Is it possible for a deviated septum to go away on its own?

I got injured and for the past few months I've had a blocked right nostril, but it seems to be gradually getting better every few months. Doctor said my cartilage was bent/deformed, but not broken. From every study I read it says "cartilage is flexible, has memory, and goes back to its original position over time"....please tell me is there any hope my septum will get straight again or do I have to undergo painful surgery? (this annoying partial right nostril blockage every day is killing me)
