In urticaria, what term describes the individual raised, itchy bump?

Explanation:
In urticaria, each raised, itchy bump is called a wheal. This term refers to the small, well-defined area of superficial dermal edema caused by histamine release from mast cells, which produces the characteristic itchy, raised spot. Swelling is a broader description of edema that can occur in many contexts and isn’t as specific to the discrete hive lesion. A boil is an infected hair follicle and looks different, while a lesion is a generic term for any skin abnormality. So the precise name for the individual bump is a wheal.
