This (waves of dizziness) have occurred with me since having COVID. I still have dizziness upon standing (accompanied by what feels like rubber legs…legs just don’t want to move and it feels as if legs are disconnected from me). Vertigo also occurs, especially during flights. The vertigo is so bad shortly after the off that I literally must grab hold of the seat. It feels as if I am spinning. The sensation lasts until the plane levels off close to the cruising altitude. The first few times it happened it was so severe, I felt as if the plane was spinning. Now I’m able to work thru the sensation, but it still occurs. This never occurred before having COVID and I have traveled quite a bit.
