Skin itches and feels slightly swollen when exposed to wind.

Itching and slight swelling of the skin when exposed to wind may be caused by physiological factors, or pathological conditions such as cold urticaria or allergic dermatitis. Treatment depends on the specific condition. Detailed analysis is as follows:

1. Physiological Causes

If the skin is naturally dry, exposure to wind can remove or evaporate moisture from the skin surface, further drying it out and causing itching. Symptoms can usually be relieved by applying moisturizing lotions.

2. Pathological Causes

1) Cold Urticaria

This typically occurs after exposure to cold air, cold water, or icy objects, leading to sudden skin itching, redness, or swelling. Medications such as chronic urticaria pills or olopatadine hydrochloride tablets may be taken as directed by a physician.

2) Allergic Dermatitis

If allergens such as pollen or dust are present in the air, wind can carry these particles and irritate the skin, triggering allergic dermatitis. Symptoms include localized redness, swelling, itching, and rash. Topical treatments such as hydrocortisone butyrate cream or triamcinolone acetonide acetic acid cream may be used as prescribed by a doctor.

In addition to the above common causes, other conditions such as eczema, atopic dermatitis, or rubella may also be responsible. It is recommended to seek timely medical attention if any discomfort symptoms occur.
