I had an episode in October of 2023. It was so bad my eyes were twitching. I went to bed, that only made it worse. I had awful nausea. I didn’t go to the ER, but to my ENT who ordered an MRI (only thing that proved was that I have a brain). I also went through vestibular function testing and a hearing test with an audiologist. That was not fun. I have what’s called vestibular hypo function in my right ear. I have exercises that I must do several times a week, or I will have a dizzy spell. Riding my bike helps. Vertigo is a sign for many things. Fortunately, we found an answer, unfortunately there is no cure. Maybe a visit with your ENT will help.
