What are Cold Sore Symptoms?

7 symptoms you may experience

Some people who carry the herpes simplex virus type 1 (HSV-1) virus experience no cold sore symptoms at all. For those who do, mild-to-severe symptoms appear around the lips or mouth area.

Cold sore symptoms you may experience

  • Pain
  • Itching
  • Dryness
  • Cracking
  • Redness
  • Scabbing
  • Irritation

Before a cold sore blister appears, some people even experience a sore throat, fever, swollen glands or painful swallowing.

Most cold sore symptoms go away in 7–12 days, but there are ways to reduce future outbreaks, like avoiding triggers.
