Cold sores are painfully annoying to deal with and not a pretty sight, either. Because they appear around the mouth or on the lips, they are hard to hide with makeup. Surprisingly, there is some confusion as to what a cold sore really is. Learn the truth behind what a real cold sore is so you’ll know how to treat it properly if you happen to get one.

Cold sores, also called “fever blisters”, are small blisters that are red in appearance and tender. Cold sores are caused by herpes simplex virus type 1, so if someone tells you that you have herpes around your mouth, don’t faint - they’re telling the truth. Obviously this is a different type of herpes that should not be confused with the STD (this form of herpes is caused by herpes simplex virus type 2). The two are not the same. While it is possible for herpes simplex virus type 2 to cause cold sores and vice-versa, these instances are rare. However, the virus responsible for creating cold sores does make them highly contagious.

Another common mistake made when it comes to cold sores is confusing them with canker sores. For one thing, canker sores are not contagious and only occur inside of the mouth, not on the outside like cold sores. Canker sores are actually ulcers that occur in the soft tissues inside of the mouth.

Cold sores are characterized as small, red blisters filled with fluid. These blisters often appear on the lip itself or around the lip area. A tingling sensation and increased sensitivity of the area are also common. Unfortunately, cold sores cannot be cured, only treated. Because it is highly contagious, you should avoid close contact with anyone who has a cold sore. The most common ways to contract a cold sore is by skin-to-skin contact, sharing eating utensils, kissing, or sharing other personal facial hygiene tools (razors, towels) with someone who has an open lesion.

If what you have in indeed a cold sore, the most important thing to do is stay away from anyone who may have a weak immune system or one that isn’t very strong to begin with, such as infants. Avoid close contact with people suffering from health conditions such as cancer, AIDS or skin conditions like eczema. These particular individuals are at greater risk of developing infections if they contract your cold sores.

A cold sore usually goes away on its own but if you don’t have that kind of patience, you can purchase over-the-counter creams to relieve any pain or discomfort or take a pain reliever. Applying a warm or cold compress to the cold sore can also take away any pain and be sure to avoid picking, scratching or squeezing your cold sore. That will only make it worse. If your skin starts to get dry or crack, apply Vaseline or other lip treatment to keep the area well moisturized.
