A cold sore is a virus infection near the lips
The symptoms of cold sores begin with local itching and burning of the skin near the lips. The skin swells and becomes red, after which small blisters arise. The blisters are later crusted and after a day or 10 the lip is usually cured again. People who suffer from cold sores regularly suffer from this. The virus infection is caused by the herpes simplex virus and is highly contagious. The virus sits in the blisters and (fresh) crusts, and by body contact the virus can be transferred. Causes of renewed infections include Disease (fever), decrease of resistance and combustion by the sun. Cold sores are difficult but generally not dangerous, for babies it is dangerous and sometimes fatal. Complications can occur if a second infection occurs, this can happen if the normal weather is disrupted, or if there is insufficient hygiene. Eye infections often occur when the hands and lenses have not been cleaned at the time of cold sores. There is medication available that can help prevent cold sores, so it is important to use these remedies when there is a tingling sensation in the lips.
