A Calf Bull Butt Headed Me And Knocked Me To

a calf bull butt headed me and knocked me to the ground on my hip. It is swollen the size of half a small football and has pain. I took an alieve and put a pack of frozen peas on it. The next day it still is the same. Will swelling go down? How do I know if its ok? If it were broke I probably wouldn't be able to walk on it I am assuming.
