When playing football i hit the top of my foot off the bottom of someone else's, i immediately had pain and now hurts to walk on and put pressure on ?

Sprain or fracture: A doctor cannot distinguish a sprain of the joints from a fracture of a bone without an x-rar. Get one. A sprain needs less support than a broken bone. Walk on a shower clog or in a sabot till you can get diagnosed.

Hard to say: Multiple possibilities, I would not hesitate to be seen and evaluated, particularly if the pain is severe or there is associated swelling.
