How to Get Rid of a Cold Sore Overnight


Have a tingling feeling in your lip? A new bunch of blisters may be set to erupt.

Cold sores, also known as fever blisters, are painful outbreaks that usually appear around the lips, nose and chin.

The condition is caused by herpes simplex virus type 1 (HSV-1) and is highly contagious, especially if the blisters are oozing fluid. However, the virus does not always cause sores and may sometimes stay dormant permanently. The virus spreads through skin-to-skin contact, and oral sex can spread genital herpes to the mouth area.

Factors like hormonal changes in the body (especially during menstruation), fever, fatigue, emotional stress, skin trauma and excess sun exposure may also reactivate the virus, thus contributing to an outbreak of sores.

Cold sores usually go away on their own within a week or so. They may burst, ooze out fluid and crust over in a span of time. However, they may be extremely annoying and terrifying to look at. And there is definitely no one-day cure to get rid of them.
