Shoulder Pain
The shoulder is usually the victim, not the culprit.
2/3
of shoulder pain involves the rotator cuff
Rotator cuff pain, impingement, and frozen shoulder each behave differently. Sorting which one you have — and screening the neck and shoulder blade — is what separates a six-week recovery from a six-month one.
What it feels like
- Pain reaching overhead, behind your back, or across your body
- Difficulty sleeping on the affected side
- A painful arc partway through raising the arm
- Weakness lifting or rotating, distinct from pain limiting you
- Progressive stiffness in all directions (typical of frozen shoulder)
- Clicking, catching, or a sense of instability
What tends to cause it
- Rotator cuff tendinopathy or tearing, partial or full thickness
- Subacromial impingement from poor scapular mechanics
- Adhesive capsulitis — frozen shoulder
- Labral injury, often in throwing athletes or after dislocation
- Acromioclavicular joint irritation or arthritis
- Referred pain from the cervical spine
The shoulder trades stability for range. It is a shallow ball-and-socket where the socket covers only a small portion of the head of the humerus, held together largely by soft tissue.
That design gives you more range of motion than any other joint you own. It also means the whole thing depends on coordinated muscular control, and when the control fails, the structures that get compressed complain first.
Scapulohumeral rhythm, and why it matters
Raising your arm overhead is not one joint moving. Roughly two-thirds of the motion comes from the humerus at the glenohumeral joint, and roughly one-third from the scapula rotating upward across the rib cage. That ratio matters.
When the scapula does not rotate — because the serratus anterior and lower trapezius are not doing their job, or because a stiff thoracic spine will not let it — the humerus has to make up the entire range on its own. Doing so drives the greater tuberosity up under the acromion, and the supraspinatus tendon is what happens to be in between.
That is impingement. And notice that nothing about it is fundamentally a shoulder problem.
Three presentations worth distinguishing
Rotator cuff tendinopathy — painful arc between roughly 60 and 120 degrees, pain with resisted testing, night pain, full passive range available.
Frozen shoulder — loss of range in every direction, and critically, passive range is lost too. Someone else moving your arm cannot get there either. External rotation is affected first and worst.
Cervical referral — shoulder pain with normal shoulder testing, no clear positional pattern, often accompanied by neck stiffness or symptoms below the elbow.
These are not subtle distinctions once you test for them, and they lead to entirely different plans.
The loading conversation
The most common thing we undo is months of rest. Tendons are living tissue that adapts to demand. Remove the demand and they lose capacity, so returning to normal activity puts you back exactly where you started, with less tissue tolerance than before.
Loading a painful tendon feels wrong and it is well supported. We start with isometrics because they reliably reduce tendon pain, then progress to heavy slow resistance. It takes twelve weeks and it works.
How we treat it here
Separate weakness from pain inhibition
A muscle that is weak and a muscle that is inhibited by pain test similarly and mean entirely different things. We test with and without pain provocation to distinguish them, because a genuine cuff tear and a painful but intact cuff need different plans.
Watch the shoulder blade
Roughly a third of your overhead reach comes from the scapula rotating on the rib cage. When it does not, the humerus runs out of space and the cuff gets compressed. Most impingement is a scapular control problem wearing a shoulder costume.
Screen the neck
C5 and C6 refer directly into the shoulder and upper arm. A shoulder that hurts at rest, at night, with no positional pattern, and with normal shoulder testing is frequently a neck.
Load the tendon
Tendinopathy responds to progressive loading, not to rest. Isometrics for pain relief early, then heavy slow resistance. This is well-established and it is the part patients most often skip.
Shoulder pain
Questions we get about this.
How do I know if I have a rotator cuff tear?
You often cannot tell from symptoms alone, and imaging is less decisive than people expect. Rotator cuff tears are present in a large share of pain-free people over 60 — the tissue degenerates with age and frequently causes no trouble. What matters clinically is whether you can generate force and control the arm. Many partial and even full-thickness tears function well and do not require surgery.
What is frozen shoulder and why does it take so long?
Adhesive capsulitis is a genuine contracture of the joint capsule, and it follows a characteristic course — a painful freezing phase, a stiff frozen phase, then gradual thawing. The whole thing commonly runs one to three years. The defining feature is loss of passive external rotation — someone else cannot move your arm through range either. Treatment during the painful phase is about comfort and maintaining what range you have; aggressive stretching then makes it worse. It is more common in diabetics and in women aged 40 to 60.
Should I rest it?
For tendinopathy, no. Rest reduces pain temporarily and reduces tendon capacity permanently, so you return to the same load with less tolerance. Modify what aggravates it, keep loading in a pain-tolerable range, and progress. Genuine rest is for acute tears and post-surgical protocols.
Why does it hurt so much more at night?
Lying down removes the small distraction force gravity applies to the joint when you are upright, which narrows the subacromial space. Inflammatory activity also peaks overnight. Try sleeping with a pillow supporting the arm slightly forward and away from your side.
