When mother-of-one Alexandra Gerrard went to the accident and emergency department of Epsom Hospital, the pain was unimaginable.
The 34-year-old was in agony - so much so that she couldn't even walk.
But despite her suffering, NHS doctors told her she should take some painkillers and go home.
What they missed was a condition that changed the course of her life forever.
It all started when she was enjoying a well-deserved break in Miami, away from her job as a primary school worker.
