What should I do if a runny nose causes sores under the nose?

In general, nasal discharge causing ulceration below the nose may be due to external factors, allergic reactions, rhinitis, bacterial infection, or viral infection. The condition can be managed through wound cleaning and anti-inflammatory treatment. First, clean the wound thoroughly by removing mucopurulent secretions and crusts, then apply an anti-inflammatory ointment to the affected area as directed by a physician.

1. External Factors

Other factors may contribute to nasal discharge and eczema with ulceration below the nose, such as changes in weather, air pollution, or exposure to irritating chemicals. It is recommended that patients rinse their nasal cavities with warm physiological saline to maintain cleanliness of the nasal mucosa.

2. Allergic Reaction

The condition may result from an allergic reaction triggered by allergens such as pollen or dust mites. These substances can irritate the nasal mucosa, leading to runny nose, and may also cause skin sensitivity and ulceration below the nose. Patients are advised to take antihistamines such as loratadine or cetirizine hydrochloride under medical guidance.

3. Rhinitis

The symptoms may be related to rhinitis, which is inflammation of the nasal mucosa. Common symptoms include nasal congestion, rhinorrhea, and eczema or ulceration of the skin around the nose. Patients are advised to take medications such as vitamin C tablets or amoxicillin capsules as prescribed by a doctor.

4. Bacterial Infection

If the ulcerated area becomes red, swollen, produces pus, or is accompanied by fever, it may indicate a bacterial infection. Patients should use topical antibiotics such as erythromycin ointment or tetracycline ointment as directed by a physician.

5. Viral Infection

Certain viral infections, such as influenza virus or rhinovirus, may also cause nasal discharge and ulceration below the nose. Patients are advised to take antiviral medications such as acyclovir tablets or sodium penicillin under medical supervision.

In addition, patients should promptly correct unhealthy habits such as habitual nose-blowing or aggressive wiping of the nose.
