Hello dear user!
I have gone through your query and understood your concerns!
Thank you for sharing them on healthcaremagic.
It is normal to have swelling of had after a trauma. It is the normal inflammatory response of the organism. Nose bleeding is very likely to have happened for the same reason. If the bleeding occurred just once, and you have not bleeding or liquid draining from your nose anymore, you have not to be so worried. Just observe if you have 
dizziness, headache, sleep feeling or liquid leaking from your nose or ears, in advance. These symptoms would be indicative for 
intracranial hypertension or 
fracture and in that case going to the hospital would be an emergency.
If you are just feeling good, you can use 
ibuprofen or 
diclofenac orally to lower the edema of the head and pain if you have.
I hope this answer was helpful to you!
