What is wrong with my ear ( and nose and nose and throat)

[hollyberrytree]

I don't expect anyone to diagnose me but any clues will help please.
It's gone on for months.
I have seen the GP a who said fluid "bubbles" behind my eardrum
However the ENT specialist who had the fastest look in the world said no, the bubbles the GP saw were scarring.
I'm off for a hearing/ pressure test.
My ear feels full like it needs to pop.
ENT doc told me not to try to make it do anything and let it settle.
I wake up with full sinuses in my cheeks, I have post nasal drip.
I don't clear my throat or cough.
I have tinnitus.
I'm not unwell but the fullness is annoying and I'm fed up.

I think I'll go for a second opinion

It sounds like ENT have asked for tympanometry , this is probably what is meant by the pressure test. It’s quick just takes a couple of minutes, they might do a hearing test as well. Presumably they’ll look at the tympanometry traces which indicate how well your ear drum is moving, if there’s fluid behind the eardrum/in the middle ear space the drum might not move much. When they have the results I expect you’ll get some idea of ways forward, you might not need a second opinion then.

ENT doctor was so dismissive. It was as if all my symptoms were in my head and he implied that if I left things alone they would clear up.

( no coughing or trying to pop my ear by holding my nose and blowing etc, which I know I don't do, I'm a teacher, if I had any sort of habit I'd never hear the last of it!)

Thank you for replying
Specialist actually said after I get the hearing test
' we will know who is right or wrong, me or your GP'
He seemed convinced there was nothing there.
