Convey the horror of being slathered (слэш)

"Jon opens his mouth to answer, and abruptly- can’t find the words. He presses his lips closed, a thin line of stress, closes his eyes because he can’t tolerate the worried expression on Martin’s face, no one came for him, and shakes his head minutely. The movement pulls on a raw patch on his neck, just below his earlobe. It stings. And, just like that- he’s out of his body, in a daze of unfeeling unreality."
