Nobody likes cold sores – they are rather unsightly. They are usually caused by a virus that is spread by direct contact – kissing someone who has a cold sore usually. If you can avoid this kind of activity you are much less likely to catch them.

Other things that can make cold sores appear are:
• being run down,
• illness
• stress
• strong sunlight
• very cold winds
• or a menstrual cycle

If you do suffer from cold sores you will often experience a tingly sensation on your lip just before the cold sore appears. If you apply an anti-viral cream such as Zovirax at this time you can sometimes stop them appearing.
