Suwen: Treatise on Needling Low Back Pain, Chapter 41

Plain-Language Translation and Interpretation of "Suwen · Treatise on Needling Low Back Pain, Chapter 41"

Overall Paraphrase

This chapter is a dedicated monograph in the Suwen focusing on channel-pattern identification and needling methods for low back pain. The ancients classified low back pain into multiple types according to different channels and collateral vessels, selecting different needling techniques based on the pain location, direction of radiation, and accompanying symptoms.

Foot-Taiyang Channel Low Back Pain
When disease of the Foot-Taiyang Bladder Channel causes low back pain, the pain radiates to the nape, spine, buttocks, and back, as if carrying something heavy. Needling may be performed at Xizhong (center of the popliteal fossa behind the knee) on the Foot-Taiyang main channel to draw blood; in spring, do not draw blood.

Shaoyang Channel Low Back Pain
Low back pain due to the Foot-Shaoyang Gallbladder Channel feels like needles piercing the skin, gradually worsening, with inability to bend forward, lean backward, or turn the head. Needling may be performed at the prominent bone on the lateral side of the knee to draw blood from the Shaoyang channel; in summer, do not draw blood.

Yangming Channel Low Back Pain
Low back pain due to the Foot-Yangming Stomach Channel causes inability to turn the head; when turning, it seems as if seeing foreign objects before the eyes; the person is prone to grief. Needling may be performed at three points on the anterior aspect of the tibia, regulating above and below to induce bleeding; in autumn, do not draw blood.

Foot-Shaoyin Channel Low Back Pain
Low back pain due to the Foot-Shaoyin Kidney Channel radiates to the medial aspect of the spine. Needling may be performed at two points above the medial malleolus; in spring, do not draw blood—if too much blood is drawn, the righteous qi is not easily restored.

Jueyin Channel Low Back Pain
Low back pain due to the Foot-Jueyin Liver Channel makes the waist feel taut like a drawn bowstring. After palpating a cord-like nodule between the calf and heel at the lateral margin of the gastrocnemius muscle, needle at three points. The patient may sometimes be talkative, sometimes silent with a displeased expression.

Jiemai (Relaxed Vessel) Low Back Pain
Low back pain due to Jiemai disease radiates to the shoulders, causes blurred vision, and sometimes enuresis. Needling may be performed at the boundary between sinew and muscle in the knee, on the transverse collateral at the lateral aspect of the popliteal fossa, bleeding until the blood color changes.
In another type of Jiemai low back pain, the waist feels pulled as if by a belt, often seeming about to break, with a tendency to fear. Needling may be performed at the millet-sized nodular collaterals in the popliteal fossa; the ancients observed dark blood spurting out, and continued until fresh red blood appeared.

Tongyin Vessel Low Back Pain
Low back pain due to the Tongyin Vessel feels like a small hammer striking inside, with local swelling. Needling may be performed at three points at the Juegu end above the lateral malleolus.

Yangwei Vessel Low Back Pain
Low back pain due to the Yangwei Vessel manifests with swelling at the painful site. Needling may be performed at the intersection of the Yangwei Vessel and Foot-Taiyang Channel, approximately one chi below the calf belly.

Hengluo Vessel Low Back Pain
Low back pain due to the Hengluo Vessel prevents bending and extending; when leaning backward, the person fears falling. This is mostly caused by lifting heavy weights injuring the lower back, blockage of the Hengluo, and blood stasis. Needling may be performed at two points taken transversely between the sinews on the lateral side of the popliteal fossa, several cun above.

Huiyin Vessel Low Back Pain
Low back pain due to the Huiyin Vessel manifests with sweating at the painful site; after the sweat dries, the person desires water, and after drinking, wishes to move about. Needling may be performed at three points on the Zhiyang Vessel, at the transverse location five cun below the popliteal fossa, above the Qiao region, bleeding where blood vessels are visibly engorged.

Feiyang Vessel Low Back Pain
Low back pain due to the Feiyang Vessel manifests with discomfort and fullness at the painful site; in severe cases, sadness and fear. Needling may be performed at a point five cun above the medial malleolus, anterior to the Shaoyin channel at its intersection with the Yinwei Vessel.

Changyang Vessel Low Back Pain
Low back pain due to the Changyang Vessel radiates to the chest, causes blurred vision, and in severe cases, the back arches backward, the tongue curls and cannot speak. Needling may be performed at two points approximately two cun anterior to the great sinew above the medial malleolus and posterior to the Taiyin channel.

Sanmai (Dispersing Vessel) Low Back Pain
Low back pain due to the Sanmai manifests with heat in the lower back; when severe, restlessness; below the waist it feels as if a piece of wood is laid horizontally; in severe cases, enuresis. Needling may be performed with three needles at the boundary between bone and flesh anterior to the knee, at the lateral束 [bound] vessel region.

Rouli Vessel Low Back Pain
Low back pain due to the Rouli Vessel prevents coughing; coughing causes the sinews and vessels to cramp. Needling may be performed at two points lateral to the Taiyang channel and posterior to the Juegu of the Shaoyang channel.

Comprehensive Pattern-Based Channel Selection
When low back pain travels upward along both sides of the spine to the head, with tightness and discomfort in the neck and back, blurred vision, and a feeling of about to fall, needle the Foot-Taiyang channel at the popliteal fossa to draw blood.
When low back pain is accompanied by upper-body cold, select Foot-Taiyang and Foot-Yangming; upper-body heat, select Foot-Jueyin; inability to bend or extend, select Foot-Shaoyang; internal heat with wheezing, select Foot-Shaoyin, and also needle the popliteal fossa to draw blood.
When low back pain is accompanied by upper-body cold and inability to turn the head, select Foot-Yangming; upper-body heat, select Foot-Taiyin; internal heat with wheezing, select Foot-Shaoyin.
When defecation is difficult, select Foot-Shaoyin; when the lower abdomen is distended and full, select Foot-Jueyin.
When low back pain feels like breaking, with inability to bend, extend, or lift, select Foot-Taiyang; when pain radiates to the medial aspect of the spine, select Foot-Shaoyin.

Low Back Pain Radiating to the Lower Abdomen and Hypochondrium
When low back pain radiates to the lower abdomen and hypochondrium, with inability to lean backward, needle at the lumbosacral junction and at the fleshy and thick regions of the hip bones on both sides. The ancients determined the number of needling procedures according to the waxing and waning of the moon, believing that relief would come immediately after needling. For disease on the left, take the right side; for disease on the right, take the left side.

🧠 Deep Understanding

Core Principles 💡

• Differentiating Low Back Pain by Channels: This chapter does not treat low back pain as a single disease entity, but rather classifies it under the Foot-Taiyang, Shaoyang, Yangming, Shaoyin, and Jueyin channels, as well as specific vessels such as the Jiemai, Hengluo, and Feiyang, based on pain location, radiation direction, accompanying emotional and somatic symptoms. This embodies the diagnostic approach of "where the channel passes, there treatment can reach."
• Pricking Collaterals to Draw Blood as the Core: Throughout the chapter, expressions such as "draw blood," "stop when red blood appears," and "bleed where visibly engorged" frequently appear, indicating that the ancients believed these types of low back pain were mostly related to blood stasis obstructing the collaterals and collateral vessels being blocked. The change of blood color from dark to red was regarded as a sign of stasis gradually resolving and collaterals becoming unblocked.
• Seasonal and Needling Contraindications: Repeated mentions of "do not draw blood in spring," "do not draw blood in summer," and "do not draw blood in autumn" reflect the ancient practice of adjusting needling methods according to the seasonal ebb and flow of qi and blood, avoiding excessive depletion of righteous qi.
• Correspondence Between Heaven and Human: The final statement "using the waxing and waning of the moon to determine the number of needling procedures" reflects the application of ancient numerological concepts in acupuncture.
• Crossed Left-Right Point Selection: "For disease on the left, take the right; for disease on the right, take the left" resembles the later Miaoci (opposite-side needling) method, reflecting an early understanding of bilateral corresponding regulation.

Modern Perspective 🌟

• Modern medicine recognizes that the causes of low back pain are complex, commonly including muscle-fascial injury, lumbar disc herniation, joint degeneration, and nerve compression. The symptoms attributed to different channels in this chapter, such as "radiating to the nape and spine," "inability to turn the head," and "pain radiating to the medial aspect of the spine," bear certain phenomenological similarities to different nerve distribution territories and referred pain patterns, but channels cannot be directly equated to neural or vascular anatomical structures.
• Bloodletting had its historical context in antiquity, but modern high-quality evidence does not support it as a routine therapy for low back pain, and it carries risks of infection, vascular and nerve injury, and bleeding. In particular, descriptions such as "arching backward, tongue curled, unable to speak" and "blurred vision, about to collapse" may suggest conditions requiring urgent neurological or medical evaluation, and one must not self-administer needling based on ancient texts.
• "Using the waxing and waning of the moon to determine the number of needling procedures" and "seasonal prohibitions" lack modern scientific basis and should be understood as medical history and philosophical concepts.
• The value of this chapter lies in its systematic symptom observation and channel-based classification approach, which holds documentary significance for understanding Traditional Chinese Medicine diagnostic thinking, but should not be directly used as a basis for modern clinical diagnosis and treatment.

Health Preservation Insights ⚡

• Protect the Lower Back from Injury: Avoid bending suddenly while lifting heavy objects, reduce prolonged sitting or standing, keep the lower back warm, and prevent external twisting injuries.
• Move with Gentleness: Discomfort in the lower back during bending, turning, or coughing suggests that daily activities should be smooth and gentle, avoiding sudden twisting and excessive backward extension.
• Maintain Emotional Equanimity: The chapter repeatedly mentions "prone to grief" and "prone to fear"—emotional fluctuations can aggravate physical tension. Maintaining a stable mindset and moderate stretching can help reduce lower back discomfort.
• Do Not Self-Administer Bloodletting: If low back pain recurs, or is accompanied by lower limb numbness, bowel or bladder dysfunction, fever, severe pain, visual abnormalities, or speech difficulties, seek medical evaluation promptly rather than performing needling or bloodletting on yourself according to ancient texts.
