| A Weal is another (non-medical) term
used to refer to similar types of skin
lesion as "hives", "nettle
rash" , "urticaria" (the medical
term), and "wheals".
Genmerally, weals 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, weals can constitute
a medical emergency if the lips, eyes, or tongue are affected because considerable
swelling can occur.
