淋病有五。一曰热淋（血淋）。二曰寒淋（膏淋）。三曰气淋。四曰劳淋。五曰石淋。五淋之中。小儿有所
患者。惟寒热气之三证外。劳石二证。虚极所致。小儿未亲色欲，故无患者。内石淋恐儿本怯肾弱者有之。亦
千人中无一矣。今并具五淋之证于下。
热淋者。因热乘小肠膀胱二经。皆主水。水入小肠。传于膀胱。行于水道。出于阴中。而为小便也。故阴为
水液之路。膀胱为津液之府。热则水道燥爆。水液行涩。致水道不利。小便淋沥。因名曰淋。其候出少而起数。
小腹急痛。引脐连茎中痛也。热甚者溺血，故亦曰血淋。血得热则流散。渗入于胞，随淋溺而下也。
寒淋者。因寒冷干于二经而作。其候先寒战而后溺之。是邪气与正气交争也。寒气胜则发寒战。正气胜则寒
战解而得溺。溺则出少涩滞。小腹连茎中而痛。寒甚者溺白如稀膏。故亦曰膏淋。亦如痢下热则便血。寒则便脓
也。痢下者寒热搏于大肠也。今淋者寒热搏于小肠也。
气淋者。小儿因怒而啼。气入二经。留滞不散。邪正相搏。胞内气胀。其候每溺则脐下憋膨。水道涩不能
下。茎中相引而痛。常有余沥也。
劳淋者。因房事过度。肾虚精竭。气通于阴。水道干涩之所为也。肾与膀胱为表里。今肾虚精竭。则膀胱亦
虚。不能约制其水。故水液频数而下。水道干燥。则不能通利。其候尿留茎内。数起不出。引小肠连茎而痛也。
石淋者。小者为沙。大者为石。皆云肾主水。水为热结。化而为石。其言虽近。而不知其本也。且肾有
二脏。左者为肾。右为命门。主水而为壬。圣济经云。壬者一水一石之谓欤。不知一水一石之道语。未达生化之
妙。本太一精真在上。兆于水。立于石。是肾中本有真之物也。患者乃真精化而真物出焉。其候沙石从水道中
出。塞痛闷绝。故痊者鲜矣。

Lumbago (Lin syndrome) encompasses five types. The first is called Heat Lin (Blood Lin). The second is Cold Lin (Gao Lin). The third is Qi Lin. The fourth is Labor Lin. The fifth is Stone Lin. Among the five types of Lin, children are prone to the Cold, Heat, and Qi syndromes. The Labor Lin and Stone Lin syndromes are caused by extreme deficiency. Since children have not engaged in sexual activity, they do not suffer from Labor Lin. As for Stone Lin, it may occur only in those with innate frailty and weak Kidneys, but this is extremely rare, perhaps one in a thousand. The manifestations of all five types of Lin are detailed below.
Heat Lin arises when heat pathogens invade the Small Intestine and Bladder meridians, both of which govern water metabolism. Water enters the Small Intestine, transmits to the Bladder, travels through the water pathways, and exits via the urethra as urine. Thus, the urethra serves as the pathway for fluid passage, and the Bladder is the reservoir for body fluids. When heat is present, the water pathways become dry and irritated, causing fluid flow to be sluggish and obstructed, resulting in dribbling urination, hence termed "Lin." Symptoms include scanty urine output with frequent voiding, urgency and pain in the lower abdomen radiating to the umbilicus and penis. If heat is severe, hematuria occurs, thus it is also called Blood Lin. Blood exposed to heat scatters and infiltrates the bladder/pelvic cavity, discharging along with the dribbling urine.
Cold Lin results from cold pathogens interfering with these two meridians. Its hallmark is chills preceding urination, indicating a struggle between pathogenic factors and healthy Qi. When cold dominates, chills occur; when healthy Qi prevails, chills subside and urination becomes possible. Urination is scanty and obstructed, with pain in the lower abdomen radiating to the penis. In cases of severe cold, the urine appears white and viscous like thin paste, hence also called Gao Lin. This parallels dysentery: heat causes bloody stools, while cold causes purulent stools. Dysentery involves the binding of cold and heat in the Large Intestine, whereas Lin syndrome involves their binding in the Small Intestine.
Qi Lin occurs when children cry out of anger, causing Qi to reverse and enter these meridians, where it stagnates and fails to disperse. Pathogenic and healthy Qi clash, leading to abdominal distension within the pelvic cavity. Symptoms include a feeling of fullness and bloating below the umbilicus during urination, obstruction in the water pathways preventing smooth flow, pulling pain in the penis, and often post-void dribbling.
Labor Lin is caused by excessive sexual activity leading to Kidney deficiency and essence depletion. Qi connects to the genital region, causing the water pathways to become dry and sluggish. The Kidney and Bladder are exterior-interior paired organs; thus, Kidney deficiency leads to Bladder deficiency, impairing its ability to control water retention. Consequently, urine flows frequently. Dryness of the water pathways prevents free flow. Symptoms include urine retention within the penis, frequent urges without voiding, and pain radiating from the Small Intestine to the penis.
Stone Lin refers to small particles as sand and larger ones as stones. It is commonly said that the Kidney governs water, and when water is bound by heat, it transforms into stones. While this view is close to reality, it misses the root cause. There are two aspects of the Kidney: the left is the Kidney proper, and the right is the Mingmen (Gate of Life), governing water and corresponding to the Heavenly Stem Ren. The *Shengji Jing* asks: "Does Ren imply one water and one stone?" This understanding fails to grasp the subtleties of generation and transformation. Fundamentally, the Supreme One's true essence resides above, manifesting in water and establishing itself in stone; this is the true substance inherent in the Kidney. Patients expel this true substance transformed from their true essence. Symptoms involve sand or stones passing through the water pathways, causing blockage, severe pain, and even fainting; recovery is rare.
