I have been experiencing dizziness all thru the day and evening. I am 89 years old in very good shape. This has happened before about two months ago and gradually went away. What bothers me this time is that one morning I was watching television and there was a portion of the picture that was not visible, and that gradually got better during the day. I never suffered from migrains, and do have a blood pressure problem but it is stable when I check it. I am very aware of my body...I expect to go see an ear doctor if it doesn t bet better and than perhaps a MRI brain scan because I don t like that reaction of a temporary loss of vision in my left eye. I do have glaucoma of my right eye which is under control. What do you suggest? My diet is excellent and I exercise every day and am in exellent shape. I weigh 128 pounds and 5 feet 7 inches tall.
