in the throat, with a continuous but fruitless desire to hawk; is urged to swallow the mucus. The paralytic tendency in this symptom is evident. ‘Hawking of mucus, with a pain in the throat pit’ is another well-confirmed symptom. All throat pain is aggravated by stooping.
Voice and Air Passages
Speechlessness from paralysis of the organs of speech, and hoarseness are the main characteristics.
As Kent laconically states, ‘the Causticum patient has trouble with the voice.’ These troubles may be of catarrhal origin, from exposure to cold etc., or due to overuse of the voice, as in singers or public speakers; but they can also come on idiopathically and all of a sudden; a complete loss of voice from paresis of the nervus recurrens, the musculus transversus, or other forms of paralysis. ‘The muscles of the larynx fail to act; cannot speak a word aloud, in spite of much exertion.’
Hoarseness or aphonia are usually worst in the morning (opposite to Carbo vegetabilis), but an aggravation in the evening is also noted. Whereas talking or straining the voice frequently aggravates, Mezger also relates a case of paresis of transversus where the state became worse from not using the voice. In this case the voice became clear by mechanically removing the mucus from the larynx, but due to the paresis of the muscles, it accumulated again when the patient did not talk.
A proving symptom: ‘The voice is obstructed for several mornings, as though a wedge were in the larynx which should be ejected.’
The dryness and/or accumulation of mucus, as well as the sensations of rawness, burning, scraping, soreness, are very prominent in the air passages and particularly in the chest. ‘Hoarseness with rawness, burning and soreness of chest’ is given by Hering in highest degree.
Sore pressive pain in the larynx on blowing the nose.
Cough, Respiration and Chest
The Causticum cough is attended by a sensation as if the patient could not get deep enough to eject the mucus; he ‘cannot get under the mucus’,
