• Kidneys—renal pelvis/ureter (right > left) — Paroxysmal nephritic colic with tearing, cutting pains shooting to groin/testicle or labium; nausea, restlessness, instant relief after passing gravel or a small calculus [Clarke], [Boger], [Boericke].
• Bladder/neck of bladder — Intolerable urging, scant, hot urine, burning urethra, tenesmus; brick-dust deposit; children cry before micturition [Hering], [Phatak].
• Prostate/seminal tract (reflex) — Drag to testicle with right ureteric storms; retraction and spermatic cord pain during colic [Clarke], [Boger].
• Gastro-duodenal (reflex emesis) — Retching and vomiting of bile/mucus from renal spasm; faintness and cold sweat [Allen], [Boericke].
• Peritoneal/parietal nerves — Writhing, cannot keep still; intolerance to jar; must press/heat the side; micro-cases note “falls on the bed, doubles up” [Clarke], [Phatak].
• Uric diathesis / gravel — Red, gritty sediment, high-coloured urine, waking at night to void gritty drops; uric-acid habit with diet indiscretions [Boger], [Phatak].
• Children — Dysuria with screams, sand in diaper, restless, hands to genitals; reflex belly-ache relieved after urine with sediment [Hering], [Clarke].

• Passing urine/gravel — When grit or a small stone passes, the agony suddenly ceases, confirming the calculus aetiology [Clarke], [Boger].
• Warm applications; hot drinks — Heat eases spasm along right ureter; warm water in sips quiets nausea [Boericke], [Phatak].
• Pressure / bending forwards / doubling up — Bending the body and firm hand-pressure to flank dulls the tearing; a bedside posture [Clarke].
• Profuse water later (between paroxysms) — Free flow keeps grit moving; patient improves with copious bland fluids when pain is absent [Boger].
• Rest (after the paroxysm) — Sleep comes when the stone drops into the bladder; soreness remains but pain is gone [Hering].
• Sweat breaking — A gentle perspiration coincides with relaxation of spasm [Boericke].
• Avoiding acids/fats and salt-rich fare — Uric diathesis eases with simple diet; attacks diminish (clinical hygiene) [Phatak].
• Rubbing the course of ureter — Strokes from kidney to groin give transient relief (nursing note) [Clarke].

• Right side — Kidney pain and ureteric shoot predominate on the right; pains travel kidney → groin/testicle [Boericke], [Boger], [Clarke].
• Motion, jar, stepping — Jolt renews tearing; patient writhes yet fears movement [Boger], [Hering].
• Cold drinks / exposure — Chill precipitates spasm and burning on passing urine [Clarke], [Phatak].
• After irritation/dietary excess — Rich meats, alcohol, sour wines excite uric sand and colic relapses [Phatak], [Clarke].
• During urination — Tenesmus and knife-like pain increases while voiding, then eases as grit passes [Hering].
• Night / early morning — Paroxysms wake the patient, with nausea, sweat, and restlessness [Boericke].
• Pressure over kidney at the height of pain — Deep pressure intolerable then; only light steady support helps (nuance) [Clarke].
• Suppression of urine / holding — Increases back-pressure and colic likelihood [Boger].

Extreme restlessness with fear that the pain will return; the sufferer cannot lie still, throws himself about, holds the right side, and implores for heat and help [Hering], [Clarke]. Patience is lost; the temper is irritable, yet speech is short because nausea rises with the pain. Anxiety centres in the act of urination—he dreads the knife-like urethral burn until the grit comes; when it does, a wave of relief and gratitude replaces the turmoil, echoing the amelioration already noted. Children become frantic and scream before urine; when coarse grains appear in the diaper they fall asleep—an oft-repeated micro-case in the literature [Hering], [Phatak]. Consolation is useless during the paroxysm; company that acts (heat, rubbing) is welcomed, conversation is not. Between attacks the mood is cautious and compliant with diet, but any chill or dietary slip stirs anticipatory dread. Unlike Cantharis, the mental picture is not sexual irritability with furious tenesmus; unlike Berberis, there is less anxiety about motion away from the hearth—Ocimum will try to move if he thinks the gravel will drop. The mind quiets as urine flows freely, which links psyche to emunctory function throughout the entry.

Head reels in the crest of colic; face is pale, lips cold; cold sweat beads the forehead [Clarke]. A dull frontal ache may herald an attack when the uric sand accumulates; after gravel passes the head clears—an organ echo. Loud talking and jar irritate the head and flank simultaneously; the patient wants stillness and heat to the side. Nausea and retching pull the scalp tight; on vomiting, a momentary head relief arrives, then the flank resumes. Head symptoms are reflex; there is no primary congestive headache picture. Compared: Lycopodium (right-sided colic with gas, 4–8 p.m. flatulence), Colocynthis (bending double > but intestinal, not renal), Sarsaparilla (head relieved after urine with end-of-micturition pain).
