Which systemic symptom mandates immediate emergency medical service contact after a Man o' War sting?
Answer
Difficulty breathing
While localized pain is the most common outcome, certain severe systemic reactions necessitate immediate professional intervention. Symptoms indicating that the venom has spread beyond the local area and is affecting major body systems include difficulty breathing, severe muscle spasms, nausea, or vomiting. These signs suggest a generalized allergic reaction or significant systemic envenomation, requiring emergency medical services activation without delay.
