Hi,
It is important to consider the possibility of epilepsy. I would suggest you to undergo an EEG exam to confirm the diagnosis of epilepsy.
Another possibility that can be considered is migraine. Migraine can cause lightheadedness, blurry vision and black outs.
Hope this helps!
sounds like your having epaleptic seasures in some part of your brain,and they have not found it yet,,,i almost guarantee thats whats going on.
i bet if they put you on some meds ,,just for trial and see,i bet you would get better asap,,,,even if they ruled it out,,,im telling ya,,,,go have it checked somewhere elce.
