Introduction
The appearance of a spreading red rash on the skin may be caused by conditions such as contact dermatitis, urticaria, or eczema, and treatment should be based on the specific condition. If the skin frequently comes into contact with allergenic foreign substances such as pollen or dust, resulting in symptoms like red rash and pain, topical application of compound acetic acid dexamethasone cream or oral administration of methylprednisolone tablets may be used for treatment.
A red rash gradually spreading across the skin may be caused by conditions such as contact dermatitis, urticaria, or eczema. Treatment depends on the specific condition and should be carried out accordingly. Details are as follows:
1. Contact Dermatitis
If the skin frequently comes into contact with allergenic foreign substances such as pollen or dust, inflammatory skin disease can easily develop, resulting in symptoms like red rashes and pain. Under a doctor's guidance, treatment may include topical application of clobetasol propionate cream or oral administration of medications such as methylprednisolone tablets.
2. Urticaria
Urticaria is usually triggered by prolonged exposure to cold, heat, or sunlight, and may present as hives that appear bright red or pale. Under medical supervision, treatment options include urticaria pills or ebastine tablets.
3. Eczema
This is typically an inflammatory skin condition that may be triggered by various internal or external factors. It can lead to red rashes and itching. Under a doctor’s direction, topical treatments such as desonide cream or tacrolimus ointment may be used.
In addition to the above causes, similar symptoms may also result from allergic purpura, psoriasis, tinea corporis, or other conditions. Avoid scratching with hands and maintain cleanliness of the affected area.
