Bump on side of nose after Septoplasty? Cartilage?

I had septoplasty around 4 weeks ago to correct a deviated septum. As the swelling has gone down i've noticed a slight bump only on my left side of the nose, which was the deviated side. I've inspected the inside of my nostril and the top seems more hard than the other side. Is this cartilage? Will it go down on its own or would it need to be fixed?
