Suggest Remedy For Swelling In Hand

I put my right hand on a bench to brace myself. I put maybe 50% of my body weight while doing this - I'm only 119 lbs. Next thing I know is the top of my right hand hurts really bad for the last 16 hours. Flexing it hurts. Pain is localized above the ring and pinky finger and also on the flip palm side. It's slightly swollen and hurts if I grip or flex or put any weight on it. Should I go get it looked at?
