Possibly broken foot?

so today when I was helping my barn manager with her horseback riding camp one of the horses was acting up. she was prancing around and landed right on my foot, hard. she then twisted on it, hard. and pranced off. I was fairly certain it was broke when she did it but i didn't say anything and kept going. my foot is fairly swollen but just over the middle of it. its kinda bruised but not too bad. I wouldn't be worried except i cant really move my toes or ankle and it hurts pretty good to walk on it. think its broken and i should go to the dr or just stay off of it for a while? thanks!
