I've had vertigo three times. Medicine was not a cure for me. They had to shake my head around and then put a neck brace on for 24 hours. It cost me my Goldwing. I traded it for a BMW Z4. My problem was supposedly arthritis of the inner ear bones and they would get stuck. When they shook my head and I wore the brace for 24 hours it went away. I hope they find out what has caused yours. I know exactly how you feel. The procedure was done at a place that did hearing tests.
