Dr. Wang Bing
Persistent nosebleeds that cannot be stopped may be caused by ruptured blood vessels in the nasal cavity, or may be related to nasal cysts or inflammation. If the nose has suffered trauma, it may lead to uncontrollable bleeding. Frequently picking the nose with hands can cause damage to the nasal mucosa and result in nosebleeds. If nasal bleeding cannot be controlled, it is important to seek prompt medical attention and receive treatment under a doctor's guidance.
