I was playing soccer and someone stood on my foot. i dont think it's broken but it hurts everytime i walk for long periods or do any exercising?

Sounds: like a BRUISE although a hairline or "chip" fracture cannot be ruled out without a simple xray....Since it appears that you do not wish to REST/ICE/ELEVATE perhaps you should seek the xray to know WHAT you are dealing with. A contusion (bruise will be better in 10 days to two weeks a fracture 6-8 weeks!! BE WISE BE WELL Hope this helps Dr Z
