My big toe has a big bruise.. what should i do to make it better?

so i was walking barefoot for about an hour because my high heels were hurting me. and now i have a bruise all the way around my toe. it hurts. i know i didn't get a piece of gl stuck in there because i would have felt it. but i was walking on little pebbles and rocks.... could i possibly have a fracture?? i can move my toe fine though.. so i'm not sure.. and it doesn't hurt when i wear my gym shoes. it hurts when i try to walk barefoot anywhere. please help... the bruise is getting worse.. its really hurts and i don't have health insurance so i really do not want to go to a doctor...
