Cold Sore

Medically termed as Herpes labialis, Cold Sore is referred to as the infection of the lips, gums or mouth caused by the herpes simplex virus type 1, forming small yet painful blisters (also known as fever blisters). People may get affected by cold sore even at the age of 20. Initially, it may not cause any symptoms or mouth ulcers, while the virus remains inactive within the face’s nerve tissue. However, some people experience the reactivation of virus, releasing recurrent cold sores in the same area, but are not severe. Cold sore is diagnosed on the basis of the nature or appearance of the lesion.
