Hi there. About 2 hours ago, I was outside at work, and I slipped on the ice and fell hard; hitting my head on the curb. I fell unconcious for about 1 minute(?). There is no blood. Since then, I have been feeling very dizzy, sick, confused, and I can't stand properly - without losing balance.

I don't know whether or not I have seriously injured myself, or if it is just a common reaction to a hard collision to the head.

What would you reccommend? Is it worth going to the hospital to get it checked out? Or should I wait until tomorrow, to see whether or not I am feeling any better?
