I'll preface this post by saying that I've got a "normal" amount of ringing tinnitus in both ears. Annoying, but not tragic (or surprising, having played one too many concerts without ear plugs.)
However, my left ear is a little more messed up, and since the last couple doctors could find nothing wrong with it, j thought I'd give this forum a shot.
Maybe about 7 months ago, I was in the shower, when I left water go down into my left ear, I pushed it out (similarly to how you pop your ears) but not all of it went out, and I could feel it "slosh" back into the ear, so I pushed it out again.
When I got out of the shower, I noticed that my hearing in my left ear was muted. I rubbed my thumb and index finger together and indeed, there was a sharp drop in the higher frequencies.
This hasn't gotten better over time. I still can't hear the higher, "shimmery" range in my left ear.
Still, while annoying and scary, it still wasn't debilitating. In the last couple months however, my ear has been "warbling" in response to louder noises. If I or somebody else is speaking loudly, if I'm listening to music, if I'm in a space with a constant murmur of voices, my left ear will "warble" on response to the sound, like I was listening through a broken speaker or something.
The doctor looked in my ear and said she couldn't see any physical damage and have me a pair of foam ear plugs...
