White room of torture

I get migraines. They're pretty awful, these explosions of pain. I liken them unto a non-existent torture technique that could possibly exist in the future. It goes like this.

Imagine you have been grabbed by the muscles connecting your neck to your shoulders, and thus dragged into a white room full of white and yellow lights. You are then thrown head first onto a hot metal table that begins to sear you. An injection is given to you and you are quickly paralyzed. Your captors use metal tongs to tug at the flesh and muscle on your neck and skull until they are pulled tight. And then, when you are feeling discomfort, they take a huge syringe with a needle a centimeter in diameter and they stab it into your skull. And before you can stop screaming, they inject acidic poison into your skull, where it sloshes with your brain. The burning liquid licks and rips at every morsel of soft tissue, and when you move your head it throbs and pulsates in your too-full head. Exploding seems imminent, yet it never happens.

And you go on like that until you take a pill that diffuses the pain for a few hours. But it always comes back shortly, like a revisit to the room and the needle inserted anew.
