Shoulder Pain

Medical terms: Shoulder Arthralgia • Rotator Cuff–Related Shoulder Pain • Glenohumeral Pain

The shoulder is a highly mobile system rather than a single joint. Pain may arise from the rotator cuff, bursa, capsule, biceps tendon, acromioclavicular joint, ball-and-socket joint, bone or surrounding muscles. The neck, nerves, chest and upper abdominal organs can also refer pain to the shoulder region.

Most non-traumatic shoulder pain improves with a clear diagnosis, sensible activity modification and progressive exercise. Sudden severe pain, deformity, inability to move after injury, fever, persistent numbness or a cold hand needs earlier assessment. Shoulder or arm pain with chest pressure, sweating, nausea or breathlessness is an emergency—not a routine orthopaedic problem.

Some shoulder or arm symptoms need emergency assessment

Seek Urgent Medical Help for These Warning Signs

  • A shoulder that looks out of place or has changed shape, or severe pain and inability to move the arm after a fall, collision or seizure.
  • An open wound, visible bone, rapidly increasing swelling or severe bruising after injury.
  • A hand that becomes cold, pale, blue or grey, or new persistent numbness, weakness or loss of pulse.
  • A hot, very painful shoulder with fever, chills, confusion or feeling seriously unwell. A deep joint infection may not produce obvious redness.
  • Sudden shoulder or arm pain with chest pressure, heaviness or squeezing, breathlessness, sweating, nausea, faintness, or pain spreading to the jaw, back or opposite arm.
  • New facial droop, inability to hold up one arm, speech difficulty, sudden severe imbalance or another possible stroke symptom.
  • Shoulder-tip pain after significant chest or abdominal trauma with abdominal pain, breathing difficulty, dizziness, fainting or collapse.
  • Severe pain in both shoulders with new headache, scalp tenderness, jaw pain while chewing or visual disturbance, particularly after age 50.

Do not attempt to push a dislocated shoulder back into place. Support the arm in the most comfortable position, remove rings if the hand is swelling and arrange safe transport. For suspected heart attack or stroke, call emergency services immediately rather than driving to an orthopaedic appointment.

A Simple Map of the Shoulder

Ball-and-socket joint The humeral head meets the shallow glenoid socket, allowing movement in many directions.
Rotator cuff Four muscles and tendons centre the ball in the socket and help lift and rotate the arm.
Subacromial bursa A thin friction-reducing sac lies between the rotator cuff and the roof of the shoulder.
AC joint The acromioclavicular joint connects the collarbone to the top of the shoulder blade.
Labrum, capsule and ligaments The labrum deepens the socket; capsule and ligaments help guide and stabilise movement.
Biceps and shoulder blade The long biceps tendon crosses the front of the joint while scapular muscles position its moving base.

Where is the Pain Felt?

Front of the shoulder The biceps tendon, upper subscapularis, ball-and-socket joint and surrounding tissues can cause anterior pain. Pain may be worse with lifting, reaching forward or turning the palm upward against resistance.
Outer shoulder or upper arm Rotator cuff–related pain commonly spreads over the deltoid area and may be worse when lifting the arm or lying on that side. The painful area is not necessarily the exact injured structure.
Top of the shoulder The AC joint is considered when pain is localised where the collarbone meets the shoulder and is aggravated by reaching across the chest, lifting or direct pressure.
Back of the shoulder or shoulder blade Posterior cuff, shoulder-blade muscles, the neck and nerves may contribute. Burning, tingling or pain that travels below the elbow makes referred nerve pain more likely.
Diffuse pain with marked stiffness Frozen shoulder, ball-and-socket arthritis and inflammatory conditions can restrict both active and passive movement.
Shoulder-tip pain from elsewhere Heart, lung, diaphragm and upper abdominal conditions may refer pain to the shoulder. Symptoms unrelated to arm movement or accompanied by chest, breathing or abdominal symptoms need broader assessment.

How the Symptoms Began Matters

Fall or collision Fracture, dislocation, AC-joint injury and an acute tendon tear are considered first.
Sudden pull or heavy lift Muscle or tendon strain, biceps injury and an acute-on-chronic rotator cuff tear may occur.
Gradual overhead pain Rotator cuff–related pain and load intolerance commonly develop after increased work, gym or sport.
Progressive stiffness Frozen shoulder, arthritis and less commonly inflammation or infection may reduce movement.
Recurrent slipping or dead arm Instability, previous dislocation, hypermobility or labral injury may be relevant.
Neck movement changes pain Cervical joints or nerves may be a primary or additional source even when the shoulder also feels tender.

Common Causes of Shoulder Pain

Rotator cuff–related shoulder pain A broad clinical group including tendon-related pain and subacromial bursal irritation. Pain is often worse with reaching or lifting and can disturb side-lying. Progressive exercise and load management are usual first treatments.
Rotator cuff tear Partial and full-thickness tears become common with age and may be painless. A sudden injury with immediate weakness has different urgency from an incidental chronic tear found on a scan.
Calcific tendinopathy Calcium deposits within a rotator cuff tendon can be incidental or cause a sudden severe inflammatory flare. X-ray or ultrasound may demonstrate the deposit.
Frozen shoulder Adhesive capsulitis produces pain followed by marked restriction of both active and passive movement, particularly rotation. It is more common with diabetes and thyroid disease but can occur without either.
AC-joint pain Arthritis, a direct fall or ligament sprain can affect the small joint on top of the shoulder. A visible bump after injury may reflect separation of the joint and requires assessment.
Glenohumeral arthritis Osteoarthritis or inflammatory arthritis can cause deep pain, grinding and loss of movement. Symptoms and function matter more than the appearance of an X-ray alone.
Instability and labral injury A previous dislocation, trauma or generalised laxity can produce apprehension, slipping, clicking or a “dead arm.” Labral changes on MRI only matter when they match the history and examination.
Biceps-related pain The long-head biceps tendon and its attachment at the labrum may contribute to front-of-shoulder pain. It often coexists with rotator cuff or joint disease rather than acting alone.
Fracture, dislocation or tendon rupture Trauma can injure the upper humerus, collarbone, shoulder blade or supporting tendons. Deformity, severe swelling, inability to move and circulation or nerve symptoms require urgent assessment.
Neck, nerve or systemic referral Cervical radiculopathy, polymyalgia rheumatica and selected heart, lung or abdominal problems can mimic shoulder disease. Examination must not stop at the painful shoulder when the pattern is atypical.

“Impingement” Does Not Mean the Shoulder is Being Damaged Every Time You Lift

Painful overhead movement is commonly described as impingement, but symptoms reflect an interaction between tendon sensitivity, bursal irritation, strength, load, movement and individual anatomy. The label alone does not prove that a bone spur is cutting the tendon or that surgery is required.

What Happens During an Orthopaedic Assessment?

  • History: onset, injury, exact location, night pain, stiffness, weakness, instability, neck symptoms, fever, work and sport.
  • Observation: posture, bruising, swelling, deformity, muscle wasting and how the shoulder blade moves.
  • Active movement: how far you can lift and rotate the arm yourself, and whether movement is painful, weak or hesitant.
  • Passive movement: how far the examiner can move the relaxed arm, helping distinguish stiffness from pain-limited effort or weakness.
  • Strength: targeted cuff, deltoid, biceps and shoulder-blade muscle testing when safe.
  • Beyond the shoulder: neck, nerves, pulses, chest and other systems when the symptom pattern requires them.

Pain can make a strong tendon appear weak, and several shoulder tests reproduce pain in more than one condition. No single “special test” reliably identifies the exact painful tissue without the rest of the assessment.

Active Movement, Passive Movement and True Weakness

Active movement more limited than passive Pain, tendon dysfunction, nerve weakness or fear may prevent lifting even though the joint can be moved further when relaxed. The cause still needs examination.
Active and passive movement both restricted Frozen shoulder, arthritis, joint inflammation or a mechanical block becomes more likely. The pattern of restriction and X-ray findings help refine the diagnosis.
Sudden weakness after injury An acute rotator cuff tear, fracture, dislocation or nerve injury must be considered. Prompt assessment is important, especially when the person could lift the arm normally before the event.
Gradual painless weakness Chronic cuff disease, nerve problems and muscle wasting are possibilities and deserve assessment even when pain is mild.

Which Tests or Scans Might Be Needed?

X-ray Usually the first image for acute trauma and for chronic shoulder pain when imaging is required. It assesses fracture, dislocation, arthritis, AC-joint change, calcific deposits and some indirect signs of longstanding cuff disease.
Ultrasound Useful after clinical assessment for rotator cuff tendons, the long-head biceps tendon, bursa, calcification and selected image-guided procedures. It is operator dependent and cannot fully assess deep labrum or bone marrow.
MRI Shows rotator cuff, muscles, bone marrow, cartilage, labrum and joint fluid. It is selected when suspected tear, instability, occult fracture, infection, tumour or persistent unexplained symptoms will change treatment.
MR arthrogram Contrast is placed into the joint before MRI for selected labral, instability or post-operative questions. It is invasive and is not the routine first scan for ordinary shoulder pain.
CT Provides detailed bone anatomy for selected fractures, dislocations or complex bony questions. It uses ionising radiation and is not a routine test for gradual rotator cuff–related pain.
Blood tests or aspiration Chosen when infection, inflammatory arthritis, crystal disease or another systemic condition is suspected. Joint fluid may require image-guided sampling. Infection must be excluded before a steroid injection; when sepsis is suspected, sampling and urgent antibiotics are coordinated without avoidable delay.

A Scan Finding Must Match the Clinical Pattern

Tendon wear, partial tears, bursal fluid, AC-joint arthritis and labral changes become common with age and may be painless. X-ray is commonly the initial image; ultrasound or MRI follows the suspected structure and the decision that needs to be made. Scanning every painful shoulder immediately can identify incidental changes without clarifying the pain source.

What Can I Do Safely at First?

  • Keep the shoulder moving gently: for ordinary non-traumatic pain, use a tolerable range several times a day rather than stopping all movement.
  • Modify, do not abandon activity: temporarily reduce heavy, repeated or sustained overhead work that causes a strong or lasting flare.
  • Protect after injury: support a painful arm while arranging assessment, but do not attempt forceful stretching or self-reduction.
  • Cold or warmth: a wrapped cold pack may help a fresh flare; gentle warmth may ease stiffness. Limit either to about 15–20 minutes and protect the skin.
  • Sleep support: avoid lying directly on the painful side and support the forearm on a pillow so the shoulder is not pulled forward.
  • Avoid prolonged sling use: unless prescribed for an injury, extended immobilisation can increase stiffness and muscle loss.
  • Check medicine safety: kidney, stomach, heart or liver disease, pregnancy, allergy and blood thinners affect suitable pain relief.

Seek review if pain is worsening, makes movement very difficult, disturbs sleep persistently, follows trauma, or does not begin to improve with sensible early management. Progressive weakness, numbness or systemic symptoms should not wait.

Treatment Depends on the Cause and Your Goals

Education and load planning Work, gym, sport and sleep positions are adjusted enough to settle an irritable shoulder while maintaining useful activity and preventing unnecessary fear of movement.
Physiotherapy and exercise Range of motion, rotator cuff and shoulder-blade strength, endurance and task-specific control are progressed according to the diagnosis. Frozen shoulder, instability and cuff-related pain require different programmes.
Medicines Suitable pain-relieving or anti-inflammatory medicine may support sleep and exercise. Oral anti-inflammatories need an individual risk assessment and the lowest effective dose for the shortest appropriate time.
Targeted injection A carefully selected corticosteroid injection into the subacromial bursa, AC joint or ball-and-socket joint may provide temporary relief. The target must match the diagnosis; infection must be excluded and repeated injection has risks.
Selected procedures Calcific tendinopathy may occasionally be considered for ultrasound-guided needling or another targeted intervention after assessment. These are not routine steps for all calcification seen on imaging.
Surgery or referral Selected acute major cuff tears, recurrent instability, fractures, dislocations and persistent mechanical problems may require surgery. Advanced arthritis needing joint replacement, complex reconstruction and specialist tumour care are referred to an appropriate higher centre.

Injection does not rebuild a torn tendon or permanently cure arthritis. Surgery is not decided from scan wording alone; the injury pattern, symptoms, function, tissue quality, age, health and goals all matter.

Useful Terms on a Shoulder Report

Rotator cuff tendinopathy Thickening, altered signal or other tendon change. It does not prove that the tendon is the only pain source.
Partial-thickness tear A tear affecting part, but not all, of the tendon thickness. Depth, location, symptoms and strength guide relevance.
Full-thickness tear A defect through the tendon. Acute traumatic tears and chronic degenerative tears have different implications.
Retraction, atrophy or fatty infiltration Signs that help estimate tear chronicity and muscle condition; they may influence specialist treatment options.
Subacromial-subdeltoid bursitis Fluid or thickening in the bursa above the cuff. A small amount may coexist with other changes or be incidental.
Calcific tendinopathy Calcium-containing material within a tendon, commonly supraspinatus. It may or may not explain current pain.
AC-joint osteoarthritis Joint-space and bony change at the collarbone–acromion junction; common with age and not always symptomatic.
Glenohumeral osteoarthritis Cartilage loss, joint-space narrowing and bony change in the main ball-and-socket joint.
Labral tear A change in the rim of the socket. The tear pattern, instability history and clinical findings determine importance.
Effusion or synovitis Extra joint fluid or inflamed lining. Infection, arthritis and other causes are separated clinically.
Hill-Sachs or Bankart lesion Bone or labral injuries associated with shoulder dislocation; their size and instability context guide referral.

Myth vs Fact

Myth All shoulder pain is a rotator cuff tear.
Fact Capsule, bursa, joints, biceps, bone, neck, nerves and referred medical conditions can all cause shoulder-region pain.
Myth A tear on MRI always needs surgery.
Fact Many age-related tears are painless or manageable without surgery. Acute trauma, weakness, tear pattern and goals change the decision.
Myth Complete rest is best until the pain disappears.
Fact Except when an injury requires protection, gentle movement helps avoid stiffness while load is adjusted.
Myth A painful arc proves a tendon is trapped by bone.
Fact Several sensitive shoulder tissues can hurt through part of the movement. A single test does not prove the mechanism.
Myth Frozen shoulder means the joint is permanently frozen.
Fact It can take many months, but pain and movement usually improve. Treatment supports function and manages stiffness safely.
Myth An injection repairs damaged tendon.
Fact Selected injections may reduce pain temporarily; they do not restore tendon structure or replace rehabilitation.

Frequently Asked Questions

When should I arrange an orthopaedic consultation?

Arrange review when pain follows injury, makes movement very difficult, repeatedly disturbs sleep, causes weakness or instability, worsens, or fails to improve steadily with sensible early care. Use urgent care for warning signs.

Should I keep using a painful shoulder?

For ordinary non-traumatic pain, gentle use within tolerance is usually better than complete rest. Temporarily reduce heavy or repeated overhead load that causes a strong or lasting flare. Protect the arm after significant injury.

Why is shoulder pain worse at night?

Side-lying compression, position, reduced daytime distraction and an irritable tendon, bursa, capsule or joint can all contribute. Persistent night pain with fever, weight loss or progressive weakness needs assessment.

Can neck problems cause shoulder pain?

Yes. Neck joints and nerves can refer pain to the shoulder blade, shoulder and arm. Tingling, numbness, weakness or pain below the elbow increases suspicion, but shoulder and neck problems can coexist.

Why can a heart problem feel like shoulder pain?

The brain can interpret pain from the heart as coming from the chest, shoulder, arm, jaw or back. Sudden shoulder or arm pain with chest pressure, sweating, nausea, faintness or breathlessness requires emergency assessment.

Do I need an X-ray?

Not every painful shoulder needs imaging. X-ray is usually the first study after acute trauma and when chronic pain requires imaging because it evaluates bone, alignment, arthritis and calcification.

Is ultrasound or MRI better for the rotator cuff?

Both can assess rotator cuff tendons when performed and interpreted well. Ultrasound is dynamic and accessible; MRI also shows muscle, bone marrow, cartilage and deep joint structures. The suspected problem determines the choice.

Can ultrasound diagnose a labral tear?

Not reliably. The labrum lies deep inside the joint. MRI or an MR arthrogram may be selected after examination when a labral or instability question will change treatment.

Does weakness mean the tendon is torn?

Not necessarily. Pain can inhibit effort, while nerve problems and muscle deconditioning also cause weakness. Sudden marked weakness after injury deserves prompt assessment for a tear, fracture, dislocation or nerve injury.

Should I wear a sling?

A sling can support the arm briefly after selected injuries, but prolonged use without guidance increases stiffness and muscle loss. Follow the plan given after examination and remove it for permitted movement.

Will physiotherapy help before a scan?

Often yes for a non-urgent mechanical pattern. A physiotherapist can guide movement and strength while monitoring progress. Major trauma, deformity, fever, progressive neurological loss or sudden profound weakness needs medical assessment first.

Is a steroid injection a permanent cure?

No. It may provide temporary relief for a carefully selected bursa or joint and help participation in rehabilitation. Infection, diabetes, tendon health, medicines and previous injections affect suitability and risk.

How long does frozen shoulder take to improve?

Recovery is usually measured in months rather than days and varies considerably. Pain and stiffness may change at different rates. The diagnosis should be confirmed because arthritis and other conditions can also restrict movement.

When can I return to gym, swimming or overhead sport?

Return depends on the diagnosis and function. Daily activity should be manageable, range and strength rebuilt, and overhead load progressed gradually without a significant worsening later that day or the next morning.

What if shoulder arthritis becomes severe?

Education, exercise and suitable pain relief remain important. When pain, stiffness and loss of function substantially affect quality of life despite appropriate non-surgical care, referral to a higher centre for joint-replacement assessment may be discussed.
