Red bumps on the body are itchy and are considered allergies, possibly hives or eczema. Hives and eczema are clinically different but similar in treatment. Urticaria is a red or skin-colored, wind-like damage on the trunk of the extremities, slightly elevated on the skin, rising and falling, irregular in shape, varying in size, and can also fall off on its own within 24 hours without treatment. Eczema is usually a red papule of rice-like to corn-like size seen on the trunk of the extremities, with visible scratch marks and oozing eruptions. Treatment for eczema and urticaria is mainly based on antihistamines and can be considered with levocetirizine, loratadine, epalmatine, etc. In severe cases, two antihistamines can be taken orally at the same time in a day, either loratadine in the morning or levocetirizine in the evening. You can also add compound glycopyrrolate two capsules once, three times a day. Topical medications can be considered to apply glycopyrrolate lotion or corticosteroid creams, such as Denide cream, Elocon cream, etc.
