But there are things you can do to help ease the pain. Cold sores should start to heal within 10 days, but are contagious and may be irritating or painful while they heal.
Some people find that certain things trigger a cold sore, such as another illness, sunshine or menstrual periods. Cold sores are contagious from the moment you first feel tingling or other signs of a cold sore coming on to when the cold sore has completely healed. You can buy electronic devices from pharmacies that treat cold sores with light or lasers. Some people find these helpful, but there have not been many studies to confirm if they work. If you regularly get cold sores, use antiviral creams as soon as you recognise the early tingling feeling.
They do not always work after blisters appear. Cold sores take time to heal and they're very contagious, especially when the blisters burst. By clicking the link s above, you will be taken to an external website that is independently operated and not managed by GSK.

You'll feel a tingling, itching, or burning sensation on your lip, mouth, or nose where a cold sore is imminent. It creates a barrier to protect healthy skin cells, blocking the spread of HSV For instant relief, put ice in a bag and wrap in a thin cloth before placing it on the area for no longer than 20 minutes.
Ice slows blood flow to the affected skin, reducing the inflammation, swelling, and nerve activity that leads to discomfort. Within 48 hours, a cold sore blister may appear around your mouth or lips, though you can get them anywhere on your face, including around your nose. A cold sore results in a swollen lip as the blister develops. The blister may look like a group of small, fluid-filled bumps surrounded by red, swollen skin. The bumps may grow and multiply and can be painful, too. You can soothe pain and discomfort with over-the-counter painkiller medication such as ibuprofen or acetaminophen.
Alternatively, local anesthetic creams such as lidocaine or benzocaine temporarily block nerve signals in your skin, numbing pain and stopping itching. Never squeeze the blisters as this can help spread the virus and even lead to scarring.
This stage can be the most painful cold sore stage, as the blisters burst, leaving open sores. Stage 3 is the most infectious stage, so take care to avoid spreading the virus until your cold sore has completely healed and disappeared.
The HSV-1 virus is highly contagious. It spreads through skin-to-skin contact or via the moist inner skin that lines the mouth, eyes or genitals. It can also be sight-threatening if it reaches your inner cornea, the transparent layer at the front of your eye, and is left untreated.
Avoid touching your cold sore and always wash your hands after applying cream or before touching your eyes, genitals, or areas of broken skin.
