Drunk Guy + Melted Snow Slush = Me With A Swollen Bruised Knee

So I'm supposed to start my running tomorrow and I have been super psyched about getting to this point and then last night happened. Walking in the Ville to the Purple Pig, about to cross the street, some drunk guy can't figure out how to walk and slips on some snow slush and decides that I'm going to not let him fall. He ends up pushing/pulling me down to the ground with him and I slammed my knee into the pavement..OUCH! It hurt so bad the rest of the night, I thought it was bleeding but couldn't look because my pants were tucked into my boots. I get home all soaked and hurting and just decide to go to bed. It hurt all through the night to where I cant even lay on it. I wake up to it throbbing and look at it, the whole bottom of my knee is black and blue. Not horribly swollen but hurts like no ones business. I'm still going to try to run tomorrow regardless because I have a deadline and I need to meet it. At least the running isn't super intense or anything but I know its probably going to hurt. Lame.
