Swollen Belly Button Lump PAINN!!?

I got punched in the stomach the other day pretty lightly by a buddy, ever since I've had what feels like a killer bruised area at the top part of my belly button.. when i push down i can feel a hard bump and it shoots pain in that general area... really irritating everytime i goto sit down i can feel it, everytime i stand up, everytime i roll over in bed it wakes me up.. if i keep messing with it and pushing on it it starts to feel really achy and sore for like 10-15 min .. i dont feel like going to sit in the lineup at the doctors for 6 hours so if someone can tell me what the hells going on that would be nice... i dont feel sick or anything i feel fine just annoyed and impaired lol..
