What happens when you have the blood vessels in your nose cauterized??
ive had this done...they use what looks like a giant matchstick with silver nitrate on the tip and run on the inside of your nostrils..it stings a bit afterwards but it is excellent i havnt had a nose bleed once since in 15 years!!!
you will stop bleeding.
You shouldn't get anymore spontaneous nose bleeds.
The doctor will burn the blood vessels, thereby sealing them.
nothing, it will help you if you have epistaxis, it can stop bleeding
