Urticaria consists of itchy pink or white raised areas of skin resembling a nettle rash, known as welts or hives. These are often round or ring-shaped and can appear anywhere on the skin. Children with urticaria can sometimes also develop swelling of the lips, face, hands and feet or around the eyes. Because of the itching and appearance, urticaria can be very distressing, but rarely leads to more severe allergic symptoms.
The rash usually disappears within a few hours but can last up to a few days. Urticaria is described as acute if it lasts less than six weeks and chronic if it lasts over 6 weeks. In chronic urticaria, we thoroughly investigate whether the urticaria is triggered by environmental factors or if there is an underlying cause to this and recommend appropriate treatments to control the symptoms.
