  Don’t know this one actually! My mum always told me not to sit with my legs in a draught though, maybe that’s it…

  They’re sort of a cross between frostbite and trench foot (ew!)
  You get them when your extremities, like your toes or fingers, are exposed to cold and humidity – because your cells can’t cope with all the changing conditions.
