Yes, get someone to take you to the doctor!
Also, have the doctor check your eyes, especially if you're nearsighted. Hard blows to the head can detach your retinas, and possibly cause blindness if you don't seek treatment right away. I'm probably overly paranoid because I had a detached retina, but it's something you DON'T want and so many people don't know to have their eyes checked out when they hit their head.
I think you'll be OK, though.

Feel better soon!
