I wear one BTE hearing aid in my left ear.
I have noticed that I am getting air trapped behind my mold and I cannot equalise the air that is trapped behind it. This is affects the sound. I have tried swallowing and holding my nose but the mold is a tight seal and makes no difference.
When I have my hearing aid out, I find it hard to pop my left ear. The right ear pops every time without fail, but the left ear does not. I have to try other methods like drinking water while holding my nose and that works some times.
I wonder what this is? When I do a sinus/nasal rinse my left ear is fine at popping for a few days.
This has gone on for many years.
