人之一身，屈伸俯仰，惟腰是赖，故病则多痛。自足太阳以至奇经别络等并令腰痛者，或经之所至，或络之
所系，或脉之所过，世以为尽属肝肾者误也。
足太阳脉令人腰痛，引项脊尻背如重状。（足太阳脉，别下项，循肩 内，挟脊抵腰中，别下贯臀，故令人
病如是也。按∶新校正云∶“甲乙经贯臀作贯胂，刺疟论注亦作贯胂，三部九候论注作贯臀。”）刺其 中太阳
正经出血，春无见血。（ 中，委中也。在膝后屈处， 中央约文中动脉，足太阳脉之所入也。刺五分，留七
呼，灸三壮。太阳合肾，肾王于冬，水衰于春，故春无见血也。）少阳令人腰痛，如以针刺其皮中，循循然不可
以俯仰，不可以
顾。足少阳脉，绕髦际，横入髀厌中，故令腰痛，如以针刺其皮中，循循然不可以俯仰。胆足少阳之脉，起于目
锐，上抵头角，下耳后，循颈，行手阳明之前，至肩上，交出手少阳之后。其支别者，目锐 下入大迎，合手少
阳于 下，加颊车，下颈，合缺盆。故不可以顾。按∶新校正云∶“甲乙经行手阳明之前，作行手少阳之前也。”
刺少阳成骨之端出血，成骨在膝外廉之骨独起者，夏无见血。（成骨谓膝外近下， 骨上端，两起骨相并间，陷
容指者也。 骨所成柱膝髀骨，故谓之成骨也。少阳合肝，肝王于春，木衰于夏，故无见血也。）阳明令人腰痛
不可以顾，顾如有见者，善悲。（足阳明脉起于鼻交 中，下循鼻外，入上齿中，还出挟口环唇，下交承浆，
却循颐后下廉，出大迎。其支别者，从大迎前，下人迎，循喉咙，入缺盆。又其支别者，起胃下口，循腹里，至
气街中而合以下髀，故令人腰痛不可顾，顾如有见者。阳虚，故悲也。）刺阳明于 前三 ，上下和之出血，
秋无见血。（内经、中诰流注图经，阳明脉穴俞之所主，此腰痛者，悉刺 前三 ，则正三里穴也。阳明合脾，
脾王长夏，土衰于秋，故秋无见血。按∶新校正云∶“甲乙经 作 。” 音委。）足少阴令人腰痛，痛引脊内
廉。（足少阴脉，上股内后廉，贯脊属肾，故令人腰痛，痛引脊内廉也。按∶新校正云∶“全元起本脊内廉作
脊内痛，太素亦同。此前少足太阴腰痛证，并刺足太阴法，应古脱简也。”）刺少阴于内踝上二 ，春无见血，
出血太多，不可复也。（内经、中诰流注图经，少阴脉穴俞所主，此腰痛者，当刺内踝上，则正复溜穴也。复
溜在内踝后上二寸，动脉陷者中。刺三分，留三呼，灸五壮。）厥阴之脉令人腰痛，腰中如张弓弩弦。（足厥
阴脉，自阴股，环阴器，抵少腹。其支别者，与太阴少阳结于腰髁下，挟脊第三第四骨空中，其穴即中 下 。
故腰痛则中如张弓弩之弦也。如张弦者，言强急之甚。）刺厥阴之脉，在 踵鱼腹之外，循之累累然，乃刺之。
（踵者，言脉在 外侧下，当足跟也。
情势如卧鱼之腹，故曰鱼腹之外也。循其分肉有血络累累然，乃刺之。此正当蠡沟穴分，足厥阴之络，在内踝
上五寸，别走少阳者。刺二分，留三呼，灸三壮。按∶经言厥阴之脉，注言厥阴之络，新校正疑是经误，非也。
盖脉者统辞，可以兼络而言，非误也。）其病令人言默默然不慧，刺之三 ，（厥阴之脉，循喉咙之后，上入
颃颡，络于舌本，故病则善言。风盛则昏冒，故不爽慧也。三刺其处，腰痛乃除。按∶新校正云∶“经云善言
默默然不慧，善言与默默二病难相兼。全元起无善字，于义为允。”今改从之。“又甲乙经厥阴之脉不络舌本，
王氏于素问中五处引注，而注厥论与刺热论及此三篇皆云络舌本，注风论痹论二篇不言络舌本，盖王氏亦疑而两
言之也。”）解脉令人腰痛，痛引肩，目KT KT 然，时遗溲。（解脉，散行脉也，言不合而别行也。此足太
阳之经，起于目内 ，上额交巅，上循肩 ，挟脊抵腰中，入循膂，络肾，属膀胱，下入 中，故病斯候也。
又其支别者，从 内别下贯胂，循髀外后廉而下，合于 中。两脉如绳之解股，故名解脉也。）刺解脉在膝筋
肉分间 外廉之横脉出血，血变而止。（膝后两旁大筋双上股之后，两筋之间，横文之处，努肉高起，则 中
之分也。古中诰以 中为太阳之 。当取 外廉有血络横见，迢然紫黑而盛满者，乃刺之，当见黑血，必候其血
色变赤乃止，血不变赤，极而泻之，必行血色变赤乃止，此太阳中经之为腰痛也。）解脉令人腰痛如引带，常
如折腰状，善恐。（足太阳之别脉，自肩而别下循背脊，至腰而横入髀外后廉，而下合 中，故若引带如折腰
之状。按∶新校正云∶“甲乙经如引带作如裂，善恐作善怒也。”）刺解脉在 中结络如黍米，刺之血射以黑，
见赤血而已。（ 中则委中穴，足太阳合也，即膝后屈处， 中央约文中动脉。刺五分，留七呼，灸三壮，此
经刺法也。今则取其结络大如黍米者，当黑血箭射而出，见血变赤，然可止也。按∶新校正云∶“全元起云∶
有两解脉，病源各异，恐误，未详。”）同阴之脉令人腰痛，痛如小锤居其中，怫然肿。
足少阳之别络也，并足少阳经上行，去足外踝上五寸，乃别走厥阴，并经下络足跗，故曰同阴脉也。怫，怒也，
言肿如嗔怒也。（按∶新校正云∶“太素小锤作小针。”）刺同阴之脉，在外踝上绝骨之端，为三 。（绝骨之
端如前三分，阳辅穴也，足少阳脉所行。刺五分，留七呼，灸三壮。）阳维之脉令人腰痛，痛上怫然肿。（阳维
起于阳，则太阳之所生，奇经八脉，此其一也。）刺阳维之脉，脉与太阳合 下间，去地一尺所。（太阳所生，
与正经并行而上，至 下复与太阳合而上也。 下去地一尺，是则承光穴，在锐 肠下肉分间，陷者中。刺七分，
灸五壮。以其取 肠下肉分间，故云合 下间。按∶新校正云∶“穴之所在，乃承山，非承光也。山字误为光。”）
衡络之脉令人腰痛，不可以俯仰，仰则恐仆，得之举重伤腰，衡络绝，恶血归之。（衡∶横也，谓太阳之外络
自腰中横入髀外后廉而下与中经合于 中者。今举重伤腰，则横络绝，中经独盛，故腰痛不可以俯仰矣。一经
作冲绝之脉，传写鱼鲁之误也。若是冲脉，中诰不应取太阳脉委阳、殷门之穴也。）刺之在 阳、筋之间、
上数寸衡居，为二 ，出血。（横居二穴，谓委阳、殷门，平视横相当也。 阳谓浮 穴上侧委阳穴也。筋
之间谓膝后 中两筋之间，殷门穴也。二穴各去臀下横文六寸，故曰上 数寸也。委阳刺七分，留五呼，灸三
壮。殷门刺五分，留七呼，灸三壮。故曰衡居为二 。按∶新校正云∶“详王氏云浮 穴上侧委阳穴也，按甲
乙经委阳在浮 穴下一寸，不得言上侧也。”）会阴之脉令人腰痛，上漯漯然汗出，汗干令人欲饮，饮已欲走。
（足太阳之中经也。其脉循腰，下会于后阴，故曰会阴之脉。其经自腰下行至足，今阳气大盛故痛，上漯漯然
汗出。汗液既出，则肾燥阴虚，故汗干令人欲饮水以救肾也。水入腹已，肾气复生，阴气流行，太阳又盛，故
饮水已又欲走也。按∶漯，他合切，汗出貌。）刺直阳之脉上三 ，在跷上 下五寸横
居，视其盛者出血。（直阳之脉，则太阳之脉，挟脊下行贯臀，下至 中，下循 ，过外踝之后，条直而行者，
故曰直阳之脉也。跷为阳跷所生申脉穴，在外踝下也。 下则 下也。言此刺处在 下五寸，上承 中之穴，
下当申脉之位，是谓承筋穴，即 中央如外陷者中也，太阳脉气所发。禁不可刺，灸三壮。今云刺者，谓刺其
血络之盛满者也。两 皆有太阳经气下行，当视两 中央有血络盛满者乃刺出之，故曰视其盛者出血。按∶新
校正云∶“详上云会阴之脉令人腰痛，此云刺直阳之脉者，详此直阳之脉即会阴之脉也，文变而事不殊。又承
筋穴注云 中央如外，甲乙经及骨空论注无如外字。”）飞阳之脉令人腰痛，痛上怫怫然，甚则悲以恐。（是
阴维之脉也，去内踝上五寸 分中，并少阴经而上也。少阴之脉前，则阴维脉所行也。足少阴之脉，从肾上贯肝
膈，入肺中，循喉咙，挟舌本。其支别者，从肺出络心，注胸中。故甚则悲以恐也。恐者生于肾，悲者生于心。
按∶悲为肺志，注谓生于心，误矣。）刺飞阳之脉，在内踝上五寸，（按∶甲乙经作二寸。）少阴之前，与阴
维之会。（内踝后上五寸，复溜穴，少阴脉所行，刺三分。内踝之后，筑宾穴，阴维之 ，刺三分，灸五壮。
少阴之前，阴维之会，以三脉会在此穴位分也。刺三分，灸五壮。今中诰经文正同此法。按∶甲乙经足太阳之
络别走少阴者，名曰飞扬，在外踝上七寸。又云筑宾阴维之 ，在内踝上 分中。复溜穴在内踝上二寸。今此
经注都与甲乙经不合者，疑经注中五寸字当作二寸，则素问与甲乙相应矣。）昌阳之脉令人腰痛，痛引膺，目
KTKT 然，甚则反折，舌卷不能言。（阴跷脉也。阴跷者，足少阴之别也，起于然骨之后，上内踝之上，直
上循阴股入阴，而循腹上入胸里，入缺盆，上出人迎之前，入 内廉，属目内 ，会于太阳阳跷而上行，故腰
痛之状如此。）刺内筋为二 ，在内踝上，大筋前，太阴后，上踝二寸所。（内筋谓大筋之前分肉也。太阴后，
大筋前，即阴跷之 ，交信穴也。在内踝上二寸，少阴前，太阴后，筋骨之间，陷者之中。
刺四分，留五呼，灸三壮。）散脉令人腰痛而热，热甚生烦，腰下如有横木居其中，甚则遗溲。（散脉，足太
阴之别也，散行而上，故以名焉。其脉循股内，入腹中，与少阴少阳结于腰髁下骨空中，故病则腰下如有横
木居其中，甚乃遗溲也。）刺散脉在膝前骨肉分间，络外廉束脉，为三 。（谓膝前内侧也。骨肉分谓膝内辅
骨之下，下廉 肉之两间也。络外廉则太阴之络，色青而见者也。辅骨之下，后有大筋撷束膝 之骨，令其连
属，取此筋骨系束之处脉以去其病，是曰地机，三刺而已，故曰束脉为之三 也。）肉里之脉令人腰痛，不可
以咳，咳则筋束急。（肉里之脉，少阳所生，则阳维之脉气所发也。里，里也。）刺肉里之脉为二 ，在太阳
之外，少阳绝骨之后。分肉主之。一经云少阳绝骨之前，传写误也。绝骨之前，足少阳脉所行，绝骨之后，
阳维脉所过，故指曰在太阳之外，少阳绝骨之后也。分肉穴，在足外踝直上绝骨之端如后二分，筋肉分间，阳
维脉气所发。刺五分，留十呼，灸三壮。（按∶新校正云∶“分肉之穴，甲乙经不见，与气穴注两出而分寸不同。
气穴注二分作三分，五分作三分，十呼作七呼。”）腰痛挟脊而痛至头，KT KT 然，目KT KT 然欲僵仆，
刺足太阴 中出血。（ 中，委中。按∶新校正云∶“太素作头沉沉然。”KT 音殊，鸟短羽也。）腰痛上寒，
刺足太阳阳明；上热，刺足厥阴；不可以俯仰，刺足少阳；中热而喘，刺足少阴，刺 中出血。（此法玄妙，中
诰不同，莫可窥测，当用知其应不尔，皆应先去血络乃调之也。）腰痛上寒不可顾，刺足阳明；（上寒，阴市
主之。阴市在膝上三寸，伏兔下陷者中，足阳明脉气所发。刺三分，留七呼，灸三壮。不可顾，三里主之。三
里在膝下三寸， 外廉，两筋肉分间，足阳明脉之所入也。刺一寸，留七呼，灸三壮。）上热，刺足太阴；（
地机主之。地机在膝下五寸，足太阴之 也。刺三分，灸三壮。）中热而喘，刺足少阴。（涌泉、
大钟悉主之。涌泉在足心陷者中，屈足卷指宛宛中，足少阴脉之所出。刺三分，留三呼，灸三壮。大钟在足跟
后冲中动脉，足少阴之络。刺二分，留七呼，灸三壮。按∶新校正云∶“刺疟注大钟在内踝后冲中，水穴论注
在内踝后，此注在跟后冲中动脉，三注不同。甲乙经亦云跟后冲中，当从甲乙经为正。”）大便难，刺足少阴。（
涌泉主之。）少腹满，刺足厥阴。（太冲主之。在足大趾本节后内间二寸，陷者中，动脉应手，足厥阴脉之所
注也。刺三分，留十呼，灸三壮。）如折，不可以俯仰，不可举，刺足太阳。（如折，束骨主之。不可以俯仰，
京骨、昆仑悉主之。不可举，申脉、仆参悉主之。束骨在足小趾外侧本节后，赤白肉际陷者中，足太阳脉之所
注也。刺三分，留三呼，灸三壮。京骨在足外侧大骨下，赤白肉际陷者中，按而得之，足太阳脉之所过也。刺
三分，留七呼，灸三壮。昆仑在足外踝后跟骨上，陷者中，细脉动应手，足太阳脉之所行也。刺五分，留十呼，
灸三壮。申脉在外踝下五分，容爪甲，阳跷之所生也。刺六分，留十呼，灸三壮。仆参在跟骨下陷者中，细脉
动应手，足太阳阳跷二脉之会。刺三分，留七呼，灸三壮。按∶新校正云∶“甲乙经申脉在外踝下陷者中，无
五分字，刺入六分作三分，留十呼作六呼，气穴注作七呼。仆参留七呼，甲乙经作六呼。”）引脊内廉，刺足
人体全身，屈伸俯仰，都依赖腰部，所以患病时多表现为疼痛。从足太阳经到奇经别络等引起腰痛的，有的是经脉所经过的部位，有的是络脉所系属的部位，有的是血脉所通行的部位，世人认为腰痛全都属于肝肾病变，这是错误的。
足太阳经脉使人腰痛，疼痛牵引项部、脊背和尻部，感觉像背负重物一样。（足太阳经脉，分支下行至项部，沿肩胛内侧，夹脊柱抵达腰中，分支下行贯穿臀部，所以使人出现上述病症。按：新校正说：“《甲乙经》中‘贯臀’作‘贯胂’，《刺疟论》注中也作‘贯胂’，《三部九候论》注中作‘贯臀’。”）针刺足太阳正经出血，春季不要见血。（“中”指委中穴（Weizhong, BL40），位于膝后腘窝横纹中央的动脉处，是足太阳经脉气血深入的地方。针刺深度五分，留针七次呼吸的时间，艾灸三壮。足太阳与肾相表里，肾气旺于冬季，水气衰于春季，所以春季不要放血。）少阳经脉使人腰痛，痛感像针刺在皮肤中，隐隐作痛，不能俯仰，也不能回头看。足少阳经脉，绕耳后，横向进入髋关节中，所以导致腰痛，痛感像针刺在皮肤中，隐隐作痛，不能俯仰。足少阳胆经，起于目外眦，向上到达头角，向下经过耳后，沿颈部行走，在手阳明经之前，至肩部，交叉出手少阳经之后。其分支，从目外眦下行至大迎穴，与手少阳经在下关穴会合，加于颊车穴，下行颈部，与缺盆会合。所以不能回头看。按：新校正说：“《甲乙经》中‘行手阳明之前’，作‘行手少阳之前’。”针刺足少阳成骨端出血，成骨位于膝盖外侧突起独高的骨头，夏季不要见血。（成骨是指膝外侧近下方，腓骨上端，两骨并排之间，凹陷能容纳手指的地方。腓骨构成支撑膝和大腿骨的柱子，所以称为成骨。足少阳与肝相表里，肝气旺于春季，木气衰于夏季，所以夏季不要放血。）阳明经脉使人腰痛，不能回头看，回头看时好像看到了幻象，容易悲伤。（足阳明胃经，起于鼻翼旁交于鼻根中，向下沿鼻外侧，进入上齿中，回转出来夹口环绕嘴唇，向下交会于承浆穴，然后沿下颌后下缘，出大迎穴。其分支，从大迎穴前，下行至人迎穴，沿喉咙，入缺盆。又一支分支，起于胃的下口，沿腹内，至气街中会合后下行至大腿，所以使人腰痛不能回头看，回头看时好像看到了幻象。阳气虚，所以悲伤。）针刺足阳明经膝前三寸处的穴位，上下调和出血，秋季不要见血。（《内经》、《中诰流注图经》中，关于阳明经脉穴位的主治，这种腰痛，都应针刺膝前三寸处，那就是正三里穴（Zusanli, ST36）。足阳明与脾相表里，脾气旺于长夏，土气衰于秋季，所以秋季不要放血。按：新校正说：“《甲乙经》中‘犊鼻’作‘膝眼’。‘膝’音委。”）足少阴经脉使人腰痛，疼痛牵引脊骨内侧。（足少阴肾经，上行于大腿内侧后缘，贯穿脊柱连属于肾，所以使人腰痛，疼痛牵引脊骨内侧。按：新校正说：“全元起本中‘脊内廉’作‘脊内痛’，《太素》也相同。此前有足太阴腰痛证，并针刺足太阴的方法，应是古书脱简所致。”）针刺足少阴经在内踝上二寸处，春季不要见血，如果出血太多，就无法恢复了。（《内经》、《中诰流注图经》中，关于少阴经脉穴位的主治，这种腰痛，应当针刺内踝上方，那就是正复溜穴（Fuliu, KI7）。复溜穴在内踝后上方二寸，动脉凹陷处。针刺三分，留针三次呼吸的时间，艾灸五壮。）厥阴经脉使人腰痛，腰部中间像拉满弓弩的弦一样紧绷。（足厥阴肝经，自大腿内侧，环绕生殖器，抵少腹。其分支，与足太阴、足少阳结于腰髁下，夹脊柱第三、第四椎骨间的空隙，其穴位即中膂俞（Zhonglshu, BL27）、下髎（Xialiao, BL34）等。所以腰痛时腰部像拉满弓弩的弦一样。像张弦，是说强急得很厉害。）针刺厥阴经脉，在足跟鱼腹之外的地方，顺着摸到有结节累累的样子，就针刺它。（“踵”指脉在足外侧下方，正当足跟处。情势像卧着的鱼腹，所以叫鱼腹之外。顺着肌肉间隙有血络累累的样子，就针刺它。这正当蠡沟穴（Ligou, LR5）分界处，是足厥阴之络，在内踝上五寸，别走足少阳的。针刺二分，留针三次呼吸的时间，艾灸三壮。按：经文说厥阴之脉，注释说厥阴之络，新校正怀疑是经文错误，其实不是。大概“脉”是统称，可以兼指“络”，并非错误。）这种病使人沉默寡言，神志不清，针刺三次。（厥阴经脉，沿喉咙后方，上入颃颡，联络舌根，所以生病则善言。风邪盛则昏冒，所以神志不爽慧。针刺三次那个部位，腰痛才能消除。按：新校正说：“经文说‘善言默默然不慧’，‘善言’与‘默默’两种病状难以同时存在。全元起本没有‘善’字，从义理上讲更合理。”现在改为遵从它。“另外《甲乙经》中厥阴之脉不络舌本，王冰在《素问》五处篇引注，而注《厥论》、《刺热论》及此三篇都说络舌本，注《风论》、《痹论》两篇不说络舌本，大概王冰也怀疑而两存其说。”）解脉使人腰痛，疼痛牵引肩部，眼睛视物模糊，时常遗尿。（解脉，是散行的经脉，说不合于主干而别行。这是足太阳经，起于目内眦，上额交巅，上循肩膊，夹脊柱抵达腰中，入循膂肉，络肾，属膀胱，下行入腘中，所以出现这些病症。又其分支，从腘内别出下行贯穿胂肉，沿大腿外后侧而下，合于腘中。两条脉像解开股的绳子一样，所以名叫解脉。）针刺解脉在膝后筋肉分间腘外廉的横脉出血，血色变红就停止。（膝后两旁大筋双上股之后，两筋之间，横纹之处，努起的肉高起，就是腘中的分界。古《中诰》以腘中为太阳之郄。应当取腘外廉有血络横现，迢迢紫黑而盛满的，就针刺它，应当见到黑血，必须等到血色变赤才停止，血不变赤，极尽泻之，必须等到血色变赤才停止，这是太阳经郄中治疗腰痛的方法。）解脉使人腰痛像被带子牵引，常常像腰折断一样，容易恐惧。（足太阳之别脉，自肩部别出下行沿背脊，至腰部横向进入大腿外后侧，而下合于腘中，所以像被带子牵引像腰折断一样。按：新校正说：“《甲乙经》中‘如引带’作‘如裂’，‘善恐’作‘善怒’。”）针刺解脉在腘中结络如黍米大小的地方，针刺时黑血喷射而出，见到赤血就停止。（腘中就是委中穴，足太阳合穴，即膝后腘窝横纹中央约文中动脉。针刺五分，留针七次呼吸的时间，艾灸三壮，这是本经的刺法。现在是取其结络大如黍米的，应当黑血箭射而出，见到血变赤，才可以停止。按：新校正说：“全元起说：有两解脉，病源各异，恐怕有误，未详。”）同阴之脉使人腰痛，痛感像有小锤子住在其中，郁滞肿胀。足少阳之别络，并足少阳经上行，距足外踝上五寸，乃别走足厥阴，并经下行络足跗，所以叫同阴脉。怫，是怒的意思，说肿得像发怒一样。（按：新校正说：“《太素》中‘小锤’作‘小针’。”）针刺同阴之脉，在外踝上绝骨之端，针刺三次。（绝骨之端如前所述三分处，是阳辅穴（Yangfu, GB38），足少阳脉所行。针刺五分，留针七次呼吸的时间，艾灸三壮。）阳维之脉使人腰痛，痛处上部郁滞肿胀。（阳维起于阳跷，则是太阳经所生，奇经八脉，这是其中之一。）针刺阳维之脉，脉与太阳经合于腘下间，距地一尺左右。（太阳经所生，与正经并行而上，至腘下又与太阳经合而上行。腘下去地一尺，就是承光穴（Chengguang, BL9），在锐骨下肉分间，凹陷处。针刺七分，艾灸五壮。因为取的是锐骨下肉分间，所以说合于腘下间。按：新校正说：“穴所在的位置，乃是承山穴，不是承光穴。‘山’字误写为‘光’。”）衡络之脉使人腰痛，不能俯仰，仰则害怕跌倒，这是由于举重损伤腰部，衡络断绝，恶血归聚于此。（衡，通横，谓太阳之外络自腰中横向进入大腿外后侧而下与中经合于腘中的。如今举重重伤腰部，则横络断绝，中经独盛，所以腰痛不能俯仰了。一本作冲绝之脉，是传写时的鱼鲁之误。如果是冲脉，《中诰》不应取太阳脉的委阳、殷门穴。）针刺在腘阳、筋肉之间、上方数寸横居的位置，设为两个穴位，出血。（横居二穴，指委阳（Weiyang,

The entire human body relies on the waist for flexion, extension, bending, and looking up or down; therefore, when diseased, it often manifests as pain. Those causing lower back pain from the Foot-Taiyang channel to the extraordinary meridians and collateral vessels—whether due to the path of the main channels, the attachment of the collaterals, or the passage of the vessels—are mistakenly considered by the world to belong entirely to the Liver and Kidney.
The Foot-Taiyang channel causes lower back pain, with pain radiating to the nape, spine, sacrum, and back, feeling as if bearing a heavy load. (The Foot-Taiyang channel has a branch descending to the nape, running along the medial aspect of the shoulder blade, flanking the spine to reach the middle of the waist, and another branch descending through the buttocks, thus causing the aforementioned symptoms. Note: The New Correction states that "Guan Tun" in the *Jia Yi Jing* is written as "Guan Shen"; the note in the *Ci Nu Lun* also writes "Guan Shen," while the note in the *San Bu Jiu Hou Lun* writes "Guan Tun".) Bleed the main channel of the Foot-Taiyang at its entry point, but do not bleed in Spring. ("Zhong" refers to Weizhong (BL40), located in the center of the popliteal crease where the artery beats, which is the entry point of the Foot-Taiyang channel. Needle depth: 5 fen; retain for seven breaths; moxa: 3 zhu. The Foot-Taiyang corresponds to the Kidney; Kidney Qi prospers in Winter, and Water Qi declines in Spring; hence, no bleeding in Spring.) The Shaoyang channel causes lower back pain, with a sensation like needles pricking the skin, lingering pain preventing flexion and extension, and inability to look back. The Foot-Shaoyang channel winds around the ear, enters horizontally into the hip joint, thus causing lower back pain with a sensation like needles pricking the skin, lingering pain preventing flexion and extension. The Gallbladder channel of the Foot-Shaoyang originates at the outer canthus, ascends to the frontal angle, descends behind the ear, runs along the neck anterior to the Hand-Yangming channel, reaches the shoulder, and crosses posterior to the Hand-Shaoyang channel. Its branch descends from the outer canthus to Daying, meets the Hand-Shaoyang at Xiaguan, passes through Jiache, descends the neck, and meets at the collarbone. Hence, one cannot look back. Note: The New Correction states that "Xing Shou Yangming Zhi Qian" in the *Jia Yi Jing* is written as "Xing Shou Shaoyang Zhi Qian." Bleed the end of the Chenggu bone of the Shaoyang; Chenggu is the solitary prominent bone on the lateral side of the knee. Do not bleed in Summer. (Chenggu refers to the upper end of the fibula near the lateral knee, between the two rising bones where a depression fits a finger. The fibula forms the pillar supporting the knee and thigh bones, hence called Chenggu. The Shaoyang corresponds to the Liver; Liver Qi prospers in Spring, and Wood Qi declines in Summer; hence, no bleeding in Summer.) The Yangming channel causes lower back pain with inability to look back; when looking back, one may see phantoms and feel prone to sadness. (The Foot-Yangming channel originates beside the nose, crosses the nasal root, descends along the lateral nose, enters the upper teeth, returns to encircle the lips, meets at Chengjiang, then follows the mandible posteriorly to Daying. Its branch descends from Daying to Renying, runs along the throat, and enters the clavicle. Another branch originates from the lower opening of the stomach, runs within the abdomen, meets at Qichong, and descends to the thigh, thus causing lower back pain with inability to look back and visual disturbances. Yang deficiency leads to sadness.) Bleed the three points anterior to the knee on the Yangming channel, harmonizing above and below, but do not bleed in Autumn. (In the *Nei Jing* and *Zhong Gao Liu Zhu Tu Jing*, regarding the indications for Yangming acupoints, this type of lower back pain should be treated by needling the point three cun anterior to the knee, which is Zusanli (ST36). The Yangming corresponds to the Spleen; Spleen Qi prospers in Late Summer, and Earth Qi declines in Autumn; hence, no bleeding in Autumn. Note: The New Correction states that "Du Bi" in the *Jia Yi Jing* is written as "Xi Yan." 'Xi' sounds like 'Wei'.) The Foot-Shaoyin channel causes lower back pain, with pain radiating to the medial aspect of the spine. (The Foot-Shaoyin channel ascends along the posterior medial aspect of the thigh, penetrates the spine, and connects to the Kidney, thus causing lower back pain radiating to the medial spine. Note: The New Correction states that in Quan Yuanqi's edition and the *Tai Su*, "Ji Nei Lian" is written as "Ji Nei Tong." This suggests a missing slip in the ancient text regarding Taiyin lower back pain and its treatment methods.) Bleed the Foot-Shaoyin at two cun above the medial malleolus, but do not bleed in Spring; excessive bleeding cannot be restored. (In the *Nei Jing* and *Zhong Gao Liu Zhu Tu Jing*, regarding the indications for Shaoyin acupoints, this lower back pain should be treated by needling above the medial malleolus, specifically Fuliu (KI7). Fuliu is located two cun posterior-superior to the medial malleolus in the arterial depression. Needle depth: 3 fen; retain for three breaths; moxa: 5 zhu.) The Jueyin channel causes lower back pain, with the waist feeling tight like a drawn bowstring. (The Foot-Jueyin channel originates from the inner thigh, circles the genitalia, and reaches the lower abdomen. Its branch connects with the Taiyin and Shaoyang below the hip, flanking the third and fourth lumbar vertebrae spaces, where acupoints such as Zhongshu (BL27) and Xialiao (BL34) are located. Thus, lower back pain feels like a drawn bowstring. "Like a drawn string" indicates extreme stiffness.) Needle the Jueyin channel where it is outside the fish-belly area of the heel; follow until nodules are felt, then needle. ("Zhong" refers to the pulse location on the lateral side of the foot near the heel. The contour resembles the belly of a lying fish, hence "outside the fish-belly." Follow the muscle intervals until blood vessels appear nodular, then needle. This corresponds to Ligou (LR5), the Luo-connecting vessel of the Foot-Jueyin, five cun above the medial malleolus, diverging to the Shaoyang. Needle depth: 2 fen; retain for three breaths; moxa: 3 zhu. Note: The text mentions the Jueyin channel, while the commentary mentions the Jueyin Luo; the New Correction doubts this is an error, but it is not. "Channel" is a general term that can include "Luo," so it is not an error.) This disease causes silence and mental confusion; needle three times. (The Jueyin channel runs posterior to the throat, enters the nasopharynx, and connects to the base of the tongue, thus causing excessive talking when diseased. Wind excess causes dizziness and confusion, leading to lack of clarity. Needling this area three times eliminates the lower back pain. Note: The New Correction states that "Shan Yan Mo Mo Ran Bu Hui" contains contradictory symptoms ("excessive talking" vs. "silence"). Quan Yuanqi's edition omits "Shan," which is more logical. We adopt this correction. Additionally, the *Jia Yi Jing* states the Jueyin channel does not connect to the tongue base. Wang Bing notes this in several chapters but omits it in others, showing his own doubt.) The Xie Mai (Loose Channel) causes lower back pain radiating to the shoulder, blurred vision, and occasional urinary incontinence. (Xie Mai refers to scattered channels that run separately from the main trunk. This is the Foot-Taiyang channel, originating at the inner canthus, crossing the vertex, ascending along the shoulder blades, flanking the spine to the waist, entering the erector spinae, connecting to the Kidney, belonging to the Bladder, and descending into the popliteal fossa, thus causing these symptoms. Another branch diverges from the popliteal fossa, passes through the hamstring, runs along the posterolateral thigh, and joins the popliteal fossa. The two vessels resemble unbound thighs, hence named Xie Mai.) Bleed the horizontal vessel on the lateral aspect of the popliteal fossa between the muscle and tendon divisions of the knee; stop when the blood color changes. (This refers to the large tendons on both sides of the back of the knee, the space between them posterior to the thighs, and the transverse lines. Where the flesh protrudes is the boundary of the popliteal fossa. Ancient texts identify the popliteal fossa as the Xi-Cleft point of the Taiyang. Select the horizontal blood vessel visible on the lateral aspect of the popliteal fossa, which appears dark purple and full, and needle it. Black blood will emerge; wait until the blood turns red before stopping. If the blood does not turn red, drain thoroughly until it turns red. This is the method for treating Taiyang Xi-Clower back pain.) Xie Mai causes lower back pain as if pulled by a belt, often feeling like the waist is broken, with frequent fear. (The collateral branch of the Foot-Taiyang diverges from the shoulder, descends along the spine, enters the hip laterally at the waist, and joins the popliteal fossa, thus feeling like being pulled by a belt or having a broken waist. Note: The New Correction states that "Ru Yin Dai" in the *Jia Yi Jing* is written as "Ru Lie," and "Shan Kong" is written as "Shan Nu.") Needle the Xie Mai at the nodules in the popliteal fossa the size of millet grains; when black blood shoots out, stop when red blood appears. (The popliteal fossa is Weizhong (BL40), the He-Sea point of the Foot-Taiyang, located in the center of the popliteal crease. Needle depth: 5 fen; retain for seven breaths; moxa: 3 zhu. This is the standard needling method for this channel. Here, we target the nodule the size of millet grains; when black blood shoots out, stop when the blood turns red. Note: The New Correction states that Quan Yuanqi mentions two Xie Mails with different pathological origins, suggesting possible error, but details are unclear.) The Tongyin Mai causes lower back pain with a sensation like a small hammer lodged inside, accompanied by distending swelling. (This is the collateral branch of the Foot-Shaoyang, ascending with the Foot-Shaoyang channel, five cun above the lateral malleolus, where it diverges to the Jueyin, descends, and connects to the dorsum of the foot, hence called Tongyin Mai. "Fu" means anger/swelling, indicating swelling as if angry. Note: The New Correction states that "Xiao Chui" in the *Tai Su* is written as "Xiao Zhen.") Needle the Tongyin Mai at the end of the Juegu bone above the lateral malleolus, three times. (The end of Juegu is three cun as described previously, corresponding to Yangfu (GB38), where the Foot-Shaoyang channel travels. Needle depth: 5 fen; retain for seven breaths; moxa: 3 zhu.) The Yangwei Mai causes lower back pain with distending swelling in the upper part. (Yangwei originates from Yangqiao, generated by the Taiyang; it is one of the Eight Extraordinary Vessels.) Needle the Yangwei Mai where the vessel merges with the Taiyang below the popliteal fossa, about one chi from the ground. (Generated by the Taiyang, it runs parallel to the regular channels upward, merging again with the Taiyang below the popliteal fossa. One chi below the popliteal fossa is Chengguang (BL9), located in the depression between the muscles below the sharp bone. Needle depth: 7 fen; moxa: 5 zhu. Because it targets the muscle interval below the sharp bone, it is said to merge below the popliteal fossa. Note: The New Correction states that the acupoint is actually Chengshan, not Chengguang; "Shan" was miswritten as "Guang".) The Hengluo Mai causes lower back pain preventing flexion and extension; extending the back causes fear of falling. This results from lifting heavy objects injuring the waist, severing the Hengluo, causing evil blood to accumulate. ("Heng" means transverse; referring to the external collateral of the Taiyang that enters horizontally from the waist into the posterolateral thigh and joins the main channel in the popliteal fossa. Heavy lifting injures the waist, severing the transverse collateral, causing the main channel to become hyperactive, leading to lower back pain preventing flexion and extension. One version reads "Chongjue," which is a transcription error. If it were the Chong Mai, the *Zhong Gao* would not select Weiyang and Yinmen of the Taiyang channel.) Needle at Weiyang and between the tendons, horizontally positioned several cun above, using two points, and bleed. (The two horizontally positioned points are Weiyang (BL39) and Yinmen (BL37), aligned horizontally. Weiyang is lateral to the Fuxi point. The space between tendons refers to the space between the two tendons in the popliteal fossa, where Yinmen is located. Both points are six cun above the transverse line of the buttock, hence "several cun above the popliteal fossa." Weiyang: needle 7 fen, retain 5 breaths, moxa 3 zhu. Yinmen: needle 5 fen, retain 7 breaths, moxa 3 zhu. Hence, "horizontally positioned as two points." Note: The New Correction states that Wang Bing's description of Weiyang being superior to Fuxi contradicts the *Jia Yi Jing*, which places Weiyang one cun inferior to Fuxi.) The Huiyin Mai causes lower back pain, profuse sweating on the upper body, thirst after sweat dries, and restlessness after drinking. (This is the main channel of the Foot-Taiyang. Its vessel runs along the waist and converges at the posterior orifice, hence called Huiyin Mai. The channel descends from the waist to the foot; currently, Yang Qi is excessively abundant, causing pain and profuse sweating. After sweating, Kidney fluid becomes dry and Yin deficient, causing thirst to save the Kidney. After drinking, Kidney Qi recovers, Yin flows, and Taiyang becomes abundant again, causing restlessness. Note: "Tuo" is pronounced "He," describing the appearance of sweating.) Needle the Zhiyang Mai three times above, horizontally positioned five cun below the popliteal fossa on the Yangqiao, bleeding where vessels are full. (The Zhiyang Mai is the Taiyang channel, descending flanking the spine through the buttocks to the popliteal fossa, then down the calf, passing behind the lateral malleolus, running straight, hence called Zhiyang Mai. Yangqiao originates at Shenmai (BL62), below the lateral malleolus. "Below the popliteal fossa" refers to the area five cun below the popliteal fossa, connecting the point above the popliteal fossa and below Shenmai, which is Chengjin (BL57), located in the depression in the center of the calf, where Taiyang Qi emerges. Needling is prohibited here; moxa 3 zhu. The instruction to needle refers to bleeding the full blood vessels. Both calves have descending Taiyang Qi; observe the central blood vessels in both calves for fullness and bleed. Hence, "bleed where vessels are full." Note: The New Correction states that although the text mentions Huiyin Mai causing lower back pain and then instructs needling Zhiyang Mai, they refer to the same phenomenon with different wording. Also, the note for Chengjin says "center of the calf like an outward depression," but the *Jia Yi Jing* and *Gu Kong Lun* notes omit "like an outward depression".) The Feiyang Mai causes lower back pain with distending discomfort, progressing to sadness and fear. (This is the Yinwei Mai, five cun above the medial malleolus in the calf division, ascending with the Shaoyin channel. Anterior to the Shaoyin channel is the path of the Yinwei Mai. The Foot-Shaoyin channel ascends from the Kidney through the Liver and diaphragm, enters the Lung, runs along the throat, and flanks the tongue base. Its branch exits the Lung, connects to the Heart, and pours into the chest. Hence, severe cases involve sadness and fear. Fear originates in the Kidney, sadness in the Heart. Note: Sadness is the emotion of the Lung; the commentary stating it originates in the Heart is incorrect.) Needle the Feiyang Mai five cun above the medial malleolus, (Note: *Jia Yi Jing* says two cun.) anterior to the Shaoyin, meeting the Yinwei. (Five cun posterior-superior to the medial malleolus is Fuliu (KI7), where the Shaoyin channel travels; needle 3 fen. Posterior to the medial malleolus is Zhubin (KI9), the Xi-Cleft of the Yinwei; needle 3 fen, moxa 5 zhu. Anterior to the Shaoyin is the meeting of the Yinwei, where three vessels converge. Needle 3 fen, moxa 5 zhu. The current *Zhong Gao* text matches this method. Note: The *Jia Yi Jing* states the collateral of the Foot-Taiyang diverging to the Shaoyin is named Feiyang, seven cun above the lateral malleolus. It also states Zhubin is the Xi-Cleft of the Yinwei, in the calf division above the medial malleolus. Fuliu is two cun above the medial malleolus. The discrepancy between this commentary and the *Jia Yi Jing* suggests the "five cun" in the text should be "two cun" to align with the *Jia Yi Jing*.) The Changyang Mai causes lower back pain radiating to the chest, blurred vision, severe opisthotonos, tongue rolling, and inability to speak. (This is the Yinqiao Mai. The Yinqiao is a branch of the Foot-Shaoyin, originating behind Ran Gu, ascending above the medial malleolus, running straight up the inner thigh into the genitalia, then along the abdomen into the chest, entering the clavicle, ascending anterior to Renying, entering the nasopharynx, connecting to the inner canthus, and meeting the Taiyang and Yangqiao to ascend, thus causing these lower back pain symptoms.) Needle two points at Neijin, above the medial malleolus, anterior to the large tendon, posterior to the Taiyin, approximately two cun above the ankle. (Neijin refers to the muscle interval anterior to the large tendon. Posterior to the Taiyin and anterior to the large tendon is the Xi-Cleft of the Yinqiao, Jiaoxin (KI8). Located two cun above the medial malleolus, anterior to the Shaoyin, posterior to the Taiyin, in the depression between bone and tendon. Needle depth: 4 fen; retain for five breaths; moxa: 3 zhu.) The San Mai causes lower back pain with heat, severe heat causing irritability, a sensation of a horizontal wood block in the lower waist, and severe cases involving urinary incontinence. (San Mai is the collateral branch of the Foot-Taiyin, scattering upward, hence the name. Its vessel runs along the inner thigh, enters the abdomen, and connects with the Shaoyin and Shaoyang below the hip in the bony space, thus causing the sensation of a horizontal block in the lower waist and incontinence in severe cases.) Needle the San Mai in the muscle-bone division anterior to the knee, at the lateral aspect of the collateral vessels, using three points. (Refers to the medial anterior knee. Muscle-bone division refers to the space between the muscles below the medial condyle. The lateral collateral is the Taiyin collateral, appearing blue-green. Below the condyle, a large tendon binds the patella; take the pulse at this binding site to treat the disease, known as Diji (SP8). Three needleings suffice, hence "binding vessels with three needleings".) The Rouli Mai causes lower back pain preventing coughing; coughing causes tendon spasms. (The Rouli Mai is generated by the Shaoyang and is where the Qi of the Yangwei Mai emerges. "Li" refers to the calf.) Needle two points of the Rouli Mai, lateral to the Taiyang, posterior to the Juegu of the Shaoyang. Fenrou governs this. One version says "anterior to Juegu," which is a transcription error. Anterior to Juegu is the path of the Foot-Shaoyang; posterior to Juegu is the path of the Yangwei Mai, hence specified as lateral to Taiyang and posterior to Shaoyang Juegu. Fenrou acupoint is two fen posterior to the end of Juegu directly above the lateral malleolus, in the muscle-tendon interval, where Yangwei Qi emerges. Needle depth: 5 fen; retain for ten breaths; moxa: 3 zhu. (Note: The New Correction states that Fenrou is not found in the *Jia Yi Jing*; measurements differ from the *Qi Xue* note. In *Qi Xue*, 2 fen is 3 fen, 5 fen is 3 fen, and 10 breaths is 7 breaths.) Lower back pain flanking the spine radiating to the head, heaviness in the head, blurred vision, and desire to collapse; bleed the popliteal fossa of the Foot-Taiyin. (Popliteal fossa is Weizhong. Note: The New Correction states that the *Tai Su* reads "head heavy." 'KT' sounds like 'Shu', meaning short-winged bird.) Upper cold in lower back pain: needle Foot-Taiyang and Yangming; upper heat: needle Foot-Jueyin; inability to flex/extend: needle Foot-Shaoyang; internal heat with panting: needle Foot-Shaoyin, bleed popliteal fossa. (This method is profound and differs from the *Zhong Gao*, making it hard to fathom. One must understand the correspondences; otherwise, one should first remove blood stasis before regulating.) Upper cold in lower back pain with inability to look back: needle Foot-Yangming. (Upper cold: governed by Yinshi (ST33). Yinshi is three cun above the knee, in the depression below Futu, where Yangming Qi emerges. Needle 3 fen, retain 7 breaths, moxa 3 zhu. Inability to look back: governed by Zusanli (ST36). Zusanli is three cun below the knee, on the lateral aspect of the tibia, between the two muscle bellies, where Yangming Qi enters. Needle 1 cun, retain 7 breaths, moxa 3 zhu.) Upper heat: needle Foot-Taiyin. (Governed by Diji (SP8). Diji is five cun below the knee, the Xi-Cleft of the Foot-Taiyin. Needle 3 fen, moxa 3 zhu.) Internal heat with panting: needle Foot-Shaoyin. (Governed by Yongquan (KI1) and Dazhong (KI4). Yongquan is in the depression at the center of the sole, when the foot is curled; it is the Jing-River point of the Foot-Shaoyin. Needle 3 fen, retain 3 breaths, moxa 3 zhu. Dazhong is at the pulsating artery behind the heel, the Luo-connecting vessel of the Foot-Shaoyin. Needle 2 fen, retain 7 breaths, moxa 3 zhu. Note: The New Correction states that the *Ci Nu Lun* note places Dazhong posterior to the medial malleolus, the *Shui Xue Lun* note places it posterior to the medial malleolus, and this note places it at the pulsating artery behind the heel. The three notes differ. The *Jia Yi Jing* also says "behind the heel at the pulsating artery," so follow the *Jia Yi Jing* as correct.) Difficulty defecating: needle Foot-Shaoyin. (Governed by Yongquan (KI1).) Fullness in the lower abdomen: needle Foot-Jueyin. (Governed by Taichong (LR3). Located two cun medial to the proximal interphalangeal joint of the big toe, in the depression where the artery beats; it is the Ying-Spring point of the Foot-Jueyin. Needle 3 fen, retain 10 breaths, moxa 3 zhu.) Feeling like breaking, inability to flex/extend, inability to lift: needle Foot-Taiyang. (Feeling like breaking: governed by Shugu (BL65). Inability to flex/extend: governed by Jinggu (BL64) and Kunlun (BL60). Inability to lift: governed by Shenmai (BL62) and Pucan (BL61). Shugu is in the depression at the red-white flesh junction posterior to the metatarsophalangeal joint of the little toe, the Ying-Spring point of the Foot-Taiyang.
