Full Blown Ouchie

So, I'm searching for my shoe that flopped off up under my counter at work. While I have my butt in the air, and my head down below, I finally find my beloved shoe.

WHAM!!! Full force hit the back of my head on the counter. I thought I was going to die. Please pray I didn't juggle some important stuff up there in my head. My whole neck is now hurting. :(
