Does Concussion From A Roller Coaster Ride Cause Dizziness And Nausea?

I visisted an amusement park this weekend and rode 4 rides total, all roller coasters. After the last ride I felt different . A little lightheaded, very slight difficulty focusing, mild nausea. These symptoms continue now over 10 hours after my last ride. Is it possible I have a mild concussion from the jostling from the rides?
