| Urticaria is the medical
name for the type of skin
lesion also known as "wheals".
Urticaria is known by many names including "hives"
which is the most common name, "wheals", "weals", and "nettle rash" which
is
a type of hive or wheal.
Generally, urticaria are rounded or flat-topped
elevated lesions caused by flares of swollen skin containing an
accumulation
of
fluid.
(The medical
term for "swollen with an excessive accumulation of fluid" is "edematous" -
though this word is not used in all texts).
They usually occur as a result of an allergic reaction and the
release of histamine.
Although usually transitory, they can constitute
a medical emergency if the lips, eyes, or tongue are affected because considerable
swelling can occur.
