What are Fever Cold Sores? A lot of people have fever cold sores, but really don’t understand it. A cold sore is essentially a blister that will grow around your lips. The term fever gets associated with this because your body will end up getting a fever the first time that you experience this. A lot of people assume that these blisters are some sort of irritation or just an infection, but it’s actually caused by a virus. 8 out of 10 people have the HSV-1 virus in their body right now. There is no way to cure it and it is what leads to the sores on your lips. So now you know what fever cold sores are. Your body and medical science still have a lot of obstacles to overcome when it comes to nerves in the human body. The way antibiotics and antibodies work is that they’ll destroy any cells that a virus infects. The problem is that the HSV-1 virus will hide in your nerve cells. You can’t destroy nerve cells or you’re going to get into big trouble. Things will stop working. That’s how this virus can hide in your body for years without having an outbreak, and just one day you’ll end up with cold sores. The reason that you’ll have an outbreak of fever cold sores is that your immune system is weak. This could be due to just having a cold or maybe you’re stressed out from work. Anything that can leave to your immune system being weak will probably lead to an outbreak of cold sores. Learn how to Cure Cold Sores Fast
