Great sluggishness; he is disinclined to rise in the morning, and after rising is indolent. Thinking is hard for him when it is of a comparative nature but not when it is creative, e.g. he can easily write out a case or problem, but finds it difficult to select remedies; writes treatises with facility, but finds it hard to classify and determine place in systems.

Stinging in left temple. In the evening itching on the head and nape of neck.


On awaking, burning pain internally above the canthus. (The flickering used to be followed by headache; after the remedy the flickering appeared alone). She lost her vision; everything seemed very far, as if a veil were drawn before her; it blazed and flickered before her eyes; she was obliged to lie down; even when closing the eyes flicker-ing continued; thereupon very weak; and the head much affected.


During the rushing sound her hearing is not so good as formerly, notwithstanding the rushing. Roaring in the ears. All loud noises make to strong an impression on her; Aconite relieved.

The anus protrudes and is painful, especially while sitting, without hemorrhoidal bunches, which he usually has frequently; this passes off, returns again later, and then hemorrhoidal tumors appear. A heaviness in the perineal region, which he has had for a long time, now becomes noticeable at every step; it seems to him as if a lump were lying there. Desire to go to stool appears later and less urgent than usual.


Diarrhoea without colic with the vomiting and vertigo at night.

After a long time he has a little scanty discharge, with much urging (tenesmus). Instead of two stools as usual, she now has only one. Stool is not hard, still the discharge becomes more difficult towards the end. No stool for several days (after first dose of 30th).

Inferior Extremities

In the evening while sitting, and later, peculiar drawing in the right thigh; it began in the hip and passed downward, with a cold sensation below the knee; it felt everywhere cold internally, but not to the touch; still external warmth was agreeable. Being internally cold, it draws from the hip to below the knee without external coldness; warmth is agreeable. In the afternoon her knees trouble her. Swelling of the feet (secondary effect of the bite). The little toe pains as if pressed in walking.


Paroxysm; she awakes, after a short sleep, at 11 o’clock; already in sleeping she felt the vertigo, and was awakened thereby; could not remain lying; tried to reach the chamber pot, but fell down in a swoon; cold sweat broke out; she strains to vomit till this takes place, and is repeated every quarter of an hour, during which icy perspiration breaks out all over her; at the same time she has several attacks of diarrhoea without abdominal pain; at first she vomited acrid slimy water, almost preventing her from regaining her breath; at length she felt entirely empty at the stomach; the least motion again brought on vertigo and vomiting; she dares not stir, and when her eyes closed, the lids falling, as if were, from being tired, vertigo and nausea immediately returned; after taking Mentha pip. she had some hours of sleep; in the morning on rising, the nausea came again and she vomited bile; her throat felt as if scalded; her back was tired, pulse accelerated, together with headache. She is so weak that she cannot stand long; she becomes tremulous and perspires. Very weak after the flickering before the eyes. He feels exhausted and tremulous, but without trembling. Every penetrating sound and reverberation penetrates through her whole body, particularly through the teeth, and increases the vertigo, which then causes nausea. Great exhaustion; he is quite unable to work. Without feeling pain, she has such a queer sensation in her whole head that she cannot describe it. Pains in all the bones, as if every part would fall asunder; feels as if broken from head to foot; thereupon violent coldness so that nothing would harm her; without thirst (after the bite).
