Cold sores, also called as fever blisters are small painful fluid-filled blisters that appear most frequently on the lips mouth or inside the nose. In rare circumstances like in case of immuno-compromised patients they may also occur inside the mouth. Cold sores are not same as canker sores.

What causes cold sores?
Cold sores are caused by herpes simplex virus (HSV). Two types of herpes simplex virus causes cold sores namely HSV-1 and HSV-2. Although in most cases HSV-1 is responsible for cold sore and HSV-2 is responsible for genital herpes, they may both cause cold sore on the lips or mouth.

Once herpes simplex attacks you there is no cure, it stays in your body throughout your life. But the good thing is that after primary infection herpes simplex stays inactive without causing any symptoms or any serious complications and you may live a normal healthy life. It may later reactivate to certain triggering factors like excessive stress or other factors that decrease your immune system. If you are struggling with recurrent herpes and looking for some cold sore home remedies, here we go:
