Nose Cartilage Fracture Help? (photo)

Seven months ago when I was playing basketball, a man headbutted me in my septum (full speed). I heard a crack and it hurt a lot, I was pouring out blood (first bloody nose ever), I couldn't see, and my eyes were watering. I went to a ENT doctor and got an x-ray and he said that my nose was just barely deviated. I've been occasionally alternating with heat and ice on it and it's been getting a little bit smaller. Will it fully recover without surgery? What can I do to help it? Im 16.5 years old
