Hi.
There is a possibility that your condition could also be related to a vestibular disorder, such that sudden changes in head direction would lead to symptoms of dizziness, blurring of vision, and blacking out. However, this does not rule out other possible causes of the condition such as blood pressure abnormalities, or a more severe presentation of migraine.
Consult a physician to evaluate your symptoms to determine what may be causing your condition.
Good luck.
Hi,
I would suggest you to get your BP checked as soon as possible to rule out high BP as a cause for your symptoms.
I am not a dr., that being said, you need to have an MRI to see if there is anything else that might causing these blackouts. Whenever you have new symptoms and are blacking out, that causes concern. Good luck
