Okay so I was basketball and I was going for a crossover, and somebody tripped me, and then I fell down, but I think I twisted it pretty badly. I couldn't walk, nor get up. Is my ankle broken or sprained? Its not purple or anything . . . and I have been limping on the court, (okay, so the other thing wasn't exactly a lie), but I was limping . . . is it broken? Or sprained? Please help me . . .
