First up, is 26-year-old David whose rotting, bleeding, puss-filled armpit has left him unable to lift up his arm without tearing the skin. The problem is diagnosed as Hidradenitis Suppurativa, a condition in which the sweat glands are blocked up, infected and develop into boils. Dr Christian sends a swab sample for analysis to reveal the bacteria infecting David, in order to prescribe the appropriate antibiotics. In the meantime, David is told to take steroids to help contain the symptoms and has been referred to a surgeon to see what can be done about the damaged skin. The EB Bus heads out to Cambridge, and first to see Dr Pixie is Lucy who has a problem growing hair, whilst Dr Christian sees a 3-year-old that has problems staying on her feet. Meanwhile, Dr Priya meets a footballer whose passing is not being helped by a curling toe.
