It’s a bright, hot day. Outside, the city is baking; through a window I can see a cloudless blue sky. But I am inside, shivering, covered with blankets and hugging a heat pack.
Jammed tightly over my wet hair, secured with a chin strap, is a silicone cap filled with liquid circulating at -4 degrees Celsius. The pain is excruciating – like a frozen clamp screwed tight around my skull. Bits of white gauze have been tucked under the edge of the cap so it doesn’t burn my skin, and I’ve had painkillers, a sedative and chocolate.
