Hello and welcome to Health Care Magic,
Presence of blood in nostrils indicates injury
to the nasal mucosaand subsequent bleeding.
Removal of the dried blood makes the injured surface raw and thus repeated bleeding and crusting.
In order to halt this process use a wet pack after removal of the dried blood.
Packing can be made by simply soaking the cotton in bland emollient
This will heal the raw surface and hence halt the bleeding.
It is unlikely that a pituitary adenoma
is associated with the nose bleed.
Thanks and take care
