I bruised my foot badly playing racketball in the middle of April and it still hasn't healed yet. Suggestions?

I went to my doctor once in may and he prescribed me antibiotics, but that didn't work. I went back in June and he prescribed me different antibiotics, still no luck. I'll be going back in a few days to get it checked out again. I believe he'll be giving me a shot in the foot and he said that should hopefully get rid of the pain. I'm just getting very paranoid not because it has been over 2 months and it's still not 100%. This fall I want to try out for the Michigan State track team and I should have started training in the beginning of summer but I obviously couldn't because of my foot. I'm hoping it heals by the end of this month or else I'll pretty much have no chance of walking on the team. In the mean time, I'd like to know why it's taking so long and what I can do to help the pain.

I got it x-rayed twice and my doctor said it was a deep bruised, not fractured. I can walk, run/sprint fine but the pain is still kinda there. Sometimes it'll hurt a little when I walk and sometimes there'll be no pain at all. It hurts the most when I first wake up in the morning and start walking.
