Which symptom is NOT associated with anaphylaxis?

Anaphylaxis is a severe allergic reaction that can manifest with a variety of symptoms, typically affecting multiple systems within the body. Among these symptoms, swelling in the face and/or tongue, respiratory distress, and the presence of itching and hives are classic indicators of anaphylactic shock. Swelling can lead to airway obstruction, respiratory difficulties arise from bronchospasm and throat swelling, and skin reactions like hives often occur as part of the body's response to allergens.

In contrast, intense fatigue is not a hallmark symptom of anaphylaxis. While individuals may feel fatigued after an allergic reaction, especially as they recover, intense fatigue is more common in other conditions and is not a defining feature of anaphylaxis. It does not indicate an immediate life-threatening response like the other symptoms do. Therefore, recognizing the correct symptoms associated with anaphylaxis is crucial for timely intervention and treatment.
