What are cold sores?

Cold sores are groups of fluid filled blisters, which may grow in size causing irritation and pain. The blisters associated with cold sores may weep and then crust or scab over. An outbreak usually starts with an annoying tingling sensation around the mouth, chin, nose or other areas of the face.

Cold sores are a common contagious infection. They are caused by a strain of the herpes simplex virus.

Symptoms – watch out for those tell tale signs!

Since we are all unique individuals, symptoms can be different for everyone:

  • You may experience no symptoms at all or you may have trivial symptoms such as a small spot which you don’t realise is a potential cold sore.
  • Some cold sore outbreaks will start with a tingling sensation around the mouth, chin, nose or other areas of the face before the blister appears.
