Which sign of post-sting complication specifically warrants seeking professional medical attention according to monitoring guidelines?
Answer
Fever or chills developing later on.
While most uncomplicated Man-o'-War stings resolve after immediate first aid involving rinsing, deactivation, and heat treatment, certain symptoms indicate a potentially systemic reaction or secondary complication requiring professional intervention. The presence of systemic signs such as fever or chills suggests that the body's response has moved beyond a localized inflammatory reaction. Other serious indicators include signs of secondary infection like spreading redness, swelling, warmth, or pus at the site, or pain that severely worsens or fails to diminish after 24 to 48 hours, signaling that emergency or clinical assessment is necessary.
