Urticaria, also known as hives, is an outbreak of swollen, pale red bumps or plaques (wheals) on the skin that appear suddenly -- either as a result of the body's reaction to certain allergens, or for unknown reasons. Hives usually cause itching, but may also burn or sting.
Chronic hives are defined as hives that last more than six weeks or hives that go away, but recur frequently. In most cases of chronic hives, a cause is never clearly identified. In some cases, chronic hives may be related to an underlying autoimmune disorder, such as thyroid disease or lupus.While the underlying cause of chronic hives is usually not identified, treatment can help with symptoms.ives and angioedema also occasionally occur in response to blood transfusions, immune system disorders such as lupus, some types of cancer such as lymphoma, certain thyroid conditions, and infections with bacteria or viruses such as hepatitis, HIV, cytomegalovirus or Epstein-Barr virus.
