Why do you have a cold sore if you are a preteen haven't kissed anyone and haven't shared drinks or utensils?

Answer 1

Cold sores are a form of herpes simplex. there are two types of herpes simplex, primary and secondary. Primary herpes is when you develop canker sores inside your mouth. Cold sores, also called fever blisters are secondary herpes and develop on the outside of the mouth and lips. As a child someone will usually pass herpes simplex (canker sores) to us innocently as a virus passed from adult to child. Later in life, flareups of the virus present as cold sores. Flareups can be triggered by stress, anxiety, cold, fever, injury to the mouth, dental work, food allergy, sunburn on your lips, etc. You can usually tell when a cold sore is developing because of the tingling in the skin in that area. If you start taking Vitamin C as soon as this tingling starts it will heal more quickly. Apply an over-the-counter product to assist in healing and wear lip balm with SPF protection to avoid further cold sores.
