Cold sores and fever blisters are the same thing—both are caused by herpes simplex virus type 1 (HSV-1). So yes, they're a form of herpes, though this is different from genital herpes (usually HSV-2, though HSV-1 can also cause genital infection).

The key thing to know: having cold sores is extremely common—most people are exposed to HSV-1 in childhood, and many carry the virus without ever having symptoms. When sores do appear, they're usually triggered by stress, illness, sun exposure, or a weakened immune system.

Cold sores are manageable. Antiviral medications can reduce severity and healing time if started early. Over-the-counter treatments can ease discomfort. The virus stays dormant in nerve cells, so recurrences vary widely—some people have them frequently, others rarely or never again.

If you're experiencing active sores or have concerns about transmission or treatment options, a healthcare provider can offer personalized guidance and prescribe antivirals if helpful.
