Severe injuries can cause fractures
of the cartilage
complex of the nose. Since you had a rhinoplasty
earlier, I would assume that cartilage grafts were given to support the tip. I would advice you to consult a plastic surgeon as fractures, if they are present, are best reduced within the first 2 weeks or otherwise you might require another rhinoplasty! Since the swelling has not gone down even after 10 days, further investigations are needed.
