Cheryl, a 20-year-old Caucasian student, presents to a regional district hospital with a five-day history of odynophagia.

She has a fever but no other respiratory or systemic symptoms.

Her GP started her on oral phenoxymethylpenicillin four days ago, and two days ago, she received  IV benzylpenicillin and hydrocortisone in ED after presenting with non-resolving symptoms.

She now re-presents with severe pain, which is making even swallowing fluids difficult.
