Be seen today
Get urgent same-day medical assessment if the inside of the nose becomes increasingly blocked, painful, or swollen, especially if you can see a soft red or purple bulge.
These may be signs of a septal haematoma.
Prompt assessment is also appropriate if the nose looks crooked, breathing through it is difficult, bleeding keeps returning, or the injury involved a strong impact.
Treatment to realign the nose may be time-sensitive.

Does any of this apply?
Book an appointment
Routine follow-up is reasonable if swelling is not improving, pain continues beyond the expected recovery period, or you notice lasting changes in breathing, smell, or appearance after the nose has healed.
Every sign above is quoted from the sofidex article on Nose fracture. If you are not sure, err upward — it is always reasonable to be checked.
