Hi, Welcome to Hcm, If I were your pediatrician, I would suggest you consult an orthopediacian or an ent surgeon, only to be very sure there is no problem to be sorted out. If at all there is a fracture, the management will vary depending on the type and extent of fracture. Mild one needs a small plaster bandage but a major one might need surgery. However, it doesn t sound like a major fracture or something. He might have had some soft tissue injury which is causing swelling and nose congestion. Hot compresses, nasal de congestant drops and steam inhalation will help till you see some specialist. Hope child gets well soon. Take care.
