How strong is a nose with grafts and what to do after being hit? (Photos)

I had a revision rhinoplasty a decade ago which included extensive grafting from my septum to rebuild my nose. Large spreader grafts were sown in both sides, a columella strut graft and tip grafts were added too. 2 weeks ago someone bumped into my nose quite hard. It hurt, a numb sensation. My nose did not bleed and no significant external swelling was apparent. My breathing seemed off though and my nose skin looked a little sore. How likely is damage and what steps to take next?
