look into an anti-fungal cream from a drug store. if you did not bruise your foot then you don't have a bruise. i had this on my back and found that it was a fungal rash that i had been treating. it was that ever lurking athletes foot. contrary to popular beliefe the fungal rash can travel all across the body and only gets worse. i would throw the cream on it folowing the instructions on the packaging and monitor it. odds are within a week it will become both lighter and smaller and eventually go away. advice: spread the cream far beyond the spot becasue fungi lurk beneath the surface i would put the cream at least up to the ankle. the creams are expensive but they all work the same. just stay away from the powders and sprays and stick to the cream it is more of a hassle but you get more for your money and i think that they work better then the spray. anti-biotics will not work nor with bleach scrubbing or any other home remedy that one can come up with. also you do not have to be an athlete to contract this something as simple as leaving dirty socks on too long or not washing your socks frequently can cause this. just try to wash everything you have and maintain a regular basis of hygene and continue cream use for at least two weeks after the rash is gone. if this does not show improvement within the first two weeks go to the doctor and have it looked at. it may be something more or even better something less. good luck!
