I have gone through your description. Blunt injuries on nose could lead to fracture
of nasal bones. They can cause pain, swelling and nasal bleeding
. The swelling subsides in a week and then proper assessment can be done. Also, X ray of the nasal bones have to be taken to see the nasal bones. Sometimes, hematoma can develop in the nasal septum
during such conditions.
Hence it is better to visit an ENT specialist
for a thorough examination.
