It's been blocked on and off since I had covid in 2021 😬
It gets worse every time I get a cold or my hayfever is bad, so I assumed it was a middle ear thing. Had a phone appointment with my GP about it when it first started and was advised to do steam inhalation and use otrivine nasal spray, so that's what I've been doing when it blocks and eventually it clears. My ears never seemed very waxy and due to it being linked to congestion I never thought it might be wax.
But about 3 weeks ago it blocked and just wouldn't unblock. I've been almost completely unable to hear from that ear since and it's been misery, so disorientating.
Anyway I thought in desperation last week to try wax removal just in case and got some bicarbonate of soda spray, when I tried it my ear literally fizzed and popped and seemed slightly clearer so I've been doing that twice daily for 5 days. This morning I thought I'd give it a rinse with a bulb thingy and some very slightly salty water and OMG the gak that came out 🤢 I thought it would never end, and then one really big stringy bit (like a ribbon of dead skin) came out and all of a sudden I could hear again and my head stopped feeling faintly swimmy. It took 3 x 500ml jugs of warm water (teaspoon of salt added to each) though, I was rinsing it for about 15 minutes til the water came out clear.
Everything is so loud! Its obviously been far worse than I realised for ages 
Once I get used to everything being so loud again I'm going to do the other ear, which I thought was unaffected but now this ear is properly clear I can tell that the other one is a bit blocked too.
