hello and welcome to HCM,
It is understandable that you find the blood and the pack coming out of your nose scary but rest assured it is normal after any nasal surgery
Our nose is a very rich organ as far as blood circulation is concerned. Thus any problem in the body the nose has a tendency to bleed. The cauterization
will stop the bleed but you must understand that the stoppage is only for the recent bleed. You need to be investigated further for recurrent nose bleeds to prevent further attack and get a permanent cure.
I would wait for the cauterization area to heal and advice you to take an endoscopic examination of the nose and paranasal sinuses
and also ask for a CT for further evaluation.
Meanwhile do not forcibly blow or try to remove the pack. If it comes out and there is no massive bleed then you have nothing to worry about. If there is massive bleed then you need to visit the doctor immediately
take care and recover soon
