He didn't pay much attention to it then, but now there was a certain throbbing something on his lip and it wasn't pretty.
At first Neal thought it was a zit because it was red and tender, but then it blistered and opened up. Maybe you've heard of a fever blister — a cold sore is the same thing. So what exactly are cold sores and what causes them? Cold sores, which are small and somewhat painful blisters that usually show up on or around a person's lips, are caused by the herpes simplex virus-1 (HSV-1). They can sometimes be inside the mouth, on the face, or even inside or on the nose.
If they aren't taken care of properly, cold sores can develop into bacterial skin infections.
And they can actually be dangerous for people whose immune systems are weakened (such as infants and people who have cancer or HIV/AIDS) as well as those with eczema.
But not everyone who gets the herpes simplex virus develops cold sores. A person doesn't necessarily have to have a cold to get a cold sore — they can be brought on by other infections, fever, stress, sunlight, cold weather, hormone changes in menstruation or pregnancy, tooth extractions, and certain foods and drugs. Here's how a cold sore develops: The herpes simplex virus-1, which has been lying dormant in the body, reactivates or "wakes up."The virus travels toward the area where the cold sore decides to show up (like a person's lip) via the nerve endings.
The virus spreads through direct contact — through skin contact or contact with oral or genital secretions (like through kissing).
Although the virus is most contagious when a sore is present, it can still be passed on even if you can't see a sore.
The scab-like yellow crust falls off and leaves behind a pinkish area where it once was.
The redness fades away as the body heals and sends the herpes simplex virus back to "sleep."How Do Cold Sores Spread? If you have a cold sore, it's very easy to infect another person with HSV-1.
