ABSTRACT
A 46-year-old woman presented to the emergency department complaining of a painful rash. She gave a history of noticing what she described as ‘red spots’ on her right leg 3 weeks earlier. Two days ago, the rash had spread to cover most of the back of her leg. The underlying skin now felt hot and pruritic and she also reported experiencing myalgia and lethargy. Her past history included a stroke 2 years earlier and subsequent epilepsy. Her regular medications included furosemide, clopidogrel, folic acid and sodium valproate. She was allergic to penicillins. She worked from home as an online retail assistant and lived with her friend. All close contacts were well. She had never smoked and drank minimal alcohol. She had no travel history.
