Silver nitrate was used for the skin cauterisation; now is avoided.

Some pain and discomfort is to be expected after any surgical procedure, and nasal cauterisation can be uncomfortable. Painkillers taken regularly for a few days should keep the pain in control

No.

Cauterisation heats a metal tip using electricity and it is the heat transfer from this tip to the tissue that causes an effect.

Electrosurgery actually passes RF electricity through the tissue.

Yes. Cauterisation is when tissue is burnt by an electric current to remove or close part of it from a metal probe. This will then blood from small vessels to become extremely hot and therefore to control the bleeding.
