Cold sores are actually brought on by a particular type of virus (the HSV-1, which is a version of the infamous herpes virus) that has the ability to make it quite painful to do things such as eat, drink, and sometimes even to sleep. There are quite a few other symptoms that can be caused as well and these can include sore throat, fever and sometimes even a swelling around ones neck area. Just the same as the more nasty type of herpes (which is caused by the HSV-2 virus), cold sores are extremely contagious and are very easily spread via types of physical contact. It is extremely important to try and avoid things such as kissing, partaking in oral sex, or even feeling the blisters.
What causes cold sores to suddenly appear? It can be several things, including fatigue, stress, injury to the lips, gums, or mouth, allergies, other types of infections, and even dental surgery or treatment. Doctors can easily diagnose cold sores, and often only a visual examination is necessary.
When it comes to preventing cold sores, there isn’t much you can do. If you come into contact with someone who has a cold sore, you may want to wash your hands frequently and try not to touch your face (especially your mouth, nose, and eyes).
Cold sores can be treated with an antiviral medicine prescribed by your doctor. This medication specifically works against the herpes virus, can help relieve many symptoms, and can make the cold sores vanish more quickly. You might also find an over-the-counter product that helps, but unlike a prescription medication, these products generally only combat the effects of a cold sore and don’t help get rid of it. Finally, cold sores usually vanish within about a week to ten days after they appear.
