In March, 2022, I had my first vertigo episode while lying over the side of the bed looking for our cat beneath the bed. It was the full-blown thing with eye-rolling, disorientation and nausea. I called my primary care physician and he asked me to come in for a visit later that day. After a quick check-up he asked if he could do a test to check for a condition called "positional vertigo". He said that if I had that type of vertigo the test would probably cause another episode and while it's not a fun experience, we would know what's wrong. So, he did the Dix-Hallpike test, normally used to determine which side is affected, and WHAM another episode, worse than the first. It was classic BPPV.
So, long story made short - he referred me to a vestibular rehabilitation program at a local hospital. He said that at my age (73) there might be other issues that could affect balance and he preferred that I get a full work-up. I learned that I did have several other age-related balance issues that would probably get worse over time and the physical therapists taught me exercises to improve those things.
Regarding the BPPV, one attempt at the Epley maneuver to reposition the calcium carbonate crystals worked for me. I haven't had an episode in over a year. I was cautioned that the condition can return if the inner ear starts shedding crystals again but I haven't experienced that and hope I don't, of course.
The crystals can be absorbed in the semi-circular canals over time but the simplest thing is to get an Epley maneuver performed. It's not a comfortable thing, and you'll get some vertigo at the beginning and end of the maneuver, but that's just proof that the crystals are on the move from where they don't belong back to where they should be.
There are lots of good resources on the internet including videos on YouTube. I wish you well.
