I had pretty much the exact same symptoms you are describing. I am also in my mid-thirties. It was extremely uncomfortable. It was disorienting enough that whenever I experienced it (which was daily) I would start to spiral out and have a near panic attack, i.e. it was extremely anxiety inducing. It was so uncomfortable, sometimes when I stand up (1 year later) I still brace myself for it.
I wish you a quick recovery.
For me on the other hand there were no particular issues after the virus, though I certainly don't have the same strength I had before. Haven't yet vaccinated, as I've been instructed by my GP not to yet (still have ~600 bau), my next test is in 10 days. Still researching which vaccine is safest.
Way before COVID, I got vertigo for a weekend, caused by a cold. Apparently viruses can cause the fluid in the ear to change in viscosity.
For me that induced vertigo (really bad "spins" for two days), for you it could be less severe but longer lasting. As I understood it, it can be caused by any virus (unclear about COVID's relationship with it) and will likely go away.
While it was happening, I drank extra water and any time the spins got out of control, I'd sit down and take some deep breaths. It's easy to cope when it is just for a weekend. Best of luck to you.
P.S. Always best to check with a real doctor.
I've started experiencing some balance issues recently and am otherwise healthy as far as I know. I am mid-thirties, double vaccinated and boosted, and may have had COVID but don't have a positive test to confirm it even though I had some mild symptoms consistent with the Delta strain.
Has anyone else who has either received the vaccine (I got Pfizer) or had COVID experienced a new feeling of instability when walking? Not necessarily a room-spinning vertigo but more akin to feeling like a toddler learning to walk or a little drunk. It seems especially noticeable when I'm walking and turn my head to look to around.
I've always felt sure footed and this slightly off kilter sensation began about 2-3 weeks after my booster.
