My body is red and itchy.

This is acute urticaria. This is an allergic reaction. The onset of this disease is more urgent. Patients often suddenly feel itchy skin, and soon red air masses of different sizes appear in the itchy area, which are round, oval or irregular, and can be distributed in isolation or expanded into sheets. The skin surface is uneven and has an orange peel-like appearance. After several hours, the edema was relieved, and the wind mass became erythema, which gradually disappeared without leaving any trace. The duration of skin lesions is generally less than 24 hours, but new skin lesions can appear one after another.
