| A Hive is the common (non-medical) name
for the type of skin
lesion also known as a "wheal".
Hives are known by many names including "wheals", "weals",
"nettle rash" which is a type of hive or wheal, and "urticaria" - which
is the medical name.
Generally, hives are rounded or flat-topped elevated lesions
caused by broad flares of swollen skin containing an excessive 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.
