Suggest Treatment For Pain And Swelling In Knee After An Injury

(i'm a girl, 21) i ran extremely hard into a wall (over 2weeks ago now), taking pract the full inpact onto my left knee, my knee instantly swelled up, i did the whole ice and rest thing but it just keeps re-swelling and is painful to bend and walk on, its still bruised and sore. i went to the GP about 6days after to get it checked but he just said take pain killers and see if it goes down. people keep mentioning i could have fractured my knee but sources say i wouldn't be able to bend or walk on it at all. what should i do?
