So, when I was about ten, my vision blacked out for about ten seconds. My whole body went numb, and I had a tingling sensation and needed to sit down until my vision cleared and I found I could move without pain. I went to the doctor's and he told me it was nothing, that it would pass. Skip to now. It did pass until about two weeks ago. They came back with a vengeance, my vision blacking out for easily twenty seconds, the tingling spreading everywhere, and being forced to hold onto something until I could walk again. Then today came. This morning at about 530 I had gotten out of the shower and was putting acne medicine on, when my whole vision went black, the tingling was unbearable, and I held onto the counter until my strength left me. I sank to the floor and held my head in my hands for a good five minutes before the black out left me with a headache that could cut diamonds. All today, I've been fearing another attack like that will happen. I am on no medication, have no health issues, and live a perfectly healthy lifestyle: exercise, sleep, and eating properly. The attacks come randomly, and without cause, never from standing up too fast or something like that. Here's where you come in, dear reader. Have you had this same sort of experience? If so, have you gotten treatment or a diagnoses on it? If no to both of these, any advice you have would be appreciated.
