Urticaria and angioedema: Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))

The characteristic features of urticaria are distinct, raised, evanescent (temporary) dermal wheals surrounded by an erythematous flare. These lesions may vary in size. In cholinergic urticaria, the wheals may be tiny and blanched, surrounded by erythematous flares.

Angioedema characteristically produces nonpitted swelling of deep subcutaneous tissue, usually on the eyelids, lips, genitalia, and mucous membranes. These swellings don’t usually itch but may burn and tingle.

anaphylaxis: Signs and symptoms
(Handbook of Diseases)

An anaphylactic reaction produces sudden physical distress within seconds or minutes after exposure to an allergen. A delayed or persistent reaction may occur up to 24 hours later. The severity of the reaction is inversely related to the interval between exposure to the allergen and the onset of symptoms. Usually, the first signs and symptoms include a feeling of impending doom or fright, weakness, sweating, sneezing, shortness of breath, nasal pruritus, urticaria, and angioedema, followed rapidly by symptoms in one or more target organs.

Systemic effects

Cardiovascular signs include hypotension, shock, and sometimes cardiac arrhythmias, which, if untreated, may precipitate circulatory collapse.

Respiratory signs and symptoms can occur at any level in the respiratory tract and commonly include nasal mucosal edema, profuse watery rhinorrhea, itching, nasal congestion, and sudden sneezing attacks. Edema of the upper respiratory tract, resulting in hypopharyngeal and laryngeal obstruction (hoarseness, stridor, and dyspnea), is an early sign of acute respiratory failure, which can be fatal.

GI and genitourinary signs and symptoms include severe stomach cramps, nausea, diarrhea, and urinary urgency and incontinence.
