I Was Playing Basketball, And I Don't Remember Getting Kicked

I was playing basketball, and I don't remember getting kicked in the shin, but after 2-3 games, I couldn't run without limping. And i checked my right leg and I had what felt like hard swelling on the inner side of my shin. I iced it and the swelling went down quit a bit, but there is still swelling and a blueish bruise. I am afraid that I have a stress fracture or shin splints. I am going to Disneyland tomorrow and Sunday, will walking on it all day damage it?
