Vernon, I HAVE this disorder!!
I've had it since I was 19 (30 now).
Its name is Patulous Eustachian Tube. If you search in the net, you'll find many things about it.
Sensation of fullness in the ear, autophony (the worst thing for me!!), incredible yawning(!!)

, desperate cherishing to lay on a sofa, tiredness.
After many years of discomfort, mixed with ENTs who did NOT

understand how annoying this can be,

I met an ENT who tried with two actions: he opened my nose that was not perfectly open and he put a little tube in the eardrum, that compensated pressures.
IT WORKED!!
