What causes dryness and itching in the nose?

Dryness and itching in the nose are generally caused by environmental irritation, allergic rhinitis, sinusitis, nasal vestibulitis, atrophic rhinitis, or other reasons. It is recommended that patients visit a qualified hospital for relevant examinations and receive targeted treatment based on the underlying cause. Specific analyses are as follows:

1. Environmental Irritation

Prolonged exposure to dry environments, such as air-conditioned rooms or over-heated indoor spaces during winter, may cause the nasal mucosa to lose moisture, leading to dryness and itching. Patients can open windows regularly for ventilation and drink adequate amounts of water to replenish bodily fluids.

2. Allergic Rhinitis

Allergic rhinitis is a common nasal condition. When allergens enter the nasal cavity, they trigger an immune response, resulting in swelling of the nasal mucosa, increased secretions, and symptoms such as dryness, itching, sneezing, and nasal congestion. Under medical guidance, patients may take medications such as loratadine tablets, cetirizine hydrochloride tablets, or ebastine tablets, which have anti-allergic effects.

3. Sinusitis

Sinusitis refers to inflammation of the sinuses, usually caused by infection. Excessive nasal secretions in patients with sinusitis may irritate the nasal mucosa, causing dryness and itching. In addition, sinusitis may also lead to other symptoms such as nasal congestion, headache, and facial pain. Under medical guidance, patients may use medications such as Biyuantongqiao Granules, cefixime capsules, or Tongqiao Biyan Tablets.

4. Nasal Vestibulitis

Nasal vestibulitis is inflammation of the skin in the nasal vestibule, often triggered by nasal secretions. These secretions—especially purulent ones—can frequently irritate the skin of the nasal vestibule, causing dryness, itching, pain, and other discomforts. Under medical guidance, patients may take medications such as cefaclor granules, amoxicillin capsules, or erythromycin ointment, which have anti-inflammatory effects.

5. Atrophic Rhinitis

This condition may be caused by hormonal changes and typically presents with symptoms such as dryness and itching in the nasal cavity and throat, as well as nosebleeds. Under medical guidance, patients may use medications such as mometasone furoate nasal spray, fluticasone propionate nasal spray, or oxymetazoline hydrochloride nasal spray.

In daily life, maintain clean and hygienic skin, and avoid picking the nose with dirty hands to prevent skin damage and potential adverse effects on health.
