Possible Bone Bruise? What to do about it?

I was at the local gym about 12 days ago, and I juggled by soccer ball for 3 hours non-stop. When I got home, the top of my left (dominant) foot hurt really badly. I still play soccer on thursdays, saturdays and sundays, and my foot still hurts. It hurts right on the medial end of my first metatarsal.
