足太阳膀胱经的经脉，起始于目内眦（内眦指眼睛的大眼角），向上经过额部，交会于头顶（即巅顶。头顶中央有旋毛，可容纳豆子，此处称为三阳五会穴）。它的分支，从头顶行至耳上角。其直行者，从头顶入里联络脑部（头顶正中前部叫囟顶，后部叫脑顶，左右两侧叫角），复出并向下行于项部，沿肩膊内侧，夹脊柱抵达腰中，入里联络肾脏（肾是膀胱的维系，所以膀胱脉络系于肾），归属于膀胱（足太阳经是膀胱的经脉，所以其脉归属于膀胱）。它的另一分支，从腰中部分出，向下贯穿臀部，进入腘窝中（腘窝指膝后弯曲处的委中穴）。又一支脉，从肩膊内侧左右分别下行，贯穿肩胛（肩胛部位在两髀骨之下，肾脏竖起的肌肉处），夹脊柱内侧，经过髀枢（环跳穴位于此髀枢之中，《素问》说：髀枢中络正者，正指的就是这里），沿大腿外侧，从后侧下行与腘窝中的支脉汇合，由此向下穿过小腿肚（腨）内侧，出于外踝后方（外踝后方是昆仑穴所在之处），沿京骨穴（京骨是穴位名，为足太阳经的原穴，位于足外侧大骨下方），到达小趾外侧端（小趾外侧端是至阴穴的分界处。《素问》说：足太阳经的井穴起于至阴。足太阳经从此处交入足少阴经）。
当足太阳经发生变动时，会出现病症（足太阳经通常多血少气，现在气先发病，这叫做“是动”病）。症状包括：冲头痛，眼睛感觉像要脱出，颈部感觉像被拔起，脊痛腰痛好像要折断，大腿不能弯曲，小腿肚像被捆结一样僵硬，又像撕裂般疼痛，这叫做“踝厥”。本经主治筋所生的疾病（血受气的影响而生病，这是气所生发的，所以叫“所生病”。足太阳经血多气少，这是人体的常数。也有不同于常数的情况，《灵枢经》说：足太阳经上部气血旺盛，则眉毛美丽且有毫毛；血少气多则恶血多、气少；血少气多则浮肿、纹理细密；血少气多则肉多而血涩；气血调和则面色美好。足太阳经下部，气血旺盛则脚跟肌肉丰满，若踵以上气少血多则脚跟消瘦空虚；气血皆少则容易转筋，脚跟下疼痛。由此可见，足太阳经多血，通过观察足太阳经气血的多少，可以了解这些情况）。此外还治疗痔疮、疟疾、狂证、巅顶疾病（《素问》说：所谓狂证和巅顶疾病，是因为阳气尽在上部，而阴气从下部上升）。症状还包括：头囟顶部疼痛，目黄流泪，鼻塞流涕或鼻出血，颈背腰尻及小腿肚脚部都疼痛，小趾不能活动（足太阳经行于身体背部阳面，所以头脑、项背、腰尻、小腿肚、脚都疼痛，小趾也不能活动）。脉象方面，邪气盛的人迎脉比寸口脉大二倍；正气虚的人迎脉反而小于寸口脉。
足太阳经的别络，名叫飞阳，距离外踝七寸，别走足少阴经。实证表现为鼻塞不通，头背痛；虚证表现为鼻塞流涕或鼻出血。治疗取该别络分出的穴位。
足太阳经的筋，起始于足小趾，向上结聚于踝部，斜向上结聚于膝部。其下行部分沿足外侧结聚于脚跟，向上沿跟腱结聚于腘窝。其分支，结聚于腘窝外侧，上行至腘窝内侧廉，在腘窝中汇合，并向上结聚于臀部，向上夹脊柱上行至项部。其分支，别入结聚于舌根。其直行者，结聚于枕骨，上头下行至颜面结聚于鼻。其分支，成为眼睑的上纲，向下结聚于目内眦。其分支，从腋后外侧结聚于肩髃。其分支，进入腋下，向上出于缺盆，向上结聚于完骨。其分支，出于缺盆，斜向上出于风府。这些筋的病证，表现为小趾及脚跟肿痛，腘窝挛急导致脊柱反折，项部筋脉拘急，肩部不能举起，腋部支撑感且缺盆中牵拉疼痛，不能左右摇摆。治疗采用燔针劫刺的方法，以病情好转为度，以痛点作为腧穴。这种病名叫仲春痹。
邪气客居于足太阳经的络脉，使人头项肩痛。针刺足小趾爪甲上的至阴穴，以及趾肉交接处各一壮，立即痊愈。如果未愈，针刺外踝下三寸处，左病刺右，右病刺左，大约吃一顿饭的时间，病就好了。邪气客居于足太阳经的络脉，使人拘挛背急，两胁牵引疼痛。针刺应从项部开始，数脊椎，夹脊病变处取穴，按压穴位感到疼痛的地方进行针刺，针刺三壮，立即痊愈。

The meridian of Foot-Taiyang (Bladder) originates at the inner canthus (the medial corner of the eye), ascends to the forehead, and intersects at the vertex (Dingchuan). The vertex is the top of the head; in the center of the vertex, there is a whorl of hair where a bean can be placed, known as the meeting point of the three Yang meridians and five Hui acupoints. Its branch travels from the vertex to the supraorbital ridge. The straight branch enters the brain from the vertex (the anterior part of the vertex is called Xiding, the posterior part Naoding, and the lateral parts Jiao), emerges again, descends separately to the nape, follows the medial aspect of the shoulder blade, flanks the spine, reaches the middle of the waist, enters internally to connect with the Kidney (the Kidney serves as the support for the Bladder, thus the Bladder meridian connects with the Kidney), and belongs to the Bladder (Foot-Taiyang is the meridian of the Bladder, hence its vessel belongs to the Bladder). Another branch arises from the middle of the waist, descends through the buttocks, and enters the popliteal fossa (the popliteal fossa refers to the crease behind the knee, where Weizhong BL-40 is located). Another branch descends separately from the medial aspect of the shoulder blade on both sides, passes through the scapula (the scapular region is below the lower ends of the humerus, corresponding to the muscles arising from the kidneys), flanks the spine internally, passes through the hip pivot (Huantiao GB-30 is located in this hip pivot; *Suwen* states: "The one connecting to the correct path in the hip pivot" refers to this), follows the lateral aspect of the thigh, descends along the posterior margin, and joins with the branch in the popliteal fossa. It then descends through the medial aspect of the calf muscle (Shuan), emerges posterior to the lateral malleolus (posterior to the lateral malleolus is where Kunlun BL-60 resides), follows Jinggu BL-64 (Jinggu is an acupoint name, the Yuan-Source point of Foot-Taiyang, located below the large bone on the lateral side), and reaches the lateral side of the little toe (the lateral side of the little toe is the division of Zhiyin BL-67. *Suwen* says: "The root of Foot-Taiyang starts at Zhiyin." Foot-Taiyang intersects with Foot-Shaoyin here).
When Foot-Taiyang undergoes change, disease occurs (Foot-Taiyang typically has abundant blood and scarce Qi; now that Qi is diseased first, this is called "Shidong" [moving] disease). Symptoms include: headache striking upward, eyes feeling as if they are falling out, neck feeling as if being pulled, back pain and waist pain as if breaking, inability to flex the thigh, stiffness in the calf as if bound, and tearing pain in the calf, which is called "Huajue" (Ankle Reversal). This meridian governs diseases generated by tendons (Blood becomes diseased due to Qi; since it is generated by Qi, it is called "Suoshengbing" [generated disease]. Foot-Taiyang has abundant blood and scarce Qi, which is the constant state of humans. However, there are exceptions. *Lingshu* states: When Qi and Blood are abundant in the upper part of Foot-Taiyang, eyebrows are beautiful and fine hairs grow; when blood is scarce and Qi is abundant, there is much evil blood and little Qi; when blood is scarce and Qi is abundant, there is edema and fine skin texture; when blood is scarce and Qi is abundant, flesh is abundant but blood flow is sluggish; when Qi and Blood are harmonious, the complexion is beautiful. In the lower part of Foot-Taiyang, when Qi and Blood are abundant, the heel flesh is full; if Qi is scarce and Blood is abundant above the heel, the heel is thin and empty; when both Qi and Blood are scarce, cramps occur easily, and there is pain below the heel. Thus, seeing beautiful eyebrows indicates that Foot-Taiyang has abundant blood. From this, the abundance or scarcity of Qi and Blood in Foot-Taiyang can be known.) It also treats hemorrhoids, malaria, mania, and vertex diseases (*Suwen* says: What is called mania and vertex disease is because Yang energy is exhausted in the upper part, while Yin energy rises from below). Symptoms also include: pain in the frontal fontanelle and vertex, yellow eyes with tearing, rhinorrhea or epistaxis, pain in the neck, back, waist, sacrum, calves, and feet, and dysfunction of the little toe (Foot-Taiyang runs along the Yang aspect of the body, hence pain in the head, brain, neck, back, waist, sacrum, calves, and feet, and dysfunction of the little toe). Regarding pulse diagnosis: when excess exists, the Renying (Carotid) pulse is twice as large as the Cunkou (Radial) pulse; when deficiency exists, the Renying pulse is smaller than the Cunkou pulse.
The Luo-Connecting vessel of Foot-Taiyang is named Feiyang BL-58. It is located seven cun above the ankle and diverges to connect with Shaoyin. In excess conditions, there is nasal obstruction and headache/back pain; in deficiency conditions, there is nasal discharge or epistaxis. Treatment involves selecting the point where it diverges.
The sinews of Foot-Taiyang originate from the little toe, ascend and bind at the ankle, slant upwards and bind at the knee. The descending part follows the lateral aspect of the foot and binds at the calcaneus, ascending along the Achilles tendon to bind at the popliteal fossa. Its branch binds at the lateral aspect of the popliteal fossa, ascends to the medial margin of the popliteal fossa, converges within the popliteal fossa, and ascends to bind at the buttock, continuing up along the spine to the nape. Its branch enters separately to bind at the base of the tongue. The straight branch binds at the occiput, ascends to the head, descends to the face, and binds at the nose. Its branch forms the upper eyelid margin and descends to bind at the inner canthus. Its branch arises from the posterior-lateral aspect of the axilla and binds at the shoulder joint. Its branch enters the axilla, ascends to emerge at the supraclavicular fossa, and binds at the mastoid process (Wangu). Its branch emerges from the supraclavicular fossa, slants upwards, and emerges at Fengfu GV-16. Diseases of these sinews present with swelling and pain in the little toe and calcaneus, spasms in the popliteal fossa causing opisthotonos, stiffness in the neck sinews, inability to raise the shoulder, support sensation in the axilla and pulling pain in the supraclavicular fossa, and inability to rotate left and right. Treatment employs burning needle (fire needle) rapid puncture, taking improvement as the criterion, and using painful points as acupoints. This condition is named Zhongchun Bi (Spring Midst Bi Syndrome).
When pathogenic factors invade the collateral vessels of Foot-Taiyang, they cause pain in the head, neck, and shoulder. Puncture Zhiyin BL-67 on the nail bed of the little toe, and the junction of nail and flesh, one moxa cone each. The disease will cease immediately. If not, puncture three cun below the lateral malleolus, treating the left side for right-sided symptoms and vice versa. After about the time it takes to eat a meal, the disease ceases. When pathogenic factors invade the collateral vessels of Foot-Taiyang, they cause spasms and stiffness in the back, with pulling pain in the hypochondrium. Puncture should start from the neck, counting the vertebrae, and select points flanking the spine where the disease is located. Press the area until tenderness is felt, then puncture beside it. Three moxa cones will cure it immediately.
The Foot-Taiyang Bladder Meridian runs from the head to the foot, measuring eight chi in length, totaling one zhang six chi for both sides. There are 126 acupoints in total.
