A cold sore usually starts with a tingling, itching or burning feeling, they are common and usually clear up on their own within 10 days. They’re contagious until they go away.
How can I avoid triggers? Suggested lifestyle changes…
Some people find that certain things trigger a cold sore, such as another illness, sunshine or periods. If you regularly get cold sores, it may be a good idea to keep antiviral cream in your medicine cabinet. As soon as you recognise the early tingling feeling of a cold sore use the antiviral creams as they don’t always work after blisters appear.
Why do Cold Sores come back?
Cold sores are caused by a virus called herpes simplex. Once you have the virus, it stays in your skin for the rest of your life. Sometimes it causes a cold sore. Most people are exposed to the virus when they’re young after close contact with someone who has a cold sore. It doesn’t usually cause any symptoms until you’re older.
How do I treat?
Cold sores take time to heal and they are very contagious, especially when the blisters burst. Don’t kiss babies if you have a cold sore. It can lead to neonatal herpes, which is very dangerous to newborn babies.
