Lump on Side of Nose After Break and Cut?

I slipped in the shower 3 wks ago and cracked the my nose. I cut my nose on the right side and it bled a lot, though stitches were not needed. I also broke my nose on the right side, but the plastic surgeons said t was not noticeably crooked so I ought not have it reset. This week a hard lump seems to be developing where I both cut and broke my nose. Could this be bone developing or just skin healing? It feels like it is skin not bone, as it seems to move around a bit. Will it go away?
