Badly bruised or broken?? Please help?

Yesterday (january 3) I dropped a heavy metal stool on my right foot. It hurt really bad. There's now a bump on the top, middle of my foot. And a bad bruise by my big toe. The pain and went all over my foot in different places. It hurts the most when I'm not walking. It will randomly hurt when I'm sitting with it up on a table or in bed. The worst area of pain now is the bruise by my toe. It's not on my toe. But I guess you could say bellow it? If you know what I mean. Not on the bottom of my foot though. It's very sensitive and hurts to walk sometimes. Putting a sock on this morning hurt. Please help! Thanks (:
