Cold sores are small blisters that appear on or around your mouth, sometimes called 'oral herpes'.
Most cold sores heal on their own within 2 weeks and don't leave scars. However, they're very contagious - even when you can't see any blisters.
You can catch the virus through direct contact with someone who has a cold sore or their bodily fluids. This includes:
• kissing
• touching their skin
• sharing cups, cutlery, towels or toothbrushes.
There's no cure for cold sores, but treatments can help ease the symptoms. Talk to your pharmacist, doctor, or nurse about options that might work for you.
