Hi and thanks for the query,
Generally, the commonest cause of nose bleeding caused epistaxis is idiopathic, meaning of no known cause.
High blood pressure can cause
hypertension, but is usually accompanied by other signs and symptoms of hypertension.
Other causes of nose bleeding like
chronic rhinitis, clotting factor abnormalities and at times certain tumours are worth being excluded. It shall be interesting for you to get consulted by an
ENT specialist too, and the blood pressure well controlled.
best regards,
Luchuo, MD.
