Health Tip: What Causes a Cold Sore?

(HealthDay News) -- A cold sore is a painful sore that often forms on the lips or around the mouth. While a cold sore is caused by the herpes virus, many factors can act as triggers.

  • Feeling run down, stressed or tired.
  • Having the flu, a fever or a cold.
  • Being exposed to the sun.
  • Having hormonal changes as a result of pregnancy or menstruation.
  • Having an injury or trauma to the face from a cut, dental work, shaving or surgery.
