Tianzong (SI11): The Shoulder Blade Point for an Aching Upper Back

Where Tianzong Sits

This point sits on the back, in the middle of the shoulder blade, in a soft hollow about a third of the way down from the bony ridge that crosses the top of the blade.

The line it belongs to begins at the outer corner of the little fingernail. It runs along the little-finger edge of the hand, up the back of the forearm and the back of the upper arm, then zigzags across the shoulder blade before climbing the neck to the cheek and the front of the ear. Vietnamese and Chinese texts call it the Small Intestine channel. This is its eleventh stop, and it sits at the centre of the zigzag, in the flat part of the blade.

The shoulder blade is a flat, triangular bone that rests on the back of the ribs. A sharp ridge runs across its upper part, from near the spine out to the tip of the shoulder. Below that ridge lies a broad, shallow hollow filled with muscle. The World Health Organization standard, published in 2008, places the point by drawing a line from the middle of that ridge down to the bottom tip of the blade. The point sits where the top third of that line meets the lower two thirds. The Vietnamese handbook by Ngo Trung Trieu gives a second check: it is roughly level with the fourth bump of the spine in the upper back, counting down from the large bump at the base of the neck.

The muscle filling the hollow is the one that turns the upper arm outward and holds the ball of the shoulder snug in its socket (the infraspinatus). It works every time you reach, lift a kettle, or hold your arm out in front of you. A nerve that runs across the top of the blade, the suprascapular nerve, supplies it. The skin over the point is served by nerves from the upper back, around the fourth level. That mix explains why a press here often feels dull and deep, and sometimes spreads a little toward the back of the shoulder.

Why This Spot

On the anatomical side, this is the busiest muscle on the back of the shoulder blade. It steadies the joint all day, and it tires quickly when the arms work out in front of the body for long periods. People who have spent years at desks, at sewing tables, behind the wheel or in the garden often find a tender knot right here. Pain from a stiff shoulder joint also tends to settle into this muscle, so the spot is often sore even when the problem started elsewhere.

In this tradition the point gathers the flow of the channel across the back of the shoulder. Its name is read as a meeting place under the sky: the upper body is the heavenly part, and the flat blade is where the channel collects before it turns upward to the neck. Thiên Tông, its Vietnamese name, carries the same picture. Teachers use it when the shoulder blade aches, when the shoulder will not turn, and when pain runs down the back of the upper arm.

What the Old Texts Say About Tianzong

The Vietnamese handbook of points and channels by Ngo Trung Trieu, published by Hong Duc, places it below the point at the top of the shoulder blade, in the hollow under the large bone. It lists it for pain of the shoulder blade and pain of the arm. That is a short list, and an honest one. The old writers used this spot for the back of the shoulder and the arm, and not much else.

The Systematic Classic of Acupuncture and Moxibustion, the Jiayi Jing, compiled by Huangfu Mi in the third century, set out the shoulder points of this channel in a set order, and that order still holds: one at the back of the armpit, one above it, then this one in the middle of the blade, then one above the ridge. Following that sequence with your fingers is a good way to understand the shoulder. The points walk across the back of the blade the way the ache usually does.

The WHO standard of 2008 kept the old placement and gave it a clean landmark: one third of the way down the line from the middle of the ridge to the bottom tip of the blade. Older Vietnamese teaching adds a plainer idea. If you press around the middle of the blade, one spot will be far more tender than the rest. That spot is the one to work.

In the wider tradition this point also has a reputation for easing a feeling of fullness across the chest and the side of the ribs, because the channel's inner branch is said to pass through the chest. That reputation comes from long use, not from proof. On this site we keep to what most people need it for: a shoulder blade that aches and an upper back that feels bound.

Points That Work With Tianzong

The first partner sits close by, at the back of the shoulder, where the arm joins the body. Let your arm hang and find the end of the crease at the back of the armpit; the point is about a thumb's width above it, in the edge of the shoulder muscle. In this tradition the two are commonly pressed together when the shoulder aches at the back and the arm will not lift.

The second sits on the top of the shoulder, halfway between the base of the neck and the bony tip of the shoulder, on the thick ridge of muscle you squeeze when someone rubs your shoulders. It is used with this one when tension runs from the neck down into the shoulder blade.

The third is on the hand. Make a loose fist and look at the little-finger edge: the point is at the end of the crease, right behind the knuckle of the little finger. It sits on the same line as this one, and many teachers press it first, then move to the back, when the neck and shoulder are stiff together.

How to Find and Press Tianzong

Getting Into Position

You cannot comfortably reach the middle of your own shoulder blade with your fingers. Do not twist the shoulder to try. Use one of two set-ups. For a tool, sit upright on a firm chair and hold a long-handled pressing tool, the hooked or S-shaped kind, in the hand opposite the sore side, with the hook over that shoulder. For a ball, stand with your back to a wall, feet a small step away from it, and place a firm ball, such as a tennis ball, between the wall and the middle of your shoulder blade. Let the arm on that side hang loose so the muscle is soft.

How to Find It

First, find the bony ridge. With the opposite hand, reach over your shoulder and feel the hard ridge running across the top of the shoulder blade. The point sits about a hand's width below the middle of that ridge on most adults, in the middle of the flat part of the blade. If someone can help, ask them to trace the blade: the ridge at the top, the bottom tip, and the line between them. One third of the way down is the area.

Now probe the area. With a tool, place the rounded tip there and press in small steps around the hollow. With a ball, bend your knees slightly and shift your body a little up, down and sideways so the ball moves over the area. Most of it will feel like ordinary muscle. One spot will sting: a small, sharp, pinpoint tenderness. That spot is the point. It is often surprisingly strong here, so start gently.

How to Press It

With the tool, keep the tip on the stinging spot and rub in small circles, about the size of a fingernail, roughly one each second. Pull the handle forward with the front hand to create the pressure; do not push with the sore shoulder. With the ball, keep the ball on the spot and make small circles with your body by shifting your weight. Keep the movement small. You want the tip or ball to stay on that one spot, not roll across the whole back.

How Much Pressure

A sharp sting under the tip is right. That tells you that you are on the point. The test is what happens when you lift off: the sting should fade within moments. If the pain stays after you lift off, if it spreads, or if the area turns swollen, hot or red, stop and leave it for several days. If you are holding your breath or your shoulder creeps up toward your ear, you are pressing too hard. With a ball, step your feet closer to the wall to lighten the pressure. Never throw your weight backward onto the ball.

How Long

Work each side for one to three minutes. Begin with about one minute, because this spot is often very tender at the start. As the days go on, add a little time, up to three minutes. Do both sides, even when only one complains, because the two shoulders share the load. Once or twice a day is enough. Longer sessions add soreness, not benefit.

When to Do It

Mid-morning suits a shoulder that is stiff on waking, once you have moved around a little. Late afternoon suits the ache that builds after a day at a desk, at the wheel or in the garden. Before bed is a good time too, as part of winding down. Do not press in the middle of the night. If an aching shoulder wakes you, pressing then tends to wake you further. Keep the pressing for daytime and the evening, and change your sleeping position or pillow if the shoulder keeps waking you.

What This Won't Do

It will not undo the reason your shoulder aches. Pain at the back of the shoulder often comes from long hours with the arms held forward, from a stiff shoulder joint, from wear in the joint itself, or from a neck that sends pain down into the blade. A point on the shoulder blade cannot argue with any of that. It works best alongside the plain things: getting up from the chair often, gentle shoulder rolls, a stretch across the chest, and a pillow that keeps the neck level.

It will not replace a diagnosis either. Pain between or under the shoulder blades that comes on suddenly, especially with sweating, breathlessness or pain in the chest, jaw or arm, needs emergency care, not pressing. A shoulder that suddenly will not lift after a fall needs to be seen, because a tendon can tear. Numbness, tingling or weakness running into the hand points to the neck and should be checked. Pain that keeps you awake every night, gets worse week on week, or comes with weight loss you cannot explain belongs with a doctor.

Safety First

Do not press over skin that is broken, burned, infected, badly bruised or rashy. Leave the area alone after a recent rib fracture, a recent shoulder injury or surgery, or with unexplained swelling or a lump. If you have osteoporosis or have been told your bones are thin, ask your doctor before using a ball against the wall, and keep the pressure light, because leaning your weight onto the ribs can be too much. If you take blood thinners or bruise easily, use lighter pressure and keep sessions short.

Stop at once if the pain stays after you lift off, spreads, or if the area becomes swollen, hot or red. Stop too for any electric jolt, tingling or numbness into the arm or hand. Nothing here requires you to push through pain. For the full list of cautions, read the full safety guide before you begin.

Questions People Ask

Where is the Tianzong (SI11) pressure point? Tianzong (SI11) sits in the middle of your shoulder blade. Picture a line from the middle of the bony ridge across the top of the blade down to the blade's bottom tip. The point lies about a third of the way down that line, in a soft hollow. In English it is called the Heavenly Gathering; in Vietnamese, Thiên Tông.

How can I press Tianzong on my own back? Two ways work well. Hold a long-handled pressing tool, the hooked or S-shaped kind, in the opposite hand and hook the rounded tip over your shoulder onto the spot. Or put a firm ball, such as a tennis ball, between your shoulder blade and a wall, and lean into it. Your hand alone rarely reaches the right place without straining the shoulder.

How long should I press Tianzong? One to three minutes on each side. Start with about a minute, because this spot is often very tender, then add a little time over the days, up to three minutes. Once or twice a day is plenty. Work both sides even if only one aches.

The spot hurts down my arm when I press it. Is that normal? A dull ache that spreads a little toward the back of the shoulder is common here and fades as soon as you lift off. An electric jolt, tingling into the hand, or pain that stays after you stop is not. Lift off, press more lightly, and if it keeps happening let a doctor check your neck and shoulder.

Can I use a ball against the wall if I have fragile bones? Ask your doctor first. A ball against a wall lets you lean your full weight onto the ribs, and bones thinned by osteoporosis do not like sudden heavy pressure. If you get the go-ahead, use a soft ball, stand close to the wall, and lean in gently.

Is this the point that is always sore when I work at a desk? Very often, yes. The muscle under it works to hold the arm and shoulder steady, and it tires when you reach forward for long hours, at a keyboard, a steering wheel or a sewing table. Pressing the point is useful, and so is getting up every half hour to roll your shoulders back.
