Edie, an eight-year-old girl, is seen via telehealth consultation with 24 hours of bilateral calf pain and disturbed gait, worsening despite regular paracetamol administration.

She developed URTI symptoms seven days ago, as well as a low-grade fever (37.9°C), rhinorrhoea, dry cough and sore throat, which have now almost completely resolved. Her four-year-old brother had parainfluenza virus the preceding week.
