Context
The lived medical texture of kicking, catalogued in Poor Tony's fastidious idiom against the abjection it describes: fifty kilos, squash-colored skin, the bunny-pink eye, the spigot nose. The clause "his symptoms themselves developed symptoms" is the theme's exact description of how Withdrawal compounds — a fractal worsening he can only chart "with morbid attention," a connoisseur of his own dissolution.
