A burning nose is a burning sensation in the nose, which may be related to nasal vestibulitis, dry rhinitis, boils and other causes. 1. Nasal vestibulitis: Nasal vestibulitis is caused by repeated stimulation of the nasal vestibular skin by nasal secretions, which may result in localized skin pain, redness, swelling, itching and other symptoms. 2. Dry rhinitis: Chronic rhinitis caused by stimulation of external environmental factors, which can be manifested as dryness of the nasal mucosa, causing itching with mild burning sensation inside the nose. 3. Boils: Staphylococcus aureus and other pathogenic bacteria invade individual hair follicles, which can lead to suppurative lesions in the hair follicles, manifesting as local redness, swelling, heat and pain. It is recommended to go to the hospital in a timely manner to clarify the cause of the disease and standardize the treatment under the guidance of the doctor.
