Bloody nose and fever: what to know

Fever is a symptom rather than a diagnosis. Respiratory infections such as Common Cold, COVID-19, Acute Bronchitis or Bronchiolitis can inflame the nose and make its small surface blood vessels easier to disturb. Repeated rubbing, forceful blowing, dry air and dehydration can add irritation. Some childhood illnesses, including Chickenpox or Croup, may also bring fever with nasal symptoms. Brucellosis and Cellulitis are less typical possibilities that require clinical assessment when other symptoms point that way.

The fever does not explain every nosebleed. A nosebleed can start from one nostril after sneezing, blowing or picking, while the fever comes from a separate infection. Tell a clinician about the temperature, other symptoms, medicines, recent nose injury and whether bleeding is recurring.

Sit upright and lean slightly forward so blood leaves the mouth rather than running down the throat. Pinch the soft part of the nose continuously for ten minutes while breathing through the mouth. Do not tilt the head back, pick the clot or blow the nose immediately afterwards. Sip fluids if you can, rest, and use a humidifier or saline spray for dryness. Follow label directions for fever medicine and check with a pharmacist if you have another illness or take regular medicines.

Seek urgent help if bleeding is heavy, follows a significant injury, causes faintness or breathing difficulty, or does not stop after firm pressure. Get prompt medical advice for fever with a stiff neck, confusion, a widespread rash, severe weakness, repeated vomiting, unusual bruising or bleeding elsewhere. Children, older adults and people with reduced immunity may need earlier review. Arrange an appointment when fever continues, nosebleeds keep returning, or symptoms are worsening.

Ask whether the pattern fits an infection, nasal dryness or another cause; whether your medicines can increase bleeding; what temperature or symptoms should trigger review; and how to prevent further irritation while you recover.
