Cold Sore Sufferers Have Cause To Celebrate

They need never have another cold sore again

Cold sores are a group of tiny blisters that can occur anywhere, but most commonly occur on the lips, around the mouth, and around the nose. After a few days, the blisters change into a sore with an overlying crust/scab.

Cold sores can be very painful, unsightly, and can be transmitted to others. Cold sores are also called “fever blisters” because it is a viral infection that can be activated by illness (fevers or colds).

Why should I care about cold sores?

Cold sores are a recurrent viral infection that cannot be cured. Cold sores are caused by infection with the herpes simplex virus. It can become reactivated during periods of stress, extreme sunlight exposure, or illness (fevers or colds). It is very common, and some estimates say that 100 million people are infected or have been exposed in the United States alone. Unfortunately, once you have the infection, the virus still remains inactive in nerve cells and is triggered to recur again during periods of stress, intense sunlight exposure, and illness.

What causes cold sores?

Cold sores are caused by infection with the herpes simplex virus. It can be transmitted by kissing, sharing eating utensils, or touching the area on other infected persons. They most commonly affect the lips, mouth, nose, chin or cheeks.

The infection usually lasts seven to 10 days. Some make a distinction between herpes simplex 1 and herpes simplex 2. Both types can occur on all areas of the body. This discussion will be limited to cold sores around the mouth.

 

What are symptoms commonly associated with cold sores?

There are usually three stages that occur as cold sores develop:

• Tingling, burning and itching. This can occur a few days before the actual blisters appear in the area.

•  Small vesicles, usually grouped together, are the first visual sign of a cold sore.

•  Oozing and crusting. The tiny blisters may join and break open. This can leave a small area of bare skin that may ooze and then crust/scab over.

 

How are cold sores diagnosed?

Characteristically there is a burning, itching or tingling that precedes the development of the blisters by one or two days. With the medical history of preceding burning, and the classic presentation of a group of tiny blisters on a red base (near the lips, mouth or nose), the diagnosis is easily made by a physician.

 

Can cold sores be prevented? 

Yes, by preventing the transmission of the viral infection. This can be done by not engaging in kissing, sharing eating utensils, or touching someone else during an active infection. Also, by taking oral prescription medications at the first stage of burning, oftentimes the blisters or blistering stage can be prevented from occurring.

 

How are cold sores treated?

There are many over-the-counter cold sore treatments, but in my experience their effectiveness is poor at best. I prefer to use prescription and oral medications such as Acyclovir, Famciclovir or Valtrex. As mentioned earlier, if used appropriately, especially at the time of the itching or burning, they can prevent the development of cold sores.

 

Action steps for anyone with unwanted cold sores

Talk to your doctor about prescription medications that can be taken when you first notice the itching and burning or tingling. It’s very important to have the medicine readily available. The ability for the medication to prevent the cold sore from occurring is based on how quickly you take it after you experience the burning or tingling “warning sign.”

There are different treatment plans based on how frequently you get cold sores. Your doctor will recommend that best treatment option for you.

I tell my patients to keep the medicine very handy, such as in their purse or automobile glove compartment, desk drawer or locker at work, etc. Most patients with recurrent cold sores don’t know that there is a great treatment to prevent the development of cold sores. I tell my patients, “You should never have another cold sore again!”
