The cold sores are caused by the herpes simplex virus. The first cold sore usually occurs in the childhood. It affects the inner skin that lines the mouth, and it can be passed on by skin contact. The first infection usually does not cause any symptoms.
First cold sores appear in childhood
After the first infection, the virus remains in the body for the rest of the life. In the majority of the cases it is inactive, but once in a while it can become active. When it is active, the virus multiplies and causes blisters around the mouth.
The reason why the virus becomes active is unknown, but there are certain theories about these causes. Many cold sores occur when one suffers of flu, colds, and other illnesses. It is also common for cold sores to appear during the monthly periods. Stress can also lead to the development of cold sores.
Cold sores have various symptoms which are easy to recognize. An itch or a tingle might develop around the lips or nose prior to the appearance of the blisters. After the itch, the sores usually appear.
The cold sores can be very painful, and it might take days for them to go away. The cold sores are infectious, and they can be spread to other people.
You will have to wait until the sores are completely dry and have scabbed over. In the majority of the cases, the scabs will go away in a week or so, the pain becoming less intense.
You should remember not to pick or touch cold sores. When you apply creams or gels, try not to rub them in the sore. In case you rub them in, the sores might break and that will cause pain.
When you apply cream or gel, you should do it with clean hands. You can ease the pain with ibuprofen, paracetamol, and certain creams.
You should never share lip balms if you have cold sores, because the other person will get them from you.
Take care of cold sores in the proper manner
There are various treatments for cold sores. You could use antiviral creams such as Penciclovir and Aciclovir, which can be bought over the counter.
These creams will not kill the virus, but will prevent it from spreading. These two creams need to be applied very often, otherwise they are not effective.
You could also take antiviral tablets in order to take care of the cold sores. Aciclovir can also be bought in tablet form. They have the same purpose as the creams and gels, as they do not cure the cold sores or prevent their development, but they only stop them from multiplying.
People with immunity problems, newborn babies, and people who have very aggressive cold sores will need to take the tablets. You should go to your doctor only if the cold sores are still preset after more than ten days.
