Patients with mild urticaria may recover spontaneously after the possible causative triggers are removed. Most patients with urticaria generally do not recover spontaneously without standardized treatment. Urticaria, commonly known as rubella, is a skin allergic disease that is a limited edema-like plaque of the skin caused by dilatation and increased permeability of small blood vessels in the skin mucosa. It usually subsides within 2 to 24 hours, but in cases where the allergen is unknown, it can lead to repeated exposure to the allergen thus prolonging the course of the disease for days to months or even longer. With proper and standardized treatment, urticaria can be cured by gradually relieving the allergic symptoms. However, the recurrence rate of urticaria is high, so we must pay attention to avoid allergens that may trigger urticaria in our daily life. Urticaria patients are advised to seek medical treatment in time and standardize the treatment under the guidance of professional doctors.
