What causes swelling and pain around the nose?

Generally, swelling and pain around the nose are mainly caused by weather changes, over-cleansing, skin infections, allergic reactions, rosacea, and other similar reasons. If discomfort occurs, seek medical attention promptly. Detailed analysis is as follows:

1. Weather Changes

When the outside temperature drops or humidity increases, blood vessels in the nose may react abnormally, causing minor blood vessel dilation or constriction, leading to mild edema and pain in the nasal edge tissue. Maintain a suitable indoor temperature and humidity, and avoid sudden temperature or humidity changes.

2. Over-Cleansing

Frequent use of strongly irritating cosmetics or cleaning products may damage the skin barrier around the nostrils, causing swelling and pain. It is recommended to stop using irritating cleaning products and cosmetics, and switch to gentle, non-irritating skincare products.

3. Skin Infection

Skin infections are primarily caused by bacterial or viral infections. Bacteria or viruses multiply at skin break sites, triggering an immune response that causes inflammatory cells to accumulate and release inflammatory mediators, resulting in localized redness, swelling, pain, and possibly accompanied by fever or localized pus. Patients should follow medical advice to use medications such as Ganciclovir Capsules, Foscarnet Sodium and Sodium Chloride Injection, and Amoxicillin Capsules for treatment.

4. Allergic Reaction

When allergens come into contact with the skin, an allergic reaction ensues, releasing inflammatory mediators such as histamine, causing local vasodilation and increased permeability, resulting in nasal redness and swelling, possibly accompanied by itching, rashes, and other symptoms. It is recommended to follow medical advice to use medications such as Loratadine Tablets, Ebastine Tablets, Dexamethasone Acetate Injection for treatment.

5. Rosacea (Acne Rosacea)

Rosacea may be related to multiple factors such as heredity, abnormal neurovascular regulation, and microbial infection. In rosacea, the nervous system works in conjunction to cause nasal skin inflammation, leading to the aforementioned symptoms, which may be accompanied by papules, pustules, and other symptoms. Patients can use medications such as Fusidic Acid Cream, Azelaic Acid Cream, Isotretinoin Soft Capsules under the guidance of a specialist physician.

In daily life, avoid smoking, secondhand smoke, and strong irritating odors that may irritate the nose and worsen symptoms.
