Saliva becomes thick and foul-tasting; the tongue clings irritatingly to the teeth and the roof of the mouth .... A lump seems to form in the throat ... severe pain is felt in the head and neck. The face feels full due to the shrinking of the skin. Hearing is affected, and many people begin to hallucinate... then come the agonies of a mouth that has ceased to generate saliva. The tongue hardens into "a senseless weight, swinging on the still-soft root and striking foreignly against the teeth." Speech becomes impossible, although sufferers have been known to moan and bellow.
Next is the "blood sweats" phase, involving "a progressive mummification of the initially living body." The tongue swells to such proportions that it squeezes past the jaws. The eyelids crack and the eyeballs begin to weep tears of blood. The throat is so swollen that breathing becomes difficult, creating an incongruous yet terrifying sense of drowning.
Finally ... there is living death, crawling on your hands and knees: "your lips disappear as if amputated, leaving low edges of blackened tissue; your teeth and gums project like those of a skinned animal, but the flesh is black and dry as a hank of jerky; your nose withers and shrinks to half its length, and the nostril-lining showing black; your eyes set in a winkless stare, with surrounding skin so contracted as to expose the conjunctiva, itself as black as the gums...; your skin [had] generally turns a ghastly purplish yet ashen gray, with great livid blotches and streaks; your lower legs and feet ... are torn and scratched by contact with thorns and sharp rocks, yet even the freshest cuts were so many scratches in dry leather, without a trace of blood"
