Can "stuffiness" after minor nasal trauma be fixed?

My nose suffered from mild trauma three weeks ago. It didn't bleed nor hurt whatsoever, did feel weird after, and encountered a small clicking sound when I washed my face (my father who is a doctor said it wasn't broken though) and there might be a slight change in the appearance (not sure, my family says there isn't). The problem is that it feels very stuffy from time to time, almost as if it is going to explode, (mostly on middle area). Any ideas?
