This week Rachel is joined by the author and activist Tilly Rose, who spent 20 years in and out of hospital as a ‘medical mystery’. When Tilly was told by a doctor all she could be offered was 'comfort care' rather than a diagnosis, she decided to share her situation online. With the help of the internet, she finally received the treatment she needed. Tilly’s now documented her journey in the award-winning book ‘Be Patient’.
