So today at around 1:00pm I hit my head really hard while getting out of a van, I was standing up and thought I was bending down enough to not hit my head, I was wrong. I was exiting pretty past and hard and then whack, hit my head. I didn't pass out, but there was a lot of pain as soon as I did it. After a bit it went away and a lump on my head developed that hurts when touched.
It's 11:00pm at the moment and I'm too scared to go to sleep because I'm worried about me having a concusion, and what will happen if I fall asleep.
Any advice on what I should do? Thanks.
