Thank you for your query.
1. Since the nose is the most prominent part of the face, it is easily injured. It is common for the nose to bleed a little after an injury
2. If the bleeding stops in it's own or with the application of an ice pack, there is no active treatment necessary unless it bleeds again or in large amounts.
3. Tenderness and swelling (the bump) are common. Check in a mirror if there is any new deviation of the nose. Look for blood clots
in the nose and back of the throat. Feel the area of the bridge of the nose (if the pain and tenderness allows) for any crackling ('crepitus') which is a sign of nasal bone fractures
4. If you are still not sure, get your nose examined by an ENT Specialist
and get an X-ray to rule out a nasal bone fracture. Ask for a prescription of an anti-inflammatory and a pain killer.
5. Minor fractures may be left alone, most problematic nasal bone fractures are treated after three weeks after the swelling and tenderness settles down.
