Since there is a lack of picture of your nose, therefore determining the kind of damage that took place, is difficult.
So assuming that you have a minor fracture which didn't make your nose crooked or misshaped, then you may not require professional medical treatment. Your doctor however, may recommend simple self-care measures, such as using ice on the area and taking over-the-counter pain medications.
If there are displacements of and breaks in bones & cartilages, then the doctor may be able to realign your nose manually, or you may require a surgery.
if this has gone untreated for more than 2 weeks, or if your damage is way too severe, then reconstructive surgery may be needed.
And only your doctor, through some trials, will be able to decide which treatment fits you the best - Cosmetic Surgery doctors in Mumbai.
