A severe allergic reaction, often referred to as anaphylaxis, involves the immune system's extreme response to a triggering allergen. The signs of a severe allergic reaction typically include symptoms like urticaria (hives), bronchospasm (tightening of the airways), and swelling of the lips and other areas, which indicate that the body is experiencing a significant and potentially life-threatening response.

Headache, while it can occur due to various conditions, does not specifically indicate an allergy or allergic reaction. It is more often related to other causes such as tension, dehydration, or sinus issues, rather than being a direct, recognized symptom of severe allergic reactions. Thus, identifying these symptoms allows EMTs and responders to discern when a condition may not be life-threatening and manage accordingly. Understanding the distinction is crucial for effective diagnosis and treatment in emergency settings.
