Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned by the soft tissue nasal injury.
Soft tissue swelling of the nose indicates hematoma, fractured nasal bones and/or cartilages, or both. Intranasal inspection with a nasal speculum may reveal a deviated septum, a septal hematoma, or cerebrospinal fluid leakage. If a septal hematoma is suspected, it might need aspiration with an 18- or 20-gauge needle; an incision and drainage procedure might be required if the hematoma is confirmed. If the hematoma is missed and untreated, chondromalacia of the nasal cartilages may develop and become what is known as a saddle-nose deformity.
You must consult ENT specialist if nasal injury is taking too long to heal for definitive diagnosis as the same is not possible online.
Hope this helps. Take care.
Note: This post is not to emphasise final diagnosis as the same cannot be made online and is aimed just to provide medical information and no treatment suggested above be taken without face to face consultation with health care professional.
