Use a special nasal rinse and slowly squeeze the rinse solution into the nasal cavity. When rinsing, you can adjust the rinsing pressure appropriately according to your own feelings to avoid damage to the middle ear caused by too high pressure.
If ear pain or other discomfort occurs during the rinse, stop using the nasal rinse and use a specialized nasal spray to administer the medication instead. Nasal sprays are divided into isotonic and hypertonic types, which can be selected according to medical advice.
