My dad was sitting at the bar. He started feeling light headed, then he fell off a bar stool and hit his head. He passed out. He woke up confused, clammy skin and is having problems remembering the day and where we were. We re home now. He s still sweaty and pale, trying to remember. Please help. He only had 3 beers, which is very normal. He was not drunk. He s also been having bad migraines all this year.
