Dr Christian meets a girl with asymmetric breasts and looks after a man whose penis has curved right around, while Dr Pixie takes on a shocking case of painful scalp pustules.

The mobile truck reaches Great Yarmouth where the doctors discover why curry helps a man with a painful bottom. Then Dr Dawn and Dr Pixie both put their own bodies on the line as they undergo different types of mammograms to test for breast cancer.

And, in the series' ongoing celebration of extraordinary people, the programme features a man with narcolepsy to discover what life is like when you can't help nodding off.
