Z-Cold Sore

Cold sores or "fever blisters" cause a highly visible rash that appears on or near your lips. Recurrences are common and they are quickly and easily treated with an antiviral medication.

What causes a cold sore?

  • Herpesvirus-1 (HSV-1) infection is the most common cause, HSV-2 is less common
  • After an initial infection, cold sores will reappear occasionally
  • Stress or other illness may trigger a flare-up
  • Small blisters on or around the lips
  • Minor redness near the blisters
  • Clear liquid may drain from the blisters
  • Tingling may occur before the rash appears
  • There may be an enlarged lymph node in the neck or chin region
  • Recurrences may be in the same or different locations
