefore the cold sores occur frequently throughout the life of the patients.
The sore disappear naturally after their occurrence. This takes a time of about two weeks. Many types of creams and antiviral medicines are available in the market. However these will only reduce the time of healing by about 3 to 4 days. However they give immediate from the pain that these sores cause.
Using the natural substances as the lysine, zinc vitamin c etc can help in reducing their occurrence. In addition to this it has been found that the amino acid Arginine is rerqired by the virus for their growth and therefore the patients should avoid eating foods containing Arginine.
Also it is important that though the sores may cause itching they should never be scratched or they will spread to the nearby region
