If Urticaria causes inflammation or discoloration of the skin that lasts more than 24 hours, then an underlying non-allergy related medical problem may be the cause. When swelling of the deep skin tissue is associated with hives, it is called angioedema. Angioedema occurs in about half of people who have chronic Urticaria. Angiodema or swollen soft tissue that is not associated with hives is not usually itchy. It can involve the lips, eyes, hand, foot, throat, genitals, or rarely internal swelling causing abdominal pain. Throat or tongue swelling can be a life-threatening emergency as it can cut off air supply.
