@tracey8 Yes, I had vertigo for a period of time for about a month. It subsided and didn’t come back. This happened about 27 years after my radiation and during flair ups of MS and autonomic Afferent Baroreflex Failure (ABF) symptoms. The vertigo occurred when I was in a prone/sleeping position, throughout the night/morning when I moved my head or tried to sit up. I was told by my neurologist (who I trusted) that it could be transitory, and it turned out he was correct. Cognitively, I’m somewhat slower over time.
