Couple of basic questions...

Do you have any blurred or double vision?
Do you feel dizzy or nauseous in any way?
Do you have any pain any where else...ie, neck, shoulder, back?
Do you have any tingling in your arms or legs?
Do you have any slurred speech? Can you say the following...."You can't teach an old dog new tricks." without sounding like a drunk?
Can you see what your pupils look like, by looking in a mirror? Does one look bigger, or smaller than the other?

If you can answer yes to any of the above, you might want to get checked out.

If not, it may just sound like, as you said, "clobbered yourself pretty good."

There are a lot of blood vessels in the head/scalp area, so even a small lacerations will bleed profusely. So that may be way you're seeing "lots" of blood.

But even still, if you're not quit sure, and your brother is going to be late......go get it checked out. Your brain bucket is nothing to take lightly.
