@turkay1-- If you have so many issues with your ears during flights, you might have blocked Eustachian tubes, partially or completely. You need to see an ear specialist about this.
I have partially blocked Eustachian tubes, they're not in very bad condition so I manage changes in air pressure with nasal sprays, gum and a little trick that a nurse told me. I hold my nose closed with my fingers, keep my mouth closed and create pressure inside my mouth. It causes a popping sound and opens up my Eustachian tubes. I do this occasionally during flights.
I also chew gum most of the time and I use saline nasal spray before the plane takes off and lands. Nasal sprays help keep the Eustachian tubes open.
