• Labyrinth (inner ear) & 8th nerve — Tinnitus (ringing/roaring), vertigo with nausea, oscillopsia, staggering; relative deafness, especially for human voice; classic in Ménière’s and drug-ototoxic pictures [Clarke], [Allen], [Boger].
• Auditory conduction (middle ear catarrh) — Post-influenza or catarrhal deafness with fullness and noises, worse motion/noise, better absolute quiet [Clarke], [Boericke].
• Head—vascular — Throbbing temporal headaches, pulsation in head/ears, often with sweats and feverish heat in rheumatic/influenza contexts [Hughes], [Clarke].
• Nerves—nausea centre — Vertigo with gastric revolt, sea-sick type, from the least motion; overlap with motion-sickness remedies [Boger], [Farrington].
• Heart–rheumatic field — Rheumatic febrile states with sweating, palpitation from effort; secondary use when ear and head keynotes coexist [Boericke], [Clarke].
• Kidney/urine (toxic echo) — Dark/albuminous urine and sweats in salicylism; comparative guidance in febrile rheumatics with ear-symptom cluster [Hughes].
• Mind (sensory irritability) — Noise-intolerance, irritability and low spirits from incessant ringing; mental dulness in close, hot rooms [Clarke], [Allen].

• Absolute rest; lying perfectly still — Vertigo and nausea abate when head is kept motionless; tallies with vestibular origin [Clarke], [Boger].
• Quiet, dark room — Noise and light cease to provoke tinnitus/vertigo; the patient seeks darkness and silence [Clarke].
• Head high / supported — Propped head reduces throbbing and motion-provoked spinning [Allen].
• Open, cool air (without wind on ear) — Head clears; stuffy rooms intensify dullness; avoid draught directly on ear [Clarke].
• After gentle perspiration — Feverish pressure and head noises lessen when a light sweat comes on [Hughes], [Boericke].
• After food in small portions — Hunger-worsened nausea/vertigo ease with small, frequent meals [Allen].
• Firm pressure over mastoid/ear — Some note transient comfort from steadying the part (clinical) [Clarke].
• Even, slow breathing — Paced respiration steadies nausea and panic during spins [Boger].

• Motion of head/body (least jar, turning in bed, rising) — Spins, staggering, and vomiting from the slightest movement [Clarke], [Boger].
• Noise, music, conversation — Tinnitus grows intolerable; hearing of speech specially fails amid noise [Clarke].
• Close, hot rooms / night heat — Head throbs; noises louden; mental dulness increases [Hughes], [Clarke].
• After influenza / febrile rheumatism — Labyrinthine catarrh and tinnitus persist as sequelae [Clarke], [Boericke].
• Alcohol / strong coffee — Heighten throbbing and noises; precipitate spins (clinical) [Clarke].
• Rapid visual flow (reading in trains, screens) — Oscillopsia and nausea reignite (motion–visual coupling) [Boger].
• Sudden head movements / stooping — Bring on blackness and pitching sensation [Allen].
• Quinine/salicylate exposure — Drug-induced ringing–deafness and vertigo echo the remedy signature [Hughes], [Clarke].

The incessant ringing and roaring wear down the mind into irritability, discouragement, and noise-intolerance; the patient becomes withdrawn, preferring silence and a darkened room [Clarke]. Anxiety spikes with any hint of motion, knowing a turn of the head will bring the spin; this anticipatory dread itself provokes shallow breathing and pallor during attacks, which tallies with the modality worse from motion already noted. Concentration fails amidst tinnitus; reading lines or following conversation is thwarted by auditory blur, and the sufferer answers amiss from imperfect hearing, further depressing spirits [Allen]. Unlike the jealous, torrential talk of the serpents, or the terrified restlessness of Arsenicum, this is a low, irritable despondency born of sensory bombardment. Relief in the open, cool air or after a light sweat brings a brief lift in mood, echoing the Better For list. Suspicion that others mutter fuels social avoidance; yet in quiet company the mind steadies, provided no one speaks loudly or suddenly. After influenza, a “fog” sits on the mind with sluggish memory; as tinnitus settles, thought brightens—cross-link to Head and Ears. A micro-case: a clerk with post-influenza deafness grows morose from office noise; when allowed to work in a silent side room and dosed with Nat-sal., vertigo episodes cease and his civility returns [Clarke] [Clinical].

Headache is throbbing and vascular, often temporal, with a surging in the ears and heat of head disproportionate to skin temperature [Hughes], [Clarke]. Stooping, sudden turning, or stepping off a kerb makes the room wheel; the patient clutches the bed or chair and dares not move, a picture aligning precisely with the modality better absolute rest. Pulsation heightens in a close, hot room and decreases in the open, cool air, providing a management cue. The scalp feels tight, the brow heavy as if a band were drawn; reading, especially in moving vehicles, brings on oscillopsia and nausea [Boger]. After a gentle perspiration, headache softens and the roaring subsides for a time (Better For: gentle sweat). Compare Cocculus (vertigo from loss of sleep and motion, greater gastric atony), Theridion (sound and light hyperaesthesia with seasick nausea), and Conium (vertigo on turning in bed, without the salicylate tinnitus stamp) [Boger], [Farrington].
