A 29-year-old woman had a two-year history of intermittent burning in her feet, restless legs, back spasms and tremulousness on wakening. On occasions, her legs ‘left’ her, resulting in falls. She had pins and needles in her face, hands and legs. She had episodes of blurred vision. Her health deteriorated in the year before her first neurology inpatient assessment. Her symptoms continued with tremor, weakness in her legs, cold and burning feelings in her feet, pain in her eyes, blurred vision, pins and needles in her hands and feet, jerks and seizures. Sometimes she was conscious but unresponsive during 30-second seizure-like episodes.
