I was sitting on my front step last night with my girlfriend, and I stood up only to hit my back/side(not my backside) on the bottom of the wooden hand rail.

It hurt super bad. When we got back inside I showed it to my GF and her eyes got really wide and said "It's bleeding!" It wasn't dripping blood, but it was still oozing out. So we cleaned it up and what not, but it still stings.
