Is it normal to go blind and really dizzy. Sometimes it will happen after I stand up but not rite after it takes about like a minute or two. And the one time it happened I was waiting for food with my friend in sheetz and all of a sudden me vision started to get blurrie until I cldnt see anything and my friend took me outside to sit but I didn't get my vision back for like 5 minutes maybe a little longer. And it has been happening more often latly. Some one said it could be health issues and it scares me because I have no idea.
