If you don’t have a cold and one nostril is not working, it may be related to deviated septum, nasal swelling, inflammation of the nasal cavity and other reasons.
1. Deviated nasal septum: the nasal septum is bent to one side or has a localized bulge, which leads to the narrowing of one side of the nasal cavity and the symptom of nasal congestion.
2. Nasal swelling: such as nasal polyps, nasopharyngeal carcinoma, etc., can cause unilateral narrowing of the nasal cavity, and poor ventilation can occur.
3. Nasal inflammation: such as chronic hypertrophic rhinitis, unilateral sinusitis, etc., can lead to swelling of the nasal mucosa, causing unilateral narrowing of the nasal cavity, poor ventilation and other symptoms.
It is recommended that there is no cold and a nostril is not ventilated in time to go to the hospital, clear cause, under the guidance of the doctor for standardized treatment.
