Patient's question:
Starting seven days ago, when going to sleep at night, my nose has been dry, with occasional mucus. When I wake up in the morning and blow my nose, there is blood. Usually, it's the left nostril that has blood, not both nostrils at the same time. It's not blocked or itchy. I haven't gone for a check-up yet. What could be the cause or factor?Doctor's answer:
Cause: Most often caused by nasal cavity lesions, but can also be caused by systemic diseases. Occasionally, it may be due to nearby nasal lesions initially leaking through the nasal cavity.Symptoms: Mostly include nasal and sinus diseases, deviation of the nasal septum, unilateral bleeding, intermittent small amounts of bleeding, and dry external environment.
Advice: It is recommended to seek timely examination at a regular hospital to identify the cause. Targeted treatment should be administered to avoid delaying the condition and missing the optimal treatment window.
