How to treat burning and stinging skin?

Skin with a burning, fiery sensation is generally caused by factors such as contact with irritants, excessive sun exposure damaging the skin, contact dermatitis, solar dermatitis (sun allergy), or herpes zoster. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve symptoms under a doctor's guidance through general care, medication, and other treatments. Specific analyses are as follows:

1. Contact with irritants: When skin comes into contact with irritants such as capsaicin or detergents, their chemical components stimulate nerve endings, causing a burning sensation. Immediately rinse the affected area with running water for at least 15 minutes to remove residual irritants. Avoid rubbing the area with hands, and later apply a gentle moisturizing cream to soothe the skin.

2. Excessive sun exposure damaging the skin: Prolonged sun exposure damages the skin barrier, leading to epidermal cell death and resulting in a burning sensation, often accompanied by redness and peeling. Quickly move to a cool, shaded area, apply a cold compress or ice pack for 20 minutes, and apply aloe vera gel or moisturizing lotion. Avoid further sun exposure.

3. Contact dermatitis: Skin contact with allergens such as metals or cosmetics triggers an inflammatory reaction, causing burning and itching. Discontinue use of suspected allergens, and follow medical advice to use medications such as calamine lotion, hydrocortisone butyrate cream, or desonide cream. Keep the skin clean and dry.

4. Solar dermatitis: Ultraviolet radiation causes acute inflammation, resulting in red, burning skin; severe cases may develop blisters. Follow medical advice to take oral antihistamines such as cetirizine hydrochloride tablets, fexofenadine hydrochloride tablets, or loratadine capsules. Topically apply mometasone furoate cream, and strictly use high-SPF sunscreen when going outdoors.

5. Herpes zoster: Reactivation of the varicella-zoster virus causes burning pain along nerve pathways, followed by a rash. Follow medical advice to take antiviral medications such as acyclovir tablets, valacyclovir tablets, or famciclovir tablets. Use mecobalamin tablets to support nerve health, and consider nerve block procedures for significant pain relief.

In daily life, avoid known irritants and allergens, and choose mild skincare and cleansing products. Maintain a light diet, reduce intake of spicy and hot foods, and consume more fruits and vegetables rich in vitamin C. Wear loose, cotton clothing to prevent friction on damaged skin and promote healing.
