A deviated nasal septum may not need surgery unless it is causing severe blockage, frequent sinus issues, or breathing difficulty. Try steam inhalation, avoid dust and cold air, keep your nose moist, and manage symptoms with a simple routine to get relief. Sleep with your head slightly raised and stay well hydrated to reduce discomfort. If symptoms persist or affect daily life, consult a doctor to determine whether surgery is needed or can be managed without it.

Blocked breathing through one nostril is often due to a deviated nasal septum, swelling from a cold or allergy, or a nasal blockage such as a polyp. Since salt water has not helped, try steam inhalation, keep your nose moist, avoid dust and smoke, and stay well hydrated to reduce swelling. You can also use a saline spray regularly and sleep with your head slightly elevated for better airflow. If the problem continues or worsens, consult a doctor to determine the exact cause and receive appropriate treatment.
