What is a red nose?

Common Cold (Rhinitis)

A red, sore, or runny nose is a frequent sign of a common cold, which is caused by a virus.

Allergies

An allergic reaction happens when your immune system overreacts to a foreign substance, such as pollen or pet dander. Sneezing, a runny nose, and nasal congestion are all symptoms of allergies.

Sinusitis

Sinusitis is inflammation of the sinuses. This can cause a red nose in addition to facial congestion and pressure, and a thick nasal discharge.

Trauma (Skin Injury)

A skin injury, such as a cut or scrape, on your nose can cause it to become red and swollen.

Rosacea

Rosacea is a chronic inflammatory skin condition that can cause redness, pimples, and thickening of the nose skin.

Drug Side Effect

Certain medications such as some birth control pills, blood thinners, alcohol, and cocaine can cause a red nose.

Skin Infection (Cellulitis)

A skin infection caused by bacteria might result in redness and swelling of the skin around the nose.

Hay Fever (Allergic Rhinitis)

Hay fever, also known as allergic rhinitis, occurs when the nose and throat become inflamed in response to pollen or other environmental triggers. Common symptoms of hay fever include a red, runny nose, itchy eyes, and sneezing.
