Urticaria is a common vascular reaction disease of the skin and mucous membranes due to various causes. It is characterized by a temporary, edematous plaque, or flush, surrounded by a red halo or flush, with severe itching and, in severe cases, respiratory, digestive, and cardiovascular symptoms. The rash occurs quickly and fades quickly, leaving no trace of the rash after fading. The disease is fairly common, with literature reporting that approximately 15-25% of the population will develop urticaria at least once in their lifetime.
