Burning Smell in Nose: Causes & Relief

A burning sensation or phantom burnt smell (phantosmia) in the nose can stem from several causes:

• Sinusitis – inflammation alters olfactory perception; may cause burning.
• Allergic rhinitis – mucosal irritation, congestion, altered smell.
• Nasal polyps – obstruct airflow, cause inflammation, reduce smell.
• COVID-19 – anosmia/parosmia/phantosmia common; may include burning.
• Neurologic – seizure, migraine, Parkinson's, tumor (rare).
• Medications – certain drugs alter smell/taste.
• Environmental – smoke, chemicals, dry air.

When to see a doctor: Persistent (>2 weeks), worsening, accompanied by headache, vision changes, nasal bleeding, or systemic symptoms. Evaluation includes nasal endoscopy, imaging, olfaction testing.
