The right nostril seems to be swollen at the innermost part of the nostril may be related to trauma, rhinitis, boils and other causes. 1. Trauma: If the right nose is hit by an external force, the soft tissues inside the nasal cavity may be injured, and swelling and pain may appear inside the nostril. 2. Rhinitis: If you suffer from rhinitis, the mucous membrane of the nasal cavity can become swollen under the stimulating effect of inflammation. 3. Boils: As a result of frequent digging of the right nose during the day, the inside of the nostril may become infected and boils may form, causing swelling inside the nostril. It is recommended that the person whose right nostril seems to be swollen should go to a regular hospital in time to clarify the cause of the disease and carry out standardized treatment under the guidance of the doctor, so as to avoid delaying the condition.
