Shoulders That Click: What Noise Means and What It Does Not

Shoulders make noise. So do knees, hips, ankles and necks. For most people most of the time this means nothing at all, and the anxiety it produces does more harm than the noise does.

What causes the noise

Several things, most of them unremarkable.

Gas bubbles. Changes in pressure within a joint can cause dissolved gases to form bubbles, producing a pop. This is what happens when knuckles crack, and it is harmless. It cannot repeat immediately, which is why a joint that has just popped will not pop again for a while.

Tendons moving over bone. As a shoulder moves, tendons slide over bony surfaces, and sometimes they do so with a snap. Very common around the shoulder blade and the front of the shoulder.

Normal joint surfaces. Healthy cartilage is not perfectly smooth and normal movement can produce sound.

Scapular movement. The shoulder blade glides over the rib cage, and grinding or clunking there is common and usually painless.

The distinction that matters

The research is fairly clear that painless joint noise is not predictive of future problems. People with noisy shoulders do not go on to develop shoulder problems at notably higher rates.

So the question is not whether it makes a noise. It is whether any of the following is true:

Does it hurt? Noise with pain is worth assessing.

Does it catch or lock? A shoulder that catches at a specific point in the range, or that momentarily jams, is different from one that clicks freely.

Does it feel unstable? A sense that the shoulder might slip, or has slipped, particularly in certain positions, warrants assessment.

Did it follow an injury? New noise after a fall or a wrench is a different situation from noise you have had for a decade.

Is there weakness? Difficulty lifting or holding, particularly overhead, is a symptom rather than a noise.

If none of those apply, a clicking shoulder is a shoulder that makes a noise.

Why the reassurance matters

Being worried about a joint changes how you use it. People who believe a joint is damaged move it more guardedly, use it less, and lose range and strength as a result, and the reduced strength and range can then produce the pain they were worried about in the first place.

This is well documented across joints and it is why unnecessary alarm has a real cost.

What helps anyway

Whether or not the noise means anything, shoulders generally benefit from the same things, and most adults who sit at a desk are short of them.

Thoracic extension. A shoulder attached to a stiff upper back must find range it does not have. This is the most common contributing factor and the most commonly missed.

Scapular control. Work that trains the shoulder blade to move and stabilise properly against the rib cage. Wall slides, controlled pushing work, and shapes that load the shoulder blade in position.

External rotation strength. Usually the weak direction in people who sit and who train pushing more than pulling.

Range in the directions you have lost. For most desk workers, overhead and behind the back.

Strength work generally matters more than stretching for shoulders, which is the opposite of what people assume.

When to see someone

Pain that persists beyond a couple of weeks, catching or locking, a sense of instability, weakness, night pain, or anything that followed a significant injury. Also any sudden loss of movement.

Where a teacher helps

The distinction between extending the upper back and arching the lower back is the crux of most shoulder work, and it is invisible from inside. People spend months doing shoulder exercises that achieve nothing because the movement is coming from the wrong place.

Sessions are live on video, thirty or sixty minutes.

Questions people ask

Should I worry about my shoulder clicking?

If it is painless, does not catch or lock, and did not follow an injury, it is generally not a cause for concern. Painless joint noise is not predictive of future problems.

What causes the popping sound?

Usually gas bubbles forming in the joint, tendons sliding over bone, or the shoulder blade moving across the rib cage. All are ordinary features of a moving joint rather than signs of damage.

When should I get it looked at?

If it hurts, catches or locks, feels unstable, is weak, wakes you at night, or if the noise appeared after a fall or a wrench. Sudden loss of movement also warrants assessment.

What helps a stiff, noisy shoulder?

Thoracic extension first, since a stiff upper back forces the shoulder to compensate, then scapular control and external rotation strength. For shoulders, strength work generally matters more than stretching.
