Why Does My Shoulder Click?

Short answer: A shoulder can click, pop, crack or grind without being damaged. Normal joint pressure changes and movement of tendons, muscles or the shoulder blade may create sound. Clicking deserves more attention when it begins after an injury or occurs with pain, weakness, true locking, swelling, loss of movement, or a feeling that the shoulder is slipping out.

The sound itself rarely identifies the structure. A click near the collarbone during a push-up, a deep clunk during a throw and a rough grinding sensation in a stiff older shoulder create different clinical questions. Assessment should focus on where the sensation occurs, which movement reproduces it and what accompanies it.

When shoulder clicking needs urgent assessment

Seek urgent medical assessment if:

• the shoulder looks deformed or out of position after a fall, collision or forceful movement;
• the arm is stuck in one position or you suspect a dislocation;
• a new pop is followed by inability to lift the arm, marked weakness, swelling or substantial bruising;
• the shoulder is hot, red or rapidly swelling, especially with fever or feeling seriously unwell;
• the arm or hand becomes cold, pale or blue, or develops sudden substantial swelling;
• there is new or rapidly worsening weakness, extensive numbness, loss of coordination or difficulty walking;
• shoulder or arm discomfort occurs with chest pressure, breathlessness, sweating, nausea or faintness.

Do not repeatedly test or try to relocate a visibly deformed shoulder yourself. For a life-threatening emergency in Singapore, call SCDF 995.^[1]

First question: is the clicking painful?

Painless and occasional

An occasional click without pain, swelling, weakness, instability or loss of function is often less concerning. It may reflect movement between joint surfaces or soft tissues. If the shoulder works normally and the sound is not changing, treatment may not be necessary.

Painful or function-limiting

Clicking associated with pain, weakness, reduced range, catching, locking or a slipping sensation needs closer assessment. The combination of symptoms provides more useful information than loudness alone.

New after trauma

A pop during a fall, heavy lift, forceful pull or overhead action may accompany a tendon, labral, ligament or bone injury. Immediate weakness, deformity or inability to continue the activity increases the need for timely assessment.

What do patients mean by clicking, popping and grinding?

• Click: a brief, discrete sound or sensation during a repeatable part of movement.
• Pop: a more sudden sound, sometimes associated with an injury or a joint shifting.
• Clunk: a deeper movement sensation that may be described with instability or labral symptoms.
• Grinding or crepitus: a rough or crackling sensation through part of the range.
• Snapping: a tendon or other soft tissue appears to move abruptly over a nearby structure.
• True locking: the joint becomes mechanically stuck and cannot continue through its usual movement.

Patients use these words differently. Demonstrating the exact movement is often more informative than the label.

1. Normal joint or soft-tissue movement

The shoulder complex contains several moving interfaces. Pressure changes within a joint and soft tissues gliding over one another may produce sound. A painless click that has been present for years and does not affect function may represent normal variation.

Trying to eliminate every sound can create unnecessary fear and repeated self-testing. The aim is comfortable, confident function—not a perfectly silent shoulder.

2. Shoulder-blade movement

The shoulder blade glides over the rib cage during arm movement. Muscles, bursae and the shape of the chest wall influence this motion. Some people feel rubbing, snapping or crackling around the inner border or lower part of the shoulder blade.

This scapulothoracic sound may be painless. When painful, assessment may consider recent load, muscle control, local tenderness, previous injury and less common bony causes. Simply being told to hold the shoulders “back and down” all day is not a diagnosis or a complete treatment plan.

3. Rotator cuff or bursa

The rotator cuff tendons and nearby bursa move as the arm elevates. A tendon-related presentation may cause pain, weakness and sometimes a catching or crackling sensation. A traumatic tear may cause a sudden pop and immediate weakness, while a degenerative tear may develop gradually or exist without symptoms.

AAOS notes that rotator cuff tears may produce crepitus with certain shoulder movements as well as pain and weakness.^[2] Clicking alone does not establish a tear, and many rotator cuff presentations do not click.

4. Biceps tendon

The long head of the biceps tendon passes through the front of the shoulder. Irritation or instability of this tendon may cause front-of-shoulder pain and a snapping sensation during rotation or elevation. It can coexist with rotator cuff or labral pathology.

A clinician may try to reproduce the symptom with specific movements and assess the tendon, rotator cuff and stability together. Ultrasound can provide a dynamic view of selected tendon movements when clinically relevant.

5. Labral symptoms

The labrum is a rim of tissue around the shoulder socket. It contributes to stability and serves as an attachment point for ligaments and part of the biceps tendon. A labral injury can follow a fall, forceful pulling, dislocation or repeated overhead activity.

AAOS lists locking, popping, catching or grinding among possible symptoms of a SLAP tear, along with pain, reduced strength and a feeling that the shoulder may pop out.^[3] These symptoms overlap with other shoulder conditions, and age-related labral changes can appear on imaging without being the cause of pain.

6. Shoulder instability

Instability may develop after a dislocation or with repeated overhead loading and joint laxity. Patients may describe slipping, giving way, a clunk or apprehension when the arm is elevated and rotated. Some have a sense that the shoulder is not centred even if it has never fully dislocated.

AAOS describes recurrent giving way and a persistent loose or slipping sensation among features of chronic shoulder instability.^[4] The direction of instability, traumatic history and presence of bone or labral injury influence treatment.

7. Arthritis or joint-surface changes

Arthritis of the main shoulder joint may cause deep pain, stiffness, reduced active and passive movement and grinding. Acromioclavicular-joint arthritis may cause pain and clicking near the upper shoulder during pressing, cross-body movement or end-range elevation.

AAOS notes that grinding, clicking or cracking can occur with shoulder arthritis.^[5] Imaging findings must still be matched to symptoms: joint changes may exist without explaining every sound or pain episode.

8. Previous injury or surgery

A healed fracture, altered joint alignment, scar tissue or postoperative changes may alter how the shoulder moves and sounds. New painful clicking after surgery should be discussed with the treating team, particularly when accompanied by swelling, weakness, instability or loss of previously regained function.

9. Neck-related symptoms

A click generated by the shoulder is different from pain referred from the neck, but both can coexist. Tingling, numbness, symptoms below the elbow, pain influenced by neck movement or neurological weakness make cervical and nerve assessment relevant.

Does clicking mean bone is rubbing on bone?

No. There are many possible sources of shoulder noise, most of which do not mean that bare bone surfaces are rubbing together. Even when arthritis is present, a sound cannot grade joint damage.

Terms such as “wear and tear” can also create unnecessary fear. The clinical focus should be pain, movement, strength, stability, function and progression rather than sound alone.

Should you keep making the shoulder click?

Repeatedly provoking a painless click is not necessarily harmful, but constant testing can irritate tissues or increase worry. Do not repeatedly force a painful clunk, an unstable position or a movement associated with locking. Modify it and arrange assessment if it persists.

How a clicking shoulder is assessed

The history may clarify:

• where the click is felt—front, upper shoulder, deep joint or shoulder blade;
• the exact movement, load, speed and arm position;
• whether the click is painful and whether pain comes before, during or afterwards;
• trauma, dislocation or a sudden pulling event;
• weakness, stiffness, swelling, catching, true locking or instability;
• changes in gym training, sport, work or repetitive overhead activity;
• night symptoms and loss of daily function;
• neck pain, tingling or numbness;
• previous imaging, rehabilitation, injection or surgery.

Examination may compare active and passive range, locate tenderness, test rotator cuff and upper-limb strength, observe the shoulder blade and assess stability. The clinician may reproduce the relevant task and examine the neck and nerves when indicated.

No single clicking sound or provocative test confirms a labral tear, tendon injury or instability. Findings are interpreted together with the history and response to load.

When may an X-ray be considered?

X-ray may be appropriate after trauma or when fracture, dislocation, arthritis, calcification, joint alignment or another bone-related cause is suspected. For chronic shoulder pain, the American College of Radiology rates shoulder radiography as usually appropriate initial imaging.^[6]

X-rays do not directly show the labrum and cannot fully evaluate the rotator cuff or biceps tendon. A normal X-ray does not exclude every painful cause of clicking.

When may ultrasound be considered?

Ultrasound can assess the rotator cuff, biceps tendon, bursa and calcific deposits. Its dynamic capability may help when snapping or tendon movement can be reproduced during the scan. It can also guide selected procedures.

Ultrasound is operator dependent and is not usually the main test for suspected labral pathology or internal joint instability.

When may MRI or MR arthrography be considered?

MRI can assess the rotator cuff, labrum, biceps anchor, cartilage, bone marrow and other soft tissues. It may be considered when painful clicking persists after appropriate care, follows trauma, accompanies weakness or instability, or when a treatment decision requires structural detail.

For suspected labral pathology or instability after normal or inconclusive radiographs, the ACR rates MRI without contrast and MR arthrography as usually appropriate options.^[6] MR arthrography involves injecting contrast into the joint before MRI and is used for selected questions rather than every clicking shoulder.

Imaging can also reveal changes unrelated to symptoms. The scan should answer a focused question and be interpreted alongside examination rather than used to label every sound as damage.

What treatment may help?

No treatment may be needed for painless clicking

If the shoulder is pain-free, strong, stable and fully functional, reassurance and observation may be appropriate. Treatment should not be driven by noise alone.

Temporary load modification

Reduce the specific movement, range, speed or load that repeatedly causes painful clicking. Avoid complete long-term rest unless an injury requires protection. Track the response over the following 24 hours.

Progressive rehabilitation

Depending on the diagnosis, rehabilitation may develop rotator cuff and shoulder-blade muscle capacity, joint control, range, confidence and task-specific tolerance. Instability rehabilitation may emphasise dynamic control; arthritis or stiffness requires a different balance of mobility and strength.

Medication or selected symptom-relief care

Appropriate medication, manual care or physical modalities may help pain for selected patients. Suitability depends on the diagnosis, other medicines and medical conditions. Passive care may support movement but does not automatically correct instability or rebuild load capacity.

Injection or surgery

An injection is not a treatment for sound alone. It may be considered for a selected painful diagnosis after discussion of risks, expected benefit and alternatives. Surgical referral may be appropriate for recurrent traumatic instability, selected labral injuries, functionally significant tears, advanced arthritis or mechanical problems that remain disabling after suitable nonsurgical care.

Pain, attention and confidence can change the experience

A new sound can cause understandable worry and lead a patient to monitor every movement. Heightened attention, poor sleep, fear of damage and previous injury experiences can increase distress and reduce use of the arm. A biopsychosocial approach addresses these factors alongside the suspected tissue or joint source.

This does not mean painful clicking is imaginary. It means the aim is to identify clinically meaningful features, restore safe function and avoid allowing harmless noise to dominate activity.

Patient-specific scenarios

If the shoulder clicks but does not hurt

If movement, strength and function remain normal, monitor rather than repeatedly testing it. Arrange assessment if pain, swelling, instability, locking or weakness develops.

If a pop occurred during a heavy lift or fall

Stop the provoking activity and assess function. Deformity, inability to lift the arm, major weakness or swelling needs prompt medical review. Imaging selection depends on whether fracture, dislocation, tendon or labral injury is suspected.

If clicking occurs during bench press or overhead exercise

Review load, grip, range, speed, fatigue and recent training changes. Temporarily modify the painful component, then rebuild capacity progressively. A painless sound does not necessarily require abandoning the exercise.

If the shoulder feels as if it slips or gives way

Instability becomes more relevant, especially after a previous dislocation. Avoid repeatedly provoking the apprehensive position and arrange assessment of stability, strength and possible associated injury.

If you have already tried physiotherapy

Review whether treatment targeted the likely source, progressed towards the clicking task and measured pain, strength, stability and function. Persistent painful clicking with catching or instability may justify diagnostic reassessment and selected imaging rather than repeating the same exercises.

If you prefer a passive treatment

A passive option may help pain temporarily but should not be presented as a way to “put the shoulder back” without a diagnosis. When weakness, control or load tolerance contributes, an achievable active component remains important.

If you need to return to work or sport quickly

Define the exact reach, load, speed and repetition required. Short-term modification may allow participation while the shoulder is assessed and progressively reloaded. A new traumatic pop with weakness should not be masked simply to meet a deadline.

If you want an MRI because the click feels deep

Depth of sensation does not determine the scan. MRI or MR arthrography may be useful when a labral, tendon or instability question would change management. X-ray or ultrasound may be more appropriate for other suspected causes.

Integrated doctor and physiotherapy management

The Pain Relief Clinic has in-house physiotherapists for integrated management with the licensed medical doctor. Where physiotherapy is clinically appropriate, this can align the differential diagnosis, movement and stability assessment, progressive loading, return-to-work or sport planning, and decisions about imaging, medication, selected procedures or referral. Physiotherapists practising in Singapore are regulated by the Allied Health Professions Council, which maintains a public register.^[7]

The clinic can assist with clinically appropriate referrals and supporting paperwork for insurance claims. Coverage, required documents, pre-authorisation and reimbursement depend on the patient’s policy and insurer. A referral, form or medical report does not guarantee approval or payment.

Frequently asked questions

Is shoulder clicking normal?

It can be. Occasional painless clicking without weakness, swelling, instability or functional loss is often less concerning. New painful clicking deserves assessment.

Does clicking mean I have a labral tear?

No. Labral problems can click, but tendons, the shoulder blade, arthritis, instability and normal joint movement can also create sounds. A labral diagnosis requires more than a click.

Can a rotator cuff tear cause clicking?

It can be associated with crepitus, pain and weakness, but clicking alone does not establish a tear. Sudden weakness after trauma is more clinically important than sound by itself.

Should I stop exercising if my shoulder clicks?

Not automatically if the sound is painless and function is normal. Modify or stop a movement that produces pain, instability, locking or worsening symptoms, and seek assessment if these persist.

Can physiotherapy stop the clicking?

Rehabilitation may reduce painful clicking when strength, control or load tolerance contributes. A harmless sound may remain even when the shoulder is functioning well; silence should not be the only outcome.

Do I need an MRI?

Not for every click. MRI or MR arthrography may be considered when symptoms suggest a labral, tendon or instability problem and the result could change treatment. The history and examination guide the choice.

Key points

• Shoulder clicking is a symptom, not a diagnosis.
• Painless clicking with normal function is often less concerning.
• Pain, weakness, true locking, instability, swelling and trauma make clicking more significant.
• X-ray, ultrasound, MRI and MR arthrography answer different questions.
• Treatment should address the diagnosed problem and functional goal, not sound alone.
• Progressive rehabilitation should be matched to the patient’s movement and load demands.
