How long does it take for swelling to go completely down after getting mildly hit on the side of my nose?

Today, I got hit on the side of my nose by a rubber duck that my little sister threw at me. It only hurt for a minute or two, & then I got a bump on the side of my nose. I didn't get hit hard, & I'm pretty sure my nose didn't break from a rubber duck. My nose didn't bleed or anything, but I feel mildly sore (which went away later that day). So will the bump go away, & will the swelling go down? If so, then how long would it take? & how should I treat it? Thank you in advanced!!
