Can you re-deviate your septum by hitting yourself in the face?

I had a septoplasty and turbinate reduction at the end of December 2016. 4 weeks ago I was fixing the couch cushion and slipped and hit myself full force in the nose. Since then, I have had a lot of PND and a constant cough. I'm really worried I could have potentially messed up something but not sure if I could be overreacting. I've been taking allergy medicine for my slight allergy I have but no help.
