〔《活》〕阴症小便不利，手足厥冷，脉微细者，不宜服利小便冷滑药，但服返阴丹，并取脐下
石门穴灸之。（方论见阴毒返阴丹。）

[From *Huoren Shu* (Book of Living Persons)] In Yin syndromes presenting with difficult urination, cold extremities, and a faint and fine pulse, one should not administer diuretic drugs that are cold and slippery in nature. Instead, only administer Fanyin Dan (Return to Yin Pill) and moxa the Shimen (Stone Gate, CV5) acupoint located below the umbilicus. (Formula discussion see "Yin Toxin Fanyin Dan".)
[From *Jiyan Fang* (Collection of Proven Prescriptions)] For Taiyang disease (Exterior Syndrome of the Hand-Taiyang Bladder Channel) presenting with urinary retention, select YinGu (Yin Valley, KI10) and YinLingQuan (Yin Mound Spring, SP9).
After Taiyang disease, if difficult urination occurs. (See section on "Urinary Retention".)
If difficult urination occurs after sweating: If Taiyang disease was treated with excessive sweating leading to continuous leakage of sweat, symptoms such as aversion to wind, difficult urination, and difficulty flexing/extending the limbs will arise; Guizhi Fuzi Tang (Cinnamon Twig and Aconite Decoction) is indicated. (Formula discussion see "Spontaneous Sweating".)
If Taiyang Wind-strike syndrome is treated with fire methods to force sweating, the pathogenic wind is constrained by the heat, causing blood and qi to overflow abnormally. Symptoms include yellowing of the body, excess Yang and deficiency of Yin, desire for epistaxis, and difficult urination. (Formula discussion see "Head Sweating".)
If Shaoyin disease (Interior Syndrome of the Hand-Shaoyin Heart Channel / Foot-Shaoyin Kidney Channel) is treated with fire methods to force sweating, symptoms such as cough, diarrhea, delirious speech, and difficult urination will occur. (Discussion see "Hypochondriac Pain".)
There are two types of difficult urination following purgation:
1. If the pulse is slow, floating, and weak, with aversion to wind and cold, and purgation is mistakenly applied, symptoms of hypochondriac fullness, jaundice, neck stiffness, and difficult urination will arise. (See "Hypochondriac Pain".)
2. If Yangming Stomach Excess syndrome presents with fever, aversion to cold, and a floating-tight pulse, and purgation is mistakenly applied, symptoms of abdominal fullness and difficult urination will arise. (Discussion see "Stomach Excess".)
For hypochondriac pain, jaundice, and difficult urination: If Yangming Stomach Excess has not yet been purged, Xiaochaihu Tang (Minor Bupleurum Decoction) is indicated. If purgation has already been applied and the patient cannot eat and has neck stiffness, Chaihu (Bupleuri Radix) is contraindicated. (Discussion see "Hypochondriac Pain".)
When the Shaoyin pulse is absent, Kidney Qi is weak, and essence and blood are deficient, rushing Qi (Ben-Qi) presses urgently upward into the chest and diaphragm. Ying-Qi (Nutritive Qi) gathers abnormally, and blood stagnates below the heart. Yang Qi retreats downward, and heat returns to the inner thighs. Interaction between heat and Yin causes insensibility of the body; this is called Corpse-Jue (Shi-Jue), and Qimen (Liver 14, LR14) should be needled.
If Taiyang disease is not cured by purgation and then sweating is reapplied, both exterior and interior become deficient. The patient may experience Mao (vertigo/fainting). Patients with Mao will recover spontaneously through sweating. This is because sweating harmonizes the exterior. Once the interior is harmonized, purgation may then be considered. (*Note*: There must be interpolations or missing text around "De Li He" [Obtain Interior Harmony]. "De" [Obtain] is likely a typo for "Ruo" [If]. "Li He" [Interior Harmonized] is likely "Li Wei He" [Interior Not Yet Harmonized], missing the character "Wei" [Not].)
If there is diarrhea with undigested food, a deep-slow pulse, facial redness, and slight body heat, recovery will occur through Du-Mao (depression and vertigo) followed by sweating. (Discussion see "Diarrhea".)
If there is difficult urination, alternating difficulty and ease of defecation, asthma, vertigo, and inability to lie down, Dachengqi Tang (Major Order the Qi Decoction) is indicated. (Discussion see "Diarrhea".)
All cases affected by Cold result in Jue (cold extremities/reversal), Du-Mao (depression/vertigo), insensibility, oral tension preventing speech, and tremors/shivering. (Discussion see "General Principles".)
If there is vertigo and Mao, hardness below the heart, and neck stiffness without prior treatment via sweating, purging, or vomiting, it is classified as Bing-Bing (Combined Disease); DaZhui (Governing Vessel 14, GV14), Fei-Shu (Bladder 13, BL13), and Gan-Shu (Bladder 18, BL18) should be needled. (Discussion see "Neck Stiffness".)
If after sweating, purging, or vomiting, the pulse is faint and Qi rushes upward to the throat, Wei (flaccidity syndrome) will form. (Discussion see "Qi Rushing Upward".)
In Shaoyin disease, if the patient desires sleep, and diarrhea stops but is followed by vertigo and Mao, the prognosis is fatal. (Discussion see "Desire to Sleep".)
