If you've been in a car accident in which you hit your head, but seem to be more or less fine, you may hope that whatever bruise or bump that appears will be the end of the story. However, brain injuries can be sneaky, and sometimes don't make themselves known for some time after the original injury. So how do you know if your brain was injured more than you may have realized?
Whatever your initial injuries seem to be, it's important to see a doctor as soon as possible after your crash. This is important not just for health reasons, but also for documentation. If you end up pursuing compensation for medical and other expenses after a car accident, it is in your interest to have a paper trail of evidence starting right after the injury that demonstrates the timing and extent of your injuries.
