Not feeling so well. Can you help?

Anytime you injure your head, you risk injuring your brain, also. It is kind of like bruising your brain and if it bleeds or swells, even a little, the pressure can cause some of the symptoms you are experiencing, if it swells a lot, a person could die. I think you should have it checked out by a doc. Check with your family and friends about how you've been acting, if they've noticed a significant change, take them with you.
