Crooked painful nose after rhinoplasty: Is it Just Swelling?

I'm three weeks post rhinoplasty and my nose is twisted. Pre op I had a bulbous ,droopy tip and a hump. I asked for my nose to be refined, the hump and tip reduced. My tip looks too big and is slanting to the left. How long before I know whether it's just swelling or the cartilage has set out of line. It's still very sensitive, particularly the tip.
