Herpes in the Nose: Symptoms and Treatment

Herpes in the nose — nasal herpes — occurs when HSV-1 infects the nasal mucosa or skin around the nostrils. Nasal herpes is an uncommon but real presentation of HSV-1 infection, most commonly occurring from autoinoculation (touching an oral cold sore and then touching the nose), producing painful blisters inside or around the nostrils that are often mistaken for bacterial folliculitis or impetigo.

How Herpes Gets in the Nose

The primary route is autoinoculation: touching an active labial cold sore and then picking or touching the nose introduces HSV-1 to the nasal epithelium. The nasal vestibule — the skin-lined entrance to the nasal cavity just inside the nostril — is particularly susceptible because it's skin (not true mucosa) and frequently touched. Less commonly, herpes reaches the nose through respiratory droplets during close contact with someone in the shedding phase, or through HSV-1 reactivation along a nasal branch of the trigeminal nerve.

Symptoms

Nasal herpes produces: painful blisters or ulcers inside the nostril or on the skin at the nasal opening; burning, stinging, or itching at the nose before visible lesions appear (prodrome); crusting as lesions heal; and sometimes a blocked sensation or discharge if lesions are deeper inside the nose. The lesions are often misdiagnosed as bacterial folliculitis (infected hair follicles in the nose), nasal furunculosis, or impetigo. A cluster of painful vesicles that precede crusting is more consistent with herpes than the typical single tender nodule of bacterial folliculitis.

Treatment

Topical acyclovir 5% cream applied at prodrome onset. Oral valacyclovir 500mg twice daily for 5 days for more significant outbreaks or when topical application is difficult. For frequent recurrences: daily suppressive valacyclovir 500mg. Importantly: don't treat presumed nasal herpes with topical antibiotics — they won't work on a viral infection and delay appropriate treatment. If uncertain, a PCR swab from an active lesion confirms the diagnosis.

Prevention of Recurrence

The key preventive measure for nasal herpes is avoiding autoinoculation from oral cold sores: wash hands immediately after any contact with a cold sore; avoid touching the face, nose, or eyes when you have an active oral outbreak; don't share towels or face cloths during an active outbreak. Sunscreen on the lips and nose reduces UV-triggered reactivation of HSV-1.

Frequently Asked Questions

Can herpes in the nose spread to genitals?

Through the hands, theoretically. Touching nasal herpes and then touching the genitals could transmit virus, particularly during a primary infection before immunity develops. Wash hands during any active herpes outbreak at any body site.

Is herpes in the nose contagious?

Yes. Active nasal herpes lesions contain virus and are transmissible through direct contact. Avoid close facial contact with others during active outbreaks.

How do I know if it's herpes or a nose pimple?

Herpes: preceded by tingling/stinging, produces a cluster of small blisters, then ulcers, then crusts; recurs in the same location. Bacterial folliculitis/nose pimple: single tender nodule often with a visible pus point, not preceded by tingling, not clustered. A PCR swab of an active lesion is definitive.
