Hello dear
I understand your concern
Trauma, nose pricking,
allergic rhinitis, deviated
nasal septum are most common cause of nose bleeding.
Other less common causes are:
Thrombocytopenia,
hypertension, live disease, side effect of blood thinner drugs, abnormal blood vessels or polyp/cancers in the nose.
I would suggest to
consult ENT specialist and undergo nose examination, blood pressure measurement, CBC, ESR, LFT to rule out cause.
Meanwhile you can take following advises to stop bleeding:
1. Sit down, pinch your nose just above nostrils for 15-20 minutes
2. Relive after 15 minutes and again after 5 minutes pinch it again till the bleeding stops
3. Take breath through mouth.
4. Do not blow through nose
5. Apply cold pack on your nose: it constricts your nose blood vessels
6. Do not lie down flat and avoid strenuous activity.
7. If note resolved you should take vitamin K injection.
8. Lastly investigation like X-RAY head, CT scan should be one if bleeding persists
Hope this may help you
Best regards
Dr. Sagar
