Re-injured knee. how long to recover?!

keep this short. i was skiing last sunday, twisted my knee (foot to outside) pain appeared on inside front beside patella. was recovering, had football camp next sunday, re-injured by bending knee to outside (against normal movement) plus a hard smash to inside of patella, now worse. what could this be and how long should i wait? (yes, im going to a doctor asap. free healthcare ;))
