Clinical manifestations

The basic damage is wheal on the skin. Often there is skin itching first, and then there is wheal, which is bright red or pale and skin-colored, and a few patients have edematous erythema. Wind masses vary in size and shape, and the onset time is uncertain. The wind mass gradually spread and merged into pieces. Due to dermal papilla edema, it can be seen that the epidermal hair follicle mouth is sunken downwards. The wind mass lasts for several minutes to several hours, and a few of them can be extended to disappear after a few days, leaving no trace. Rashes occur repeatedly in batches, especially in the evening. Wind masses are often widespread or limited. Sometimes it is complicated with vascular edema, and occasionally bullae are formed on the surface of the wind mass.
