I get similar problems sometimes when my allergies are acting up. I flush my ears with peroxide and they're good for a while....and later removing myself (peroxyde and water) a plug of around 1cm! But like said before, I will refrain to attempt anything by myself and let the professional do its job next Tuesday.
Most people are very reluctant to clean their ears with peroxide. I don't get that. I grew up on a farm and it was a common practice for kids and animals. According to what I've been able to find online, there's no reason to fear the peroxide wash.
I've heard similar stories from a few people. Audiologists say everything's fine when it's obviously not, so they end up flushing their own ears and discovering that their audiologist was a quack.
Guys, I used to do the same thing (almost). Used a product called Ceremol to loosen up earwax (which didn't really work) followed by blasting out the wax with water from a syringe. I used to wait until there was such wax build-up that I was almost deaf in that ear before performing this procedure (which is crazy when you think about it) because I didn't want to overdo it.@TMe : I understand your point has I always use water and peroxyde to unclog earwax. But the last two times (may and this week) my left ear didn't liked it at all as I had episodes of hearing loss for a few days after. Probably a mix of irritation, clogged Eustachian tube and maybe allergies.
It looks like sea water spray was the most beneficial trick after cleaning
