Differential Diagnoses: 1. Anaphylaxis (high probability) 2. Angioedema (less likely without specific trigger) 3. Acute Asthma Exacerbation (less likely given allergy history) 4. Panic Attack (less likely given physical symptoms) Required Actions: - Dispatch of ground EMS with ALS capabilities. - Preparation for potential airway management (intubation). - Administration of epinephrine if available. - Oxygen administration. - Rapid transport to hospital.
