I had a bout of it in late-2022. Went to the emergency room and they couldn't find anything wrong with me that was an 'emergency' (no stroke or cardiac issue, blood work OK, CT scan of head OK), did the Epsley maneuver (sp?) on me twice with no relief (I threw up both times as it makes the dizziness even worse). Admitted to the hospital for a few days and cardiologist and an ear-nose-throat doctor could only come up with a possible inner ear infection and I got sent home with meclizine (useless). It took about a month to get comfortable driving a car on a limited basis, and about three months before I felt comfortable on a two-wheeled bicycle on a street (balance issues). So far no recurrence of the problem and the balance issues are non-existent anymore. The doctors said it could come back in the future.
