What causes bloody discharge from the left nostril, and what should be done about it?
Blood in nasal discharge from the left nostril is usually caused by factors such as dry climate, intense physical exercise, trauma or irritation, rhinitis, hypertension, and others. Treatment may include general measures or medications under a doctor's guidance. Specific analyses are as follows:
1. Dry Climate
Spending prolonged periods in air-conditioned rooms can cause the mucous membrane in the left nostril to lose moisture and become dry, making it susceptible to minor friction and bleeding. Using saline solution to keep the nasal passages moist and maintaining appropriate indoor humidity can help.
2. Intense Physical Exercise
After vigorous exercise, blood vessels in the left nostril may dilate and blood flow increases, potentially leading to bloody nasal discharge. Adequate warm-up and cool-down exercises before and after physical activity are recommended to avoid sudden intense exertion.
3. Trauma or Irritation
Frequent nose picking or excessive force when cleaning the nose may damage the mucous membrane of the left nostril, resulting in blood-tinged mucus. This may be accompanied by symptoms such as pain and swelling. Medications such as erythromycin ointment, mometasone furoate nasal spray, or triamcinolone acetonide nasal spray may be used according to medical advice.
4. Rhinitis
Rhinitis is typically caused by viral or bacterial infections. Inflammation affecting the left nostril may lead to mucosal erosion and congestion, causing bloody nasal discharge. Symptoms may include nasal itching and sneezing. Medications such as Qianbai Rhinitis Tablets, Loratadine Tablets, or Tongqiao Rhinitis Tablets may be used as directed by a physician.
5. Hypertension
Hypertension may result from lack of exercise, obesity, poor diet, and other factors. Increased pressure on blood vessel walls makes small vessels in the left nostril prone to rupture and bleed, leading to the aforementioned symptoms. It may be accompanied by dizziness, headache, and blurred vision. Medications such as Benazepril Hydrochloride Tablets, Nifedipine Tablets, or Fosinopril Sodium Capsules may be prescribed under medical supervision.
It is important to correct unhealthy habits such as nose picking to help maintain overall health.
