The episode begins with David, who has come to the clinic to see Dr Christian about a troubling skin infection in his armpit. Dr Christian diagnoses the condition as Hidradenitis Suppurativa, caused by blocked sweat glands. Having already tried antib... (more)iotics without success, Dr Christian prescribes a temporary treatment of strong steroids, although these do improve the condition they are not a long term solution and David is sent to see a plastic surgeon. At St John’s Hospital in Livingston, David is given a skin graft which completely removes the infected skin and replaces with layers of healthy skin taken from David’s thigh. We revisit a relieved David four months after his surgery to see the condition completely cured. Next through the clinic doors was a now 9 year-old Nancy, a year earlier Nancy came to see Dr Christian about a large number of warts on her hands. After freezing the warts and prescribing a cream, Dr Christian finds Nancy’s hands are now completely wart free.
