When to See a Doctor
Most cold sores heal on their own, but you should see a doctor if:
-
Sores last longer than 10–14 days
-
Outbreaks are frequent or severe
-
The infection spreads to your eyes or other areas
-
You have eczema or a weakened immune system
Doctors may recommend episodic therapy (taking antivirals when symptoms start) or suppressive therapy (daily medication to prevent outbreaks).
