Things I've learned from roller derby #2

How to tell if you have a concussion:

Did you hit your head?
Are you dizzy?
Is your vision blurry?
Are you confused or disoriented?
Do you feel nauseated?
Are you puking?
Did you see stars?
Are your ears ringing?
Do you feel off-balance?
Is your helmet cracked?

If you did hit your head, and you answered yes to more than one of these questions, you may have a concussion. If you hit your head, symptoms might not appear for 12 hours.
Yes, I learned this the hard way. No, I didn't get a concussion this week. Thank heavens.

PS- if you think you might have a concussion, go to the Dr. For real.
