Hives do not leave marks; they come and go and leave no trace when they subside. Urticaria manifests itself in the form of erythematous, windswept rashes, which will definitely subside within 24 hours, but urticaria is prone to recurring. It is recommended to give timely treatment, mainly given antihistamines oral treatment. If there is an urticaria-like rash that leaves a mark after it subsides, it may be considered urticarial vasculitis or urticaria-type drug rash. Both of these diseases need to be treated with glucocorticosteroids, and the marks will gradually fade away after treatment and will not remain permanently. However, the severity of these two diseases is more serious than that of urticaria, so it is best to follow the doctor’s instructions and use medication regularly.
