Urticaria and angio-oedema
Urticaria is also known as hives or nettle
rash. It is an allergic skin disorder characterised by severely
itching lumps or rashes. Those rashes may occur anywhere on the
body, occasionally causing a burning and chafing feeling. It has
many causes, ranging from foodstuffs to detergents, from skin care
products to even sunshine. Sun allergy is a form of urticaria, for
example.
Angio-oedema is a special type of urticaria or nettle rash, an allergic skin disorder characterised by itching lumps or rashes. The itching is considerably less severe, but the lumps accompanying angio-oedema are much bigger than those associated with urticaria. Angio-oedema often manifests itself on the eyelids, lips and mucous membranes.
