I have a similar story to all of you, expect my accident happened while freediving in early May 2016. I'm a healthy 35 year old with no prior issues with hearing at all. I did 1-week of freediving in Bonaire during May 1-9th. I apparently forced my equalization too hard and one day I noticed muffled hearing and slight tinnitus. I just thought I had water in my ear or something and that it would clear up eventually. It never did and I kept freediving, often to depths of 100+ feet for 2 minutes at a time. The only thing I can think is that I forced the equalization a few times... also I was wearing a hood and it is possible that there was air trapped in the hood (always punch a small hole in hoods). In any case, I immediately saw an ENT when I got back to Michigan. Same story, I had hearing loss in my left ear only. Anything above 5,000hz was very hard to hear. Right ear was perfectly fine. At first my only symptoms were the hearing loss. But soon the tinnitus came on.... then got progressively worse. Then I started to feel dizzy sometimes, even when I was sitting still. Then I became very sensitive to loud noises. Anything loud would pretty much make me dizzy and nauseous. Right now i'm avoiding loud places like restaurants. Noises like plastic bags being crumpled and dishes clinking together make me crazy. I'm also very sensitive to pressure (think opening your window in a car). It's only been 3 weeks, but so far it hasn't gotten any better. This is very scary and I can only hope it gets better. My quality of life has suffered dramatically. It makes me want to avoid going out. As far as what's wrong, my eardrum is fine, so it's something in the middle ear. Not sure if partial tear or complete blowout of round window.... i don't think so because i never really became dizzy or anything when i was diving. My best guess is that i maybe have a slight tear of the vestibule. Or, just some form of general inner ear barotrauma. If my story resonates with anyone, please let me know. My family/friends have no idea what i'm going through and I feel like i'm suffering alone.
