Nose Still Swollen After Cellulitis 3 and a Half Weeks Later?

I got cellulitis on the inside of my nose that extended to the outside center of it, the top, and part of the left side about 3 and a half weeks ago. I got on antibiotics quickly and finished my full course. I had some drainage but I did not require a lancing. The infection is long gone and I haven't had pain in weeks but there is still swelling and redness. Is this normal for the nose? Can this prolonged cause swelling cause any damage or scars? Can a rhinoplasty correct it?
