I am a 53 (almost 54) female 5'2" and I weight about 123 lbs. I feel like I get dizzy off and on not spinning dizzy more motion kind of dizzy. If I move my head too quickly or walk on a treadmill, or ride on my husbands motorcycle. I did have a stapedectomy performed in my right ear about ten years ago. My left ear is about 50% hearing loss now. what do you think this is from.
