Sounds pretty typical for ear infection, maybe more in the tubes that are between ear and nose. I had one earlier this year that was very similar to yours. I did get antibiotics for it after about a week and it still took nearly two weeks to clear up completely.

It’s just the foam bullshit thing, you’re good

Not sure if this works, so testing

Used to buy this beauty in 4-packs, but unfortunately has not been available in that form for a while.
