I Dropped A 45 Pound Weight On The Center Of

I dropped a 45 pound weight on the center of my foot. The weight was a quarter shaped circle. I was lucky the shoes had good cushion in it but I still felt all the pain. I had a bump across my foot, so I iced it. So now the swelling went down I could see a vein that looks like it has been sliced in half! What should I do.
