众痹（一种疼痛部位固定但交替发作的痹证）各自停留在其发生的部位。疼痛此处停止，彼处又发作；此处休止，彼处又起。右侧的症状与左侧相应，左侧的症状与右侧相应。这种病不能周身遍发，而是交替发作、交替休止。
（注：所谓“各在其处”，是指疼痛随邪气聚集之处而发作，不能遍及上下全身，只是或左或右，交替发作和休止，患病部位没有定所，所以称为众痹。）
治疗这种病，虽然疼痛已经停止，也必须针刺疼痛原发的部位，以防止它再次发作。（这是说必须针刺最初疼痛的部位。）
周痹（一种沿血脉上下移动、周身遍发的痹证），存在于血脉之中。随着经脉向上运行，也随着经脉向下运行，但不能像众痹那样左右分别对应其所在部位。（它能上能下，但随血脉在周身循环遍发，所以称为周痹。）
疼痛从上往下发展的，先针刺下部以阻断病势，后针刺上部以根除病源；疼痛从下往上发展的，先针刺上部以阻断病势，后针刺下部以根除病源。（“过”是去除病邪的意思，“之”指先去其标症；“脱”是拔绝病根的意思，指后去其本。）
这是因为风寒湿三气侵袭体表，客居于分肉（肌肉间隙）之间，逼迫津液凝结成沫。沫遇到寒气则凝聚，凝聚后就会排挤分肉导致分裂。分裂就会产生疼痛。（邪气客居肌表，逐渐进入分肉之间，逼迫津液变成汁沫。沫遇到寒气，就凝聚不散，从而排裂肌肉纹理产生疼痛。）
疼痛时，人的神志会集中于患处。神志集中于患处，局部就会发热。发热后疼痛暂时缓解。疼痛缓解后会出现气机逆乱（厥）。气机逆乱会导致其他部位的痹证发作，发作时就像这样。（疼痛时心神专注于该处，所以神归于此。神归即气归，气至则生热。热则寒散而疼痛暂时解除。但体内之气尚且逆乱而形成厥。厥则风、寒、湿三气随血脉上下运行，有时疼痛从上往下传，有时从下往上传，这种痹证发于血脉之中，不像众痹那样在左右之间转移。）
这种病，内部未涉及脏腑，外部也未发于皮肤，独自居于分肉之间，导致真气不能周流全身。（即全身性的痛症）所以命名为周痹。（周身气机闭塞不通。）
因此，治疗痹证，必须先切按并引导足六经的气血。（指足部的六条经脉。）以及大络中血液凝结而不通畅的。（应当用泻法）还有那些虚弱而脉象陷下、空虚的。（应当用补法调理。）
用熨法来温通经络。（适用于寒凝导致气机不周的病症。）对于肌肉抽搐、筋脉拘急转挛的情况。（螈急转筋的意思）通过牵引针法引导经气运行。（用针引导经气使其运行畅通。）
Zhongbi (a type of Bi syndrome characterized by fixed pain sites that alternate in onset) each remains at its respective location. It alternates in onset and cessation; it alternates in resting and rising. Symptoms on the right correspond to those on the left, and symptoms on the left correspond to those on the right. It is not capable of circulating throughout the body. It alternates in onset and rest.
(Note: "Each remains at its respective location" means that pain arises where pathogenic factors gather. It cannot circulate extensively up and down the body, but rather occurs alternatively on the left or right, alternating in onset and rest, with no fixed site of affliction. Hence, it is called Zhongbi.)
To treat this, even if the pain has ceased, one must still needle the original site of pain to prevent recurrence. (This states that one must needle the site where the initial pain occurred.)
Zhoubi (a type of Bi syndrome that moves along the blood vessels and circulates throughout the body) resides within the blood vessels. It follows the meridians upward and downward but does not correspond separately to locations on the left and right like Zhongbi. (It can move up and down, circulating throughout the body via the blood vessels, hence it is called Zhoubi.)
When pain develops from above downward, first needle the lower part to obstruct the pathogenic progression, then needle the upper part to eradicate the root cause. When pain develops from below upward, first needle the upper part to obstruct the pathogenic progression, then needle the lower part to eradicate the root cause. ("Guo" refers to removing the pathogen, specifically addressing the branch/symptom first; "Tuo" refers to severing the root, specifically addressing the root cause later.)
This occurs because Wind, Cold, and Dampness pathogens invade the exterior and lodge between the fenrou (muscle intervals), pressing upon fluids to form foam. The foam aggregates when exposed to Cold; aggregation causes pressure on the fenrou, leading to separation. Separation results in pain. (Pathogens lodging in the muscle surface gradually enter the fenrou, pressing fluids into juice and foam. When the foam encounters Cold, it aggregates and does not dissipate, thereby pressing and splitting the muscle texture to cause pain.)
When there is pain, the Shen (Spirit/Mind) focuses on the affected area. When the Shen focuses on the area, heat is generated. When there is heat, the pain resolves temporarily. When the pain resolves, Jue (Qi reversal/stagnation) occurs. Jue leads to the manifestation of other Bi syndromes, which present in this manner. (When in pain, the heart-mind focuses on the site, so the Shen returns there. Shen returning implies Qi returning; thus, heat is generated. Heat disperses Cold, temporarily relieving pain. However, the Qi remains rebellious, causing Jue. Jue allows the three pathogens to follow the blood vessels up and down; pain may transmit from top to bottom or bottom to top. This Bi manifests within the blood vessels, unlike Zhongbi which shifts between left and right.)
This condition is internally not located in the Zang-Fu organs and externally has not yet manifested in the skin; it resides solely between the fenrou, preventing the True Qi from circulating freely throughout the body. (Referring to systemic pain syndromes.) Therefore, it is named Zhoubi. (Blockage of Qi circulation throughout the body.)
Therefore, when treating Bi syndrome, one must first palpate and guide the Six Meridians of the Foot. (Referring to the six foot meridians.) As well as the large collaterals where blood is knotted and obstructed. (Should be treated with draining methods.) And those that are deficient, with sunken and empty pulses. (Should be treated with tonifying methods.)
Use moxibustion/heat therapy (Wen) to unblock the meridians. (Suitable for cases where Cold coagulation prevents Qi circulation.) For cases of muscle twitching and tendon contraction/spasm. (Meaning acute twitching and tendon turning.) Guide the Qi through needling manipulation. (Using needles to guide the Qi to promote its circulation.)
