it doesn't happen very often, but probably it happens about once a month. So what has been happening is that i feel fine and then in the next instant my head starts throbbing uncontrollably and my vision starts to fade out then i go complete blind, but 30 seconds later i'm fine. Is this a form of migraine because i thought they normally lasted at least half an hour. Please respond if you know what this is?
I get this. I have been blind for up to 20 minutes. Also my vision goes blue for hours. Very scary but neurologist shrugs it off
so you have no idea what this could be?
