He put his head out of the door and summoned a nurse who came with a black bag. From the bag, Scholar Phelps took a skin-blast hypo and a small metal box, the top of which held a small slender, jointed platform and some tiny straps. He strapped my finger to this platform and then plugged in a length of line cord to the nearest wall socket. The little platforms moved; the one nearest my wrist vibrated rapidly across a very small excursion that tickled like the devil. The end platform moved in an arc, flexing the finger tip from straight to about seventy degrees. This moved fairly slow but regularly up and down.
"I'll not fool you," he said drily. "This is going to hurt."
He set the skin-blast hypo on top of the joint and let it go. For a moment the finger felt cold, numb, pleasant. Then the shock wore away and the tip of my finger, my whole finger and part of my hand shocked me with the most excruciating agony that the hide of man ever felt. Flashes and waves of pain darted up my arm to the elbow and the muscles in my forearm jumped. The sensitive nerve in my elbow sang and sent darting waves of zigzag needles up to my shoulder. My hand was a source of searing heat and freezing cold and the pain of being crushed and twisted and wrenched out of joint all at the same time.
Phelps wiped my wet face with a towel, loaded another hypo and let me have it in the shoulder. Gradually the stuff took hold and the awful pain began to subside. Not all the way, it just diminished from absolutely unbearable to merely terrible.
I knew at that moment why a trapped animal will bite off its own foreleg to get free of the trap.
From the depths of his bag he found a bottle and poured a half-tumbler for me; it went down like a whiskey-flavored soft drink. It had about as much kick as when you pour a drink of water into a highball glass that still holds a dreg of melted ice and diluted liquor. But it burned like fury once it hit my stomach and my mind began to wobble. He'd given me a slug of the pure quill, one hundred proof.
As some sort of counter-irritant, it worked. Very gradually the awful pain in my hand began to subside.
"You can take that manipulator off in an hour or so," he told me. "And in the meantime we'll get along with our testing."
I gathered that they could stop this treatment anywhere along the process if I did not measure up.
