Whistling in your nose
If you’d rather not whistle while you work (or breathe), a squeaky nose can be a major annoyance. It is typically a sign of airflow obstruction, which may mean excess mucus is covering the nasal passages. A decongestant (for a cold) or an antihistamine (for allergies) can help clear out the gunk. See a doctor if you experience whistling after nasal trauma. It could be a tear in the cartilage between the nostrils, which is usually repairable.
