Cold sores resemble small blisters on the lip or around the mouth. Many people carry the virus that causes cold sores. The virus always remains in the body, even after the physical symptoms disappear and can reactivate at any time. The sores tend to heal within 3 weeks. However, there is no easy way to predict how often someone will contract a cold sore. This can be once per year or every month. Cold sore outbreaks can be triggered by stress, menstruation, sunlight, sunburn, fever, dehydration, or local skin trauma
Cold sores are caused by a virus called herpes labialis. An infection occurs when the herpes simplex virus comes into contact with tissue of the mouth or with abraded skin around the mouth.
To provide advice on how to manage cold sores, dermatologist Professor Bruce A. Brod from the University of Pennsylvania, Perelman School of Medicine, has provided Digital Journal readers with some useful information.
Outlining what cold sores mean, Professor Brod says: “Cold sores are different from canker sores, which are not caused by a virus and occur inside of your mouth.”
He also notes that “Although most cold sores heal on their own, there are many things you can do to help manage your symptoms. To treat cold sores at home.” For this reason, the professor has provided the following advice:
Slow the outbreak
Burning, itching or tingling may be the first sign that a cold sore is coming. When cold sores appear, apply an over-the-counter antiviral cream or ointment. Although this isn’t always effective, doing this may help slow the reproduction of the virus and relieve symptoms.
Another important thing is to stop the cold sore from spreading. When you have a cold sore, Professor Brod says that it is best to avoid intimate contact, like kissing. Also, sharing things like cups, towels, razors, and toothbrushes should be avoided.
Reduce pain
Consider taking ibuprofen or acetaminophen to help reduce pain. Brod adds that prescription oral antiviral medication can sometimes be helpful in shortening an episode; however, these need to be taken within the first 72 hours of the cold sore appearing.
Avoid foods that contain acid
While you have a cold sore, avoid foods that contain acid, such as tomatoes and citrus fruits. These could irritate the skin and add to any pain.
Cool the sores
Place a cool, wet towel on the cold sores for about five to 10 minutes. Do this a few times daily to help reduce the redness and irritation.
