What causes a crusty stickey feeling just inside the nose nearest upper lip?

Several factors can contribute to a crusty, sticky feeling just inside the nose, near the upper lip:

1. Dried Mucus: When mucus, produced by the nasal passages, dries up, it can create a crusty, sticky sensation. This commonly occurs during dry weather, low humidity, or dehydration.

2. Allergies: Allergic reactions can cause inflammation and increased mucus production in the nasal passages. When this mucus dries, it can lead to crusting and stickiness. Common allergens include pollen, dust mites, pet dander, and certain foods.

3. Sinusitis: Sinusitis, an inflammation of the sinuses, can cause nasal congestion and thick, sticky mucus. This can lead to crustiness and a feeling of stickiness inside the nose.

4. Nasal Polyps: Nasal polyps are non-cancerous growths that can form in the nasal passages. They can obstruct airflow and cause a build-up of mucus, resulting in crusting and stickiness.

5. Deviated Septum: A deviated septum is a condition where the nasal septum (the cartilage and bone that divides the nostrils) is off-center. This can cause nasal obstruction, leading to crusting and stickiness.

6. Certain Medications: Some medications, such as decongestants and nasal sprays, can cause dryness and crusting in the nasal passages.

7. Underlying Health Conditions: In rare cases, a crusty, sticky feeling in the nose can be a symptom of an underlying health condition, such as immune deficiencies or certain autoimmune diseases.

If you experience persistent crusting and stickiness inside your nose, it's advisable to consult a healthcare professional for proper evaluation and treatment.
