IF YOU FEEL SALINE GETTING INTO YOUR EARS, STOP DOING THE FLUSH. Some people, due to anatomical differences, can possibly get saline into their Eustachian tubes. If your Eustachian tubes get infected, it could lead to Eustachian Tube Dysfunction (ETD) which requires a lot of time to clear up.
The first few times you do this, it may feel uncomfortable to have saline and water up your nose.
