What causes redness, swelling, and pain upon touch at the tip of the nose?

Under normal circumstances, redness and swelling of the nasal tip accompanied by pain upon touch may be caused by poor lifestyle habits, skin irritation, nasal vestibulitis, folliculitis, or rosacea. If abnormalities occur, timely medical consultation is recommended. The specific analysis is as follows:

1. Poor Lifestyle Habits

Long-term sleep deprivation, irregular作息, and diets high in spicy or greasy foods can lead to hormonal imbalances and disrupt normal skin metabolism, potentially causing redness, swelling, and pain in the nasal tip. It is advised to regulate daily routines, ensure adequate sleep, maintain a light diet rich in vegetables and fruits, and keep the skin clean.

2. Skin Irritation

The skin on the nasal tip is relatively sensitive and prone to external stimuli or allergens, such as certain ingredients in cosmetics or skincare products, or air pollutants, which may trigger inflammatory reactions like redness, swelling, and pain. Avoid re-exposure to allergens, maintain skin cleanliness, use gentle skincare products, and if necessary, take antihistamines under medical guidance, such as cetirizine tablets, loratadine tablets, or ebastine tablets.

3. Nasal Vestibulitis

In winter or dry environments, the skin of the nasal vestibule may become dry and cracked, making it susceptible to bacterial infection and resulting in inflammation. Symptoms include redness, swelling, and pain at the nasal tip, along with pain, itching, and sometimes bleeding inside the nostrils. Applying moisturizing creams to the face and keeping the nasal cavity hydrated can help; avoid nose picking.

4. Folliculitis

Folliculitis is an inflammatory condition of the hair follicles. When follicles become infected with bacteria, they may exhibit redness, swelling, and pain. The nasal tip contains abundant hair follicles and is thus vulnerable to infection. Affected areas may develop red papules that are painful to touch, and in severe cases, may progress to pus formation or ulceration. Treatment should be guided by a physician using medications such as erythromycin ointment, clindamycin phosphate gel, or mupirocin ointment.

5. Rosacea

The pathogenesis may involve genetic factors, immune system abnormalities, and microbial infections. It may affect blood vessels and sebaceous glands in the facial area, leading to symptoms such as facial redness and pain on the nose. Other manifestations may include flushing, oily skin, and pustules. Follow medical advice for treatment with antimicrobial agents such as minocycline capsules or ivermectin cream, and topical treatments like sulfur lotion to control inflammation and infection.

In daily life, if an allergic reaction is suspected, discontinue contact with or consumption of potential allergens immediately. Additionally, maintain clean and dry skin to reduce the risk of developing skin conditions.
