Cold Sores

Cold sores, often known as fever blisters, are small, painful, fluid-filled blisters that develop on a raised, red area of the skin (usually the mouth and lips). This is an extremely common (and contagious) dermatological condition.

Cold sores are actually a reaction to the herpes simplex virus, and may not form for many days after exposure. The cold sores themselves usually last for seven to ten days; the blisters form, break, ooze, and then develop a yellow crust, which will eventually reveal pink skin underneath. Cold sores rarely leave a scar.

Cold sores usually clear up without medical treatment, but you should consult an Urgent Care LA doctor if:

  • You have a condition that suppresses your immune system
  • The cold sores do not heal within one to two weeks
  • Your symptoms are severe
  • You get cold sores frequently
  • You have eye irritation

At Urgent Care LA, our doctors will evaluate your dermatological problem to determine if you have a cold sore. Our doctors may prescribe topical treatments such as lidocaine or benzyl alcohol. For frequent cold sores, your doctor may suggestion an antiviral mediation.
