My Eustachian tube function is poor, and my eardrum is not in good condition.

Since I was young, my Eustachian tube function has been poor, and I have always had otitis media.

Maybe it's because of the rhinitis as well, making my nose stuffy and feeling worse.

Is there a way to relieve nasal congestion and also improve Eustachian tube function?

I'm very worried because my hearing has also significantly declined.
