What could be the reason for a persistently non-healing sore inside the nose?

Under normal circumstances, persistent non-healing sores inside the nose may be caused by dry environments, malnutrition, sinusitis, nasal vestibulitis, or nasal vestibular eczema. Patients should promptly visit a reputable medical facility to identify the underlying cause and receive appropriate treatment. Specific analyses are as follows:

1. Dry Environment

When the environment is excessively dry, moisture in the nasal cavity evaporates rapidly, causing the nasal mucosa to become dry and fragile, making it prone to damage. If left untreated, this can lead to the aforementioned issues. It is recommended to maintain indoor humidity, for example by using a humidifier, and to drink plenty of water to ensure adequate hydration.

2. Malnutrition

Long-term malnutrition, especially deficiencies in nutrients such as vitamin A and vitamin B2, can impair the normal repair function of the nasal mucosa, resulting in delayed healing of damaged areas and leading to the symptoms described above. It is advisable to adjust the diet promptly by increasing intake of foods rich in vitamin A and vitamin B2, such as carrots, spinach, and animal liver.

3. Sinusitis

Sinusitis is an inflammatory condition affecting the mucous membranes of the sinuses. Due to inflammatory irritation, the nasal mucosa becomes congested and swollen, making it susceptible to injury and slow healing. This condition may also present with symptoms such as purulent nasal discharge, nasal congestion, headache, and fever. Under medical guidance, patients may use medications such as Biyan Tongqiao Granules, Cefixime Capsules, or Tongqiao Biyan Tablets for treatment.

4. Nasal Vestibulitis

Nasal vestibulitis is a diffuse inflammation of the skin in the nasal vestibule. It may result from irritation due to nasal secretions associated with acute or chronic rhinitis, sinusitis, or allergic rhinitis, prolonged exposure to harmful dust, or bacterial infection secondary to habitual nose-picking. These factors may contribute to the aforementioned symptoms. As directed by a physician, topical treatments such as Metronidazole Gel, Clindamycin Ointment, or Mupirocin (Bactroban) Ointment may be used.

5. Nasal Vestibular Eczema

Nasal vestibular eczema is a skin inflammatory reaction that may be triggered by various factors including allergies or infections. It causes erosion and exudation of the skin in the anterior nasal area, often accompanied by itching and a burning sensation. Without timely treatment, the condition may persist as described. Under medical supervision, patients may use medications such as Hydrocortisone Butyrate Cream, Loratadine Tablets, or Cetirizine Hydrochloride Tablets.

In daily life, it is recommended to maintain a positive mindset, avoid spicy, stimulating, and greasy foods, get sufficient rest, and develop healthy lifestyle habits.
