Replying to Foot Injury

So yesterday in a football game i got hit and landed on my feet, yet all of the pressure was taken up by my heel. i went to the trainer today and was told i bruised my heel bone. it hurts to put pressure on it, and i still play football with a special heel insert that doesnt seem to do much. so does anybody have suggestions to help it heal faster or make it less painful? because it is not bad enough that i cant play, and i am looking at 2-3 weeks for it to heal.
