Is it a bruised rib or bruised muscle?

so today at a soccer game i tripped on a dip in the field, and i was right by the goalie, so her leg, mainly her knee, went right into my right side. it knocked the wind out of my right side immediately, took a while to get it back, and my ribs hurt a LOT. i can't really do a bend backwards, and bending forwards got a little better, twisting hurts horribly too. taking deep breaths really hurts too, inhaling and exhaling. a trainer poked around at the ribs, and one of them definitely hurt way more than the others. it's been about 3 hrs, i've taken ibeprofun, and its still a big lump where its swelling along the rib. it hurts just sitting around too, and while i sit up or trying to keep my back straight. i just don't know if it's a bruised rib or a muscle, and what to do about it. thanks.
