Thanks for writing your query.
Bleeding from nose also known as Epistaxis
, is common after injury
This occurs due to presence of network of blood vessels near the tip of the nose which can bleed easily if injured.
compress and pressure will help in stopping the nasal bleeding
You should seek medical attention immediately as nasal packing should be done with a vasoconstrictor.
Headache can occur after nose injury. You should get yourself clinically examined and get your vitals monitored.
I hope this is helpful to you.
