Last night my roomate and I were drunk, I passed out. He later attempted to wake me, and kidney puched me to do so. I was too drunk to realize this and fell back asleep. I woke up today with a sharp pain on my side/lower back. I does not hurt very bad when still. But when i move or do anythign using that region of my body it hurts. Do you think this could be permanent damage? Or am I worrying for no reason? I didnt pee blood or anything today, it doesnt hurt to pee either - Help plz thanks
