Hearing loss, loudspeakers sensitivity, muffledness, slight diziness..

Hi everyone:

I am new here, wanted to share my story so maybe some-one can relate and share some light.

I am a 35 year old male, I used to do heavy use of headphones and earplugs for many years. So in December 2020 I began having having issues, muffledness, slight loss of hearing and pain in ears, throat and sinus. I went to an ear doctor, which gave me some corticoids, and very quickly I recovered, although from that moment on, I couldn't use headphones, or earplugs or go to places with loud music, as I would temporarily lose hearing, so I just stopped doing those.

In December of 2022, I had the great idea of going to a bar with loud music with my friends. After that, I was several weeks with pain, muffledness and loss of hearing. Also I develop this super sensitivity to noise coming out of loudspeakers, so watching films or listening to music was a no-no. I eventually recovered.

The a few months ago, I was exposed to some music and again I began having all the previous symptoms. Ear doctor sent me corticoids that I used in drops via my nostrils. That did away with the symptoms apparently, but then I listened to music and was back again, and now also with a loss of hearing of sounds that are in low decibels, so it is difficult to follow some conversations, or specially in places with background noise like if there is many people talking at the same time. Now also I can't really watch movies, unless volume is super low.

I went to ear doctor and he run a CT-scan, which showed I may have superior canal dehiscence syndrome, but he said he would be reluctant to do surgery as I hardly get dizzy and my VEMP test was "kind of a positive", or so he said. He said he saw a 50% chance surgery would do me any good. Also said there's a 2% change surgery gives me further loss of hearing.

Can some-one share with my their thoughts? Has any-one had symptoms like mine and can provide advice on what to do? Regarding the super sensitivty to loudspeakers and loss of hearing for low decibels sounds, any guidance to know if it is permanent or to try to improve?

Thanks
