There are “crystals” in your ear that help you keep your balance and keep the room from spinning. They can get knocked out of place. See an ear doctor. One who knows how to manipulate your noggin to reset the crystals.
I did. They didn’t see anything wrong, either.

Yep... Called BPPV, I was thinking the same thing about several of the replies here. I have had this happen many times and gives me vertigo and temporary tinnitus. There are self help exercises that can help, and seasickness medicine can help.
