This Bodyshock Special features 13-year-old Twinkle Dwivedi who, for nearly two years, has inexplicably cried tears of blood. The spontaneous bleeding, which happens almost daily, also comes from her head, hands and feet. The programme follows Twinkle and her mother as they travel from their home in northern India to explore the cause of her extraordinary condition, visiting a Catholic Bishop to ask whether her bleeding is stigmata, bathing in the Ganges and visiting an alternative medicine centre. But when a world expert on blood disorders flies in to examine her, Twinkle's journey of discovery edges closer to some uncomfortable possibilities.
