My wife has been dizzy and seeing blurrd and double vision for four days now. she has had several blood tests on two separate days, along with an cat scan of the brain and an x-ray. Her symptoms of dizieness are longer between ocurances within the past two days (including today as one of the days). Doctors (3) have found nothing and do not know what is wrong. Physical and couridinaiton tests (basic finger to nose and finger to fingers) have been normal, she is slow but accurate. She is sechuled for an MRI with contrast wed. of next week, (whitch was sechuleded befor any of this happened. MRI was for possiable parkensons (father had shaking of hands, which she has had for around three years also). Any other opinion would be helpful I have even asked if anything in house could be at fault, (mold, dander we have a dog) no seems to be the answer.
