Answer

Typical lesions described by patients are edematous pink or red wheals of variable size and shape that are pruritic. [31] The lesions are often described as welts or hives, including pressure-induced hives, which can occur with elastic or tight clothing, as shown in the images below. [32] Patients may report a painful or burning sensation; such lesions are often associated with angioedema. [33] Pruritus of nonlesional skin may also occur.
