I Was Playing Basketball, Took A Charge And Fell Directly

I was playing basketball, took a charge and fell directly on my right hip. It hurt but I got up thinking it was fine. I tried to run and I couldn't without a lot of pain. It's about and hour and a half after the game now, and it still hurts nearly as bad as it did earlier. It feels very stiff and hurts immensely in whatever position I'm in. I can walk on it, with a bit of a limp, but if I put to much pressure there is a very sharp pain that shoots from my outer hip area to the inside of my leg. It looks a bit swollen right on the outside of my leg in front of my butt and hurts a lot to put pressure on it. I can't move my leg backwards or move my knee up and rotate it outward. I have another game tomorrow and I'm not sure if this is serious so please help!
