Hi, nasoendoscopies cost about $180 - $350 in Singapore, unsubsidized. This allows the doctor to look inside your nose at potential sources for the nosebleed, and treat it (eg. through cautery), if necessary. If cautery is required, it increases the costs of the nasoendoscopy.
The most common cause of recurrent nosebleeds in Singapore are allergic rhinitis.
Your nose has a rich supply of blood vessels that are prone to bleeding.
When your nose bleeds, sit and tilt your head forward, then press both sides of the lower third part of your nose for 10 minutes while breathing through your mouth. This should help to stop the bleeding.
