Key Takeaways
- In TCM, back pain is usually caused by Qi and blood stagnation in the local meridians, Cold and Dampness lodging in the muscles, or Kidney deficiency failing to nourish the lower back.
- Six points form the core back-pain protocol: Shenshu (BL23), Weizhong (BL40), Chengshan (BL57), Kunlun (BL60), Yaoyan, and Hegu (LI4).
- There is a famous TCM saying: "For back pain, seek Weizhong" (腰背委中求) — the point at the back of the knee is the master point for the entire back.
- Upper back pain benefits most from Chengshan, Kunlun, and Hegu; lower back pain responds best to Shenshu, Weizhong, and Yaoyan.
- Pregnancy warning: Do not press Hegu (LI4) during pregnancy, and use only light pressure on the lower back points if pregnant.
1. Why Acupressure Works for Back Pain
Back pain is one of the most common reasons people visit a doctor, miss work, or reach for pain medication. It is also one of the conditions Traditional Chinese Medicine treats most effectively — partly because TCM does not see the back as an isolated structure, but as a crossroads where several of the body's deepest systems meet.
In the TCM view, the back is governed primarily by the Bladder meridian, the longest channel in the body, which runs from the inner eye, over the top of the head, down the entire spine on both sides, and down the backs of the legs to the little toes. The Bladder meridian also partners with the Kidney, the organ system in TCM that rules the lower back, the bones, and the marrow. When your Kidney energy is strong, the lower back is supported and resilient. When it is weak — through overwork, aging, illness, or chronic stress — the lower back loses its nourishment and becomes a vulnerable spot that aches easily and heals slowly.
Back pain in TCM usually falls into one of three patterns. The first is Qi and blood stagnation — energy and blood become blocked in the local meridians after a sprain, strain, poor posture, or repetitive movement. This is the acute, "stuck," stabbing pain that often follows a specific incident. The second is Cold and Dampness invading the back — cold and damp weather, sitting on cold surfaces, or working in a damp environment cause the muscles to contract and the meridians to slow, producing a heavy, stiff, aching pain that is worse in cold or wet weather and better with warmth. The third is Kidney deficiency — a chronic, dull, deep ache in the lower back that comes on gradually, feels better with rest and warmth, and is accompanied by tiredness, weak knees, and frequent urination. Many people have a mix of all three.
Acupressure addresses all three patterns. By pressing points along the Bladder meridian and related channels, you unblock stagnant Qi and blood, warm and dry Cold and Dampness, and strengthen the Kidney that supports the lower back. The beauty of the approach is that several of the most powerful back-pain points are not even on the back — they are on the legs and hands, which means you can reach them easily yourself even when your back is too sore to touch.
2. How to Practice: The Basic Technique
Before learning the individual points, understand the technique that applies to all of them.
Pressure and Contact
Use the pad of your thumb, the tip of your index finger, or — for points on the legs — a knuckle. Apply firm but tolerable pressure until you feel a dull ache or a sensation that radiates outward. This is the Deqi sensation that tells you the point is activated. On points you cannot reach yourself (like those on your own back), ask a partner or use a tennis ball against a wall.
Duration and Breathing
Hold each point for 1 to 2 minutes, or 20 to 40 slow breaths. Breathe deeply through the nose, exhaling longer than you inhale. With each exhale, imagine tension releasing from the back. The extended exhale relaxes the deep back muscles and improves blood flow to the area.
Timing and Position
Press the points 2 to 3 times a day during a flare-up, and once a day for chronic prevention. Sit comfortably or lie down — lying on your back with knees bent is often the most relaxing position for back pain. For points on the back of the legs, you can bend the knee and reach around, or sit on a chair and cross one ankle over the opposite knee.
3. Point 1: Shenshu (BL23) — The "Kidney Shu"
Shenshu, meaning "Kidney Transport Point," is the back-shu point of the Kidney organ. In TCM, the back-shu points are where each organ's energy gathers on the back, and pressing them directly tonifies that organ. Shenshu is the primary point for strengthening the Kidney and nourishing the lower back.
Location
Shenshu (BL23) is located on the lower back, 1.5 cun (about two finger-widths) lateral to the lower border of the spinous process of the second lumbar vertebra (L2). A practical way to find it: the points sit at the level of the lower border of your lowest ribs, about two finger-widths out from the spine on each side. It belongs to the Bladder meridian.
How to Find It
Stand or have a partner help. Find the lowest rib on your side, then trace it to where it meets the spine. The point is at that level, about two finger-widths to the side of the spine. When you are sore there, the point is often tender and slightly swollen.
How to Press
Because this point is on your own back, the best method is to lie on your back and place two tennis balls under the points, letting your body weight provide steady pressure. You can also make soft fists and rub the area up and down with the knuckles, or ask a partner to press with both thumbs. Hold or maintain pressure for 2 to 3 minutes. Warmth helps — a heated rice bag or hot water bottle over this area works synergistically with the point.
What It Does
Shenshu tonifies the Kidney, strengthens the lower back, and benefits the bones. It is the essential point for chronic lower back pain that comes on slowly, feels dull and deep, worsens with fatigue, and improves with rest and warmth — the classic picture of Kidney deficiency. By strengthening the Kidney system that rules the lower back and bones, pressing Shenshu addresses the root weakness rather than just the symptom. It is also excellent for the knee weakness, frequent urination, and cold lower back that often accompany Kidney-deficient back pain.
4. Point 2: Weizhong (BL40) — The "Middle of the Crease"
Weizhong, meaning "Middle of the Crease," sits at the center of the back of the knee. It is the most famous point in all of Chinese medicine for back pain, and there is a saying that every practitioner learns on their first day: "For back pain, seek Weizhong" (腰背委中求). The reason is simple — the Bladder meridian passes through the knee and continues up the back, so releasing the point at the knee clears stagnation all along the channel that governs the entire spine.
Location
Weizhong (BL40) is located at the midpoint of the transverse crease at the back of the knee, in the soft hollow of the popliteal fossa. It belongs to the Bladder meridian.
How to Find It
Sit on a chair and cross one ankle over the opposite knee, letting the knee fall open so the back of the knee faces upward. Find the horizontal crease where the knee bends. The point is at the very center of that crease, in the soft depression between the two tendons. It is often quite tender when there is back pain, even if the knee itself feels fine.
How to Press
Use your thumbs to press firmly into the center of the crease. Apply moderate to strong pressure for 1 to 2 minutes on each knee. You can also use a slow circular motion. If the point is very tender, that tenderness is confirmation — press through it gently until the ache softens. Pressing both knees in sequence is more effective than one alone.
What It Does
Weizhong relieves back pain, unblocks the Bladder meridian, and moves stagnant blood. It is the master point for acute back pain — the sudden, stabbing, "thrown-out" back that often follows a twist, lift, or sudden movement. It is equally effective for chronic stiffness. Because it sits at the midpoint of the Bladder channel, releasing Weizhong clears stagnation throughout the entire channel, from the lower back up the spine and down the legs. For many people, pressing Weizhong produces almost immediate loosening of a locked-up lower back.
5. Point 3: Chengshan (BL57) — The "Mountain Support"
Chengshan, meaning "Mountain Support," sits on the belly of the calf muscle, which in Chinese anatomy was thought to resemble a mountain. The name captures both its location and its function — it "supports" the back and legs like a mountain holds up the land.
Location
Chengshan (BL57) is located on the back of the lower leg, in the center of the calf muscle, about midway between the back of the knee and the heel. More precisely, it sits in the V-shaped depression that forms where the two heads of the gastrocnemius muscle meet. It belongs to the Bladder meridian.
How to Find It
Stand on your toes or flex your foot. The calf muscle will bulge and form a V-shape at its lower edge. The point is in the center of that V, on the back of the leg. Pressing it usually produces a strong ache that may radiate down toward the ankle.
How to Press
Sit down and bend the knee. Use your thumb or two fingers to press into the center of the calf at the point. Apply firm pressure for 1 to 2 minutes on each leg. This point can take strong pressure, and it is often one of the most tender points on the body when there is back tension — press through the tenderness until it softens.
What It Does
Chengshan relaxes the muscles and sinews, unblocks the meridian, and eases lower back and leg pain. It is particularly effective for back pain that radiates down the legs — the type often associated with sciatica — and for the heavy, stiff, cramping calves that accompany chronic back tension. It is also a key point for relieving foot and leg cramps. Because the Bladder meridian runs through the calf and up the back, releasing Chengshan frees the entire channel and takes pressure off the lower back. It is especially useful for upper back pain that includes neck and shoulder tension, since the meridian connects the two.
6. Point 4: Kunlun (BL60) — The "Kunlun Mountains"
Kunlun is named after the Kunlun Mountains, the great mountain range of western China — a fitting name for a point that supports the entire structure of the back and legs from below, just as a mountain range supports a continent.
Location
Kunlun (BL60) is located on the outer ankle, in the depression between the highest point of the outer ankle bone (lateral malleolus) and the Achilles tendon. It belongs to the Bladder meridian.
How to Find It
Find the bony point of your outer ankle. Slide your finger backward toward the heel. You will fall into a shallow depression just in front of the Achilles tendon — that is Kunlun. Pressing it usually produces a mild ache.
How to Press
Use your thumb to press inward and slightly upward toward the ankle bone. Apply moderate pressure for 1 to 2 minutes on each ankle. You can use your index finger to press while supporting the foot with the other hand. Gentle circular pressure also works well.
What It Does
Kunlun relieves back pain, unblocks the meridian, and promotes labor (it is also used clinically to assist delivery — another reason to avoid it in pregnancy). For back pain, it is excellent for the stiff, aching lower back that radiates down the outer leg, and for pain that feels worse with movement. As the last major point on the Bladder meridian before it leaves the body, Kunlun helps drain stagnation downward and out, which relieves pressure along the entire channel up the back. It pairs beautifully with Weizhong and Chengshan as a three-point leg combination for any back pain.
7. Point 5: Yaoyan (腰眼) — The "Waist Eyes"
Yaoyan, meaning "Waist Eyes" or "Lumbar Eyes," is an extra point that does not belong to a numbered meridian but has been used in folk and clinical practice for centuries. Its name comes from the two small dimples it sits in, which resemble a pair of eyes on the lower back.
Location
Yaoyan is located on the lower back, in the two soft depressions just below the fourth lumbar vertebra, about 3.5 cun (roughly four to five finger-widths) lateral to the spine on each side. A simple way to find it: locate the dimples at the very top of your buttocks — the point sits in or near those dimples.
How to Find It
Stand or lie on your stomach. Find the two natural dimples at the top of the buttocks, roughly level with the top of the hip bones. Press into the soft tissue in and around these dimples. When you have lower back pain, this area is usually tender and tight.
How to Press
Because you cannot easily reach both sides yourself, lie on your back and place two tennis balls under the points, or ask a partner to press with both thumbs. You can also make fists and rub the area briskly in circles with the knuckles — this "rubbing the kidneys" technique warms the lower back and is a daily longevity practice in China. Hold or rub for 2 to 3 minutes. Warmth greatly enhances the effect.
What It Does
Yaoyan is a local point for lower back pain that directly relaxes the muscles of the lumbar region and the gluteal attachment. It is especially good for the aching, heavy, fatigued lower back that comes from standing too long, lifting, or chronic weakness. Because it sits directly over the sacroiliac joint, pressing it relieves the deep pelvic-lumbar ache that many people feel at the base of the spine. It is also a traditional point for tonifying the Kidney and warming the lower back, making it valuable for both acute and chronic pain.
8. Point 6: Hegu (LI4) — The "Joining Valley"
Hegu, meaning "Joining Valley," is the most widely used analgesic point in Chinese medicine. While it sits on the hand, far from the back, it is included here because of its remarkable ability to stop pain anywhere in the body and to promote the free flow of Qi through the meridians.
Hegu (LI4) is strictly contraindicated during pregnancy. It is documented to stimulate uterine contractions and has been used to induce labor. Never press LI4 if you are pregnant or trying to conceive. If you are pregnant and have back pain, skip this point and focus on the leg points, using only light pressure on the lower back. Always consult your obstetrician first.
Location
Hegu (LI4) is located on the back of the hand, in the fleshy web between the thumb and index finger, at the highest point of the muscle bulge that forms when you press the thumb and index finger together. It belongs to the Large Intestine meridian.
How to Find It
Press your thumb and index finger together. A bulge of muscle rises between the two bones on the back of the hand. Hegu is at the peak of that bulge. Separate the fingers and press into the same spot — you will feel a deep ache that may radiate.
How to Press
Use the thumb of your opposite hand to press firmly into the point, angling toward the index-finger bone. Apply strong, steady pressure for 1 to 2 minutes on each hand. A pinching motion with thumb on top and index finger underneath also works. This point tolerates firm pressure — press deeply, but stop if the ache becomes sharp.
What It Does
Hegu moves Qi and blood, stops pain, and unblocks the meridians. For back pain, it is most useful as a "distal" point — pressed in combination with local points to amplify the overall pain-relieving effect and to promote the free flow of energy that clears stagnation. It is especially helpful when back pain is accompanied by tension headaches, jaw tightness, or neck stiffness, since Hegu relieves all of these. Think of it as the point that "opens the channels" so the other points can work more effectively.
9. Different Routines for Upper and Lower Back Pain
Not all back pain is the same, and the points you emphasize should match where your pain is. Here are two focused routines — one for the upper back and one for the lower back — followed by a combined full routine.
Upper Back Pain Routine
Upper back pain usually involves tension between the shoulder blades, often from desk work, phone use, or stress. It responds well to the distal (far-from-the-pain) points.
- Chengshan (BL57) — both calves, 2 min. Releases the Bladder channel from below.
- Kunlun (BL60) — both ankles, 2 min. Drains stagnation downward and out.
- Hegu (LI4) — both hands, 2 min. Opens the channels and relieves the neck and shoulder tension that often travels up to the upper back.
- Weizhong (BL40) — both knees, 2 min. The master point that benefits the whole back.
Lower Back Pain Routine
Lower back pain is the most common type and often involves the lumbar muscles, the sacroiliac joint, or the Kidney-deficient ache described above. It responds best to local points combined with the distal master point.
- Shenshu (BL23) — lower back, 2-3 min. Use tennis balls or a partner. Strengthens the Kidney and warms the lower back.
- Yaoyan — the dimples at the top of the buttocks, 2-3 min. Local relief for the lumbar region.
- Weizhong (BL40) — both knees, 2 min. The master point — "for back pain, seek Weizhong."
- Kunlun (BL60) — both ankles, 2 min. Drains stagnation and completes the leg combination.
Tips that make both routines more effective:
- Use warmth. A hot water bottle, rice bag, or warm bath over the lower back before pressing amplifies the effect, especially for Cold-type pain.
- Do not press directly on a fresh injury or swollen area. Use the distal leg points instead until the acute swelling subsides.
- Combine with gentle movement. After pressing, do slow cat-cow stretches or gentle qigong to keep the newly moving Qi flowing.
- Sip warming tea. Ginger tea or ginseng tea warms the body from the inside and supports the Kidney.
10. Safety and Precautions
Acupressure for back pain is safe for most people, but a few important cautions apply.
Never press Hegu (LI4) during pregnancy. It can stimulate uterine contractions. In addition, avoid deep pressure on the lower back points (Shenshu, Yaoyan) and the sacrum during pregnancy, especially in the third trimester. If you are pregnant and have back pain, the leg points (Weizhong, Chengshan, Kunlun) with light pressure are generally safer, but always consult your obstetrician or a qualified TCM practitioner first.
General Safety Guidelines
- Never press on broken skin, bruises, swollen areas, or varicose veins. Choose a different point if the area is damaged.
- Do not press on the spine itself. Work on the muscles beside the spine, not directly on the bony vertebrae.
- Avoid acupressure immediately after a serious acute injury. If you suspect a fracture, herniated disc with numbness or loss of bowel/bladder control, or a severe sprain, seek medical care first.
- Do not replace medical care. Acupressure is supportive. If your back pain radiates down the leg with numbness or weakness, follows an accident, or is accompanied by fever or unexplained weight loss, see a doctor promptly.
- When to see a doctor. Seek medical attention for back pain that lasts more than a few weeks, worsens despite self-care, follows a fall or accident, or causes leg weakness, numbness, or changes in bladder or bowel function.
Pressure and Discomfort
Pressure should feel like "good hurt" — a dull, spreading ache — never sharp, electric, or shooting pain. Sharp pain means you are pressing too hard or are slightly off the point. Reduce pressure immediately and reposition. Mild soreness after a session is normal but should fade within a day.
Frequently Asked Questions
How long does it take for acupressure to work for back pain?
Many people feel relief within 15 to 30 minutes of pressing the points, especially the distal points on the legs like Weizhong (BL40) and Kunlun (BL60). For chronic back pain, consistent practice two to three times a day for one to two weeks typically brings noticeable improvement. Acupressure works cumulatively, so regular pressing over time produces better and longer-lasting results than occasional use. Keep a simple pain diary to track your progress day by day.
Which acupressure point is best for lower back pain?
Weizhong (BL40), located at the center of the back of the knee, is the most famous point for lower back pain. There is a classic TCM saying — "For back pain, seek Weizhong" (腰背委中求) — that every practitioner learns. For the strongest effect, combine it with Shenshu (BL23) on the lower back to strengthen the Kidney, and Kunlun (BL60) at the ankle to drain stagnation downward. These three points together form the core lower-back combination used in clinics worldwide.
Is acupressure safe for back pain during pregnancy?
Partial caution is needed. Hegu (LI4) on the hand is strictly contraindicated during pregnancy because it can stimulate uterine contractions. The other points in this routine are generally safe, but avoid pressing deeply on the lower back and sacrum (Shenshu, Yaoyan) during pregnancy, especially in the third trimester. The leg points (Weizhong, Chengshan, Kunlun) with light to moderate pressure are usually the safest choice. Always consult your obstetrician or a qualified TCM practitioner before starting acupressure during pregnancy.
Can acupressure help with chronic back pain or only acute flare-ups?
Acupressure helps both. For acute flare-ups — the sudden, stabbing, "thrown-out" back — pressing the points can reduce pain within minutes to hours, especially Weizhong and Hegu. For chronic back pain, daily practice over weeks addresses the underlying patterns, such as Kidney deficiency or Qi and blood stagnation, that keep the pain returning. Chronic conditions benefit most from combining acupressure with gentle qigong, warming foods, and attention to posture. Expect gradual but real improvement over three to four weeks of daily practice.
