Holy fuck. This sounds exactly like what happened to me a year ago. One day, it came out of nowhere and I thought I was having a stroke. I was too dizzy to do anything and thought I might actually be dying.
After a month, it got a lot better but I still constantly get bouts of it, especially when I bend over. It makes playing with my kids incredibly difficult at times.
If it turns out I have BPPV and my doctors didn’t think to test me for THE MOST COMMON CAUSE of vertigo, ima be… unsurprised 😅
I'm sure you've already looked up the exercise that helps reset those crystals, or at least i hope so This happens to my wife too, and it does the trick but i hear it doesn't always work. Does that method not give you relief?
The first time I encountered this, it scared the shit out of me. Only by rationally eliminating possibilities was I able to calmly dig in, learn about the Epley Maneuver, and get some relief.
It still pops up on occasion, but a couple of rounds of the Maneuver and I’m usually back to normal.
John's Hopkins also discovered Superior Semicircular Canal Dehiscence when resolution of CT scans became high enough to detect fine cracks in bone around the tegmen and all that. SCD also worth a read. Sound doesn't properly dissipate and instead triggers the cells in the canals leading to sound-induced vertigo and supranormal low frequency hearing (being able to hear your eyeballs scratching against your eyelids etc). Before CT scans got good people got misdiagnosed with all sorts of anxiety type disorders
I may have experienced this. A couple years ago I was getting over a cold. I blew my nose and instantly experienced severe vertigo. The room looked like it was spinning and it felt like I was on a boat in the middle of a rough storm. I nearly fell over. It took about 15 minutes for the sensation to fully expire.
I wonder if that's what happened to my dad... His hearing has been going bad for years, but right around when it started being noticable that everyone in the family was telling him to get hearing aids, he also was getting random bouts of vertigo.
Can't rule out vestibular migraines. I didn't even know I was having them until I got a really bad headache with the other symptoms. Doctor was able to confirm it as that but it took quite awhile.
