A severe allergic reaction, also known as an anaphylactic reaction, is characterized by specific symptoms that can signal a life-threatening situation. The presence of hives, swelling (especially of the face, lips, or throat), and difficulty breathing are all critical indicators of a severe reaction. Hives refer to raised, red welts on the skin and are a common manifestation of an allergic response, while swelling can impede airflow and lead to respiratory distress. Difficulty breathing may result from the swelling of the airways, a severe constriction of the bronchial passages, or an overwhelming release of histamines that results in bronchospasm.

In contrast, symptoms such as itching and redness, chronic sinus congestion, and minor skin irritation, while they may indicate an allergic response, do not typically signify the severity associated with anaphylaxis. These symptoms are usually milder and more manageable, not requiring immediate emergency intervention. Therefore, recognizing the combination of hives, swelling, and breathing difficulties is essential for identifying and responding appropriately to a severe allergic reaction.
