Hello dloos,
I'm from Greece (so forgive any language mistakes 🙂 ) I've recently read your post while I was searching for some answers about my self and I'd like to share a couple of similar stories.
Long before Covid a guy that I knew, after a short roadtrip he lost his hearing to one ear without any apparent reason. Doctors couldn't find anything wrong and said it was due to anxiety (..not!). After almost a year he obtained like 70% of his hearing back without any treatment. Second case, my husband after a flight his ears clogged for many months and couldn't do anything about it. Doctors have said that there was nothing wrong. I think half a year later his ears just unclogged by themselves, but since then, every time he gets really upset they get clogged again for a few minutes and that really frustrates him!
And now my story. Right after covid recovery last Chrismas, I woke up with blurry vision, tinnitus and headache behind my eyes. Those headaches continued almost daily for two weeks and after that I had a heavy head feeling and light dizziness for another month or so. To make things worse I've developed sensitivity to light and hyperacusis (to a moderate degree). It's four months now and to make a long story short, I'm all this time back and forth between ofthalmologists, acoologists, ent and neurologists without any luck. I did all sort of tests (even lumbar puncture and mri ) but everything came out clean. The only things that I know for sure, is that Covid flared up an old eye problem that I had and thought I've had recovered from (spots on the cornea due to an old conjuctivitis) and revealed the latent hyperopia that I didn't know that I had. Those explain, kind of, my vision problems and because of that I ended up in three months to depend totally on the glasses that I once only used for tv... Still, no explanation for tinnitus and hyperacusis. An acoologist said that maybe it is some sort of vestibular migrains due to the virus and that will fade over time. Will see..
What I would suggest for you is to focus on your vision problem and try to short this out since the other seems a dead end. Visit a good neuro ophtalmologist and ask (demand) to find you some lenses that clear up your vision. Then make a pair of glasses and wore them all day until you get used to them. If that contributes to improve things a bit for you is a win, isn't it? Maybe the eye problems and the ear problems are not connected, so don't expect to find a cause/treatment that solves everything at once. What do you think? I'd like to hear your opinion 🙂 Also what's your age? Have you thought about perimenopausal symptoms? They start for some women in their late 30's and they can really mess up your life (I know..I'm 44)!
