What should I do for bigger nose after trauma (not broken)? (Photos)

In first days of May, for a bad personal event, I received several slaps. My nose hurt for a couple of days, and it was swollen. I didn't worry and I only went to the doctor after a month. He told me that it certainly hadn't been broken but maybe there might have been a micro-fracture but that it was impossible to tell because it could have been fixed by itself. Now my nose doesn't hurt anymore but it's still swollen and bigger. It's been almost 3 months now. What should I do? Thanks in advance.
