Is it broken?

Two days ago, I was helping my son get dressed for school. I was leaning over him, holding his jeans for him to step into (he can dress himself, he’s just not a morning person) when he jumped, head-butting me squarely in the nose.

Ow.

Now, there was no bleeding, no obvious bruising (and I’m a bruiser) or external swelling , but I’m experiencing sinus congestion, and the bridge of my nose, right between my eyes and eyebrows, is terribly sore.

Is this something that requires attention of some sort? Or will it just take a while to heal?
