It's been called a psychological disorder. Sufferers have been ridiculed and labelled perverts. Yet the compulsion to be free of a limb is no imaginary illness. The feelings the condition generates are extraordinarily powerful — so strong that sufferers often seek out the most radical of treatments, and a few unorthodox surgeons risk their reputations to assist.
Now we may know why: the condition's deep neurological roots are being unearthed, with startling implications for sufferers, the medical profession and our own understanding of ourselves.
In this disturbing story from new science and technology publisher MATTER, acclaimed writer Anil Ananthaswamy delves into the science and accompanies an underground group of sufferers who travel across the world to get the illicit surgery they crave. Join him on a journey that reveals what it's like to be at war with your own body.
