How long does it take for temporary dorsal hump from trauma to go down?

I hit my nose hard on a pillar 3 weeks. The pain was quite bad and I went home immediately and slept it off. The next morning it was swollen and red. I noticed there was a small bump on my nose - which is still there I have pressure in my nose - would this be the result of lingering swelling/inflammation? When I press on the bridge of the nose and pull to one side, the bump on the bridge goes down. Its given me some hope but I am slightly sceptical that this is just what happens to any nose.
