Hi, I am a 54 year old woman. In the past 4-5 months I have had 4-5 episodes where suddenly, out of the blue, I become extremely dizzy, I mean the room feels like it s spinning. Two of those times it was so severe that I was down for 24+ hours. when it happens, I become shaky, and sweat profusely for around 2-3 minutes. I ve been checked for a possible ear infection, did not have one. I have no clue what could be bringing these dizzy spells on. If you could give me any ideas, I would greatly appreciate it.
