Question

Over the past seven days, I have felt my nose dry at night, with occasional discharge. In the morning, when I blow my nose, there is bleeding from the left nostril. The bleeding is not common, and it does not occur in both nostrils at the same time, and there is no discomfort or itching. I have never received any related examinations. What factors or diseases might cause this?

Answer

Nosebleeds are often due to diseases within the nasal cavity, and they may also be related to systemic diseases. Sometimes, tissue changes nearby can also lead to blood flowing out through the nose. Symptoms typically include nasal or sinus diseases, nasal septum deviation, unilateral bleeding, intermittent small amounts of bleeding, and environmental dryness. It is recommended to visit a regular hospital for examination immediately to determine the cause and treat it accordingly to avoid delaying the condition and missing the best treatment opportunity.
