So about two days ago I was getting out of my car and i hit the top of my head on it. It hurt really bad for a little bit then went away. Now, its been 2 days and i can feel a pretty big bump on the top of my head and it is pulsating. When I stand up I kind of feel like I am being pushed towards the ground (weird type of dizziness) - different then the constant rocking I feel with the mav. Do you think I should be concerned about this? or do you think I just need to wait until it heals?
