Is my wrist sprained or something else?

Ok so here's the deal, I fell over in indoor soccer a couple of times this afternoon (about 4hours ago) and my wrist hurts under the thumb and under my palm, it's a constant aching pain that absolutely kills. I have bruising on the top of my hand, redness under my palm and my wrist is warm to the touch. It also hurt more when I bend or flex my fingers or make a fist or when I turn it. What have I done? Do I need to see a doctor?
