What you're feeling

You may notice clicking, popping, or a grinding sensation in your shoulder. This often happens when the joint feels loose or unstable. The sound might come from the front or back of the shoulder, depending on which way it slips. You might feel a sudden shift or a "slipping" sensation when you move your arm.

Pain usually follows these episodes. It can feel deep inside the joint or spread down your upper arm. You may feel sharp pain when you lift your arm overhead or reach behind your back. Simple tasks like putting on a jacket, reaching for a seatbelt, or lifting a grocery bag can become difficult. Your shoulder might feel weak or like it might give way during these movements.

Symptoms often flare after activity. You might feel soreness the next morning or after sleeping in certain positions. Night pain is common if you sleep on the affected side. The discomfort can make it hard to find a comfortable resting position. You may also feel stiffness after keeping your arm still for a long time, such as during a long drive or at a desk.

In some cases, the shoulder dislocates completely. This is a sudden, painful event where the ball of the upper arm bone pops out of the socket. It can happen during sports or after a fall. Even if it pops back in on its own, the area may remain swollen and tender for days. You might feel anxious about using that arm again, fearing another slip.

If you have multidirectional instability, the shoulder may feel loose in multiple directions. You might notice clicking when raising your arm to the side or behind you. This can affect daily activities like washing your hair or reaching for items on a high shelf. The feeling of instability can be frustrating and limiting.

We understand that these symptoms can disrupt your daily life. A thorough clinical exam is the most important factor in determining the cause of your symptoms. We will look at your specific movement patterns and stability to guide your treatment.

What's actually happening

Your shoulder is a ball-and-socket joint. The ball sits in a shallow cup. A ring of cartilage, called the labrum, lines that cup. Think of the labrum like a gasket or a shock absorber. It deepens the socket. This helps keep the ball centered. It minimizes the gap between the ball and the socket. Without it, the joint is loose.

Clicking or popping often means this gasket is damaged. The labrum may tear. This happens when the shoulder dislocates. The ball slips out of place. It can also happen from wear and tear. When the labrum is injured, it cannot hold the ball securely. The joint becomes unstable. You might feel a catch or a pop. This is the ball shifting in the socket.

Sometimes, the problem is not just the soft tissue. The bone itself may be worn down. The socket can become too shallow. The labrum cannot compensate for this loss of bone depth. The joint loses its natural shape. This makes instability more likely. You may feel like the shoulder is slipping again.

In some cases, the ligaments that hold the shoulder together are torn. These are like strong ropes. If they detach from the bone, the shoulder loses support. This can happen after a dislocation. It can also happen with repeated injuries. The shoulder feels loose and unpredictable.

Your surgeon will examine your shoulder closely. They will check how stable it is. Imaging helps, but the physical exam is key. It shows what is actually moving wrong. This guides the treatment plan. The goal is to restore stability. This stops the clicking and popping. It helps you use your shoulder safely again.

What we can do about it

At Mater Private Hospital Rockhampton, Dr Kieran Hirpara approaches shoulder instability by matching the treatment to the cause of your symptoms. We start with the least invasive options and move to surgery only when necessary. Your journey begins with a clear diagnosis based on your history, examination, and imaging.

For many patients, especially those with first-time or mild instability, self-management and physiotherapy are the best first step. You can try changing activities that trigger clicking or popping. A physiotherapist will guide you through exercises to strengthen the muscles around your shoulder blade and arm. This helps stabilize the joint and improves your range of motion. We usually recommend giving this approach at least several weeks to show results. For military personnel or athletes with recurrent dislocations, combining kinesio taping with conventional rehabilitation can lead to significant improvements in function compared to exercise alone.

If pain persists, medical management can help control symptoms. Your surgeon may discuss pain medication or anti-inflammatory drugs to reduce swelling and discomfort. In some cases, we consider injections. Cortisone injections can calm inflammation for a few weeks to months, helping you participate in therapy. Hyaluronic acid or platelet-rich plasma (PRP) injections are sometimes used to support joint health, though their long-term effects vary. These options do not fix structural damage but can make daily life more comfortable while your body heals or while you build strength.

Surgery is considered when conservative care has not given enough improvement, or if you have a structural problem like a large bone loss or recurrent dislocations that affect your quality of life. For acute injuries with significant bone damage, we may recommend surgery sooner rather than later. The operation aims to repair torn ligaments or restore bone structure to prevent the shoulder from slipping out of place. We discuss the specific surgical plan with you based on your unique anatomy and goals. For example, arthroscopic Bankart repair is common for anterior instability, while bone block procedures may be needed for severe bone loss. We view this as a shared decision, weighing the risks and benefits to help you return to the activities you love.

What to expect

Your shoulder symptoms often come and go. Many people find that their shoulder feels unstable or clicks during certain movements. For some, this settles with rest and careful movement. For others, the feeling of slipping or catching persists. If you have had a first-time dislocation, your surgeon may suggest non-surgical care first, especially if you are active in sports. This approach helps you stay in the game while your shoulder heals.

If surgery is needed, the outlook depends on the type of damage. For common front-of-shoulder instability, both keyhole (arthroscopic) and open surgery offer similar results in preventing future dislocations. However, if you have significant bone loss or specific types of bone dents, keyhole repair alone may not be enough. In these cases, the risk of the shoulder slipping again is high. This can lead to poorer long-term satisfaction over ten years. Your surgeon will look at your age, the shape of the tear, and its location to predict your risk of recurrence.

For complex cases, such as multidirectional instability or connective tissue conditions like Ehlers-Danlos syndrome, specialised procedures using tissue grafts can provide stability and improve function. In severe, end-stage cases where the joint is worn out, options like joint fusion or reverse replacement are available. These are considered when other treatments have failed.

Recovery is a gradual process. You will likely feel stiffness and soreness for several weeks. Physical therapy is essential to regain strength and control. While many patients return to their daily activities and sports, the timeline varies. Some factors, like the specific injury pattern or previous surgeries, can influence how quickly you recover. It is important to have realistic expectations. Not every shoulder returns to its pre-injury state immediately, and some people may continue to experience occasional clicking or popping even after successful treatment. Your surgeon will guide you through each stage to ensure the best possible outcome for your specific situation.

When to see someone

See your GP if your shoulder pain does not improve with rest. Ask for a specialist review if you feel weakness, instability, or if the joint locks or gives way. Symptoms that interfere with sleep or work also warrant a check-up. Sudden worsening needs attention. A thorough clinical exam is the most important factor in deciding if surgery is needed for your shoulder instability. Early recognition helps ensure the best functional outcome. Do not ignore persistent clicking or popping if it affects your daily life.

Advanced reading: the deeper science (optional)

This section goes further than you need for your own treatment decisions. Clicking and popping in the shoulder is worth the extra reading because it is a symptom rather than a diagnosis — and because the single most useful thing to establish is whether the noise comes with a sense that the joint is moving where it should not.

Noise on its own is usually not the problem

A shoulder that clicks, snaps or grinds without pain, without weakness and without a feeling of giving way is common and generally does not indicate damage. Tendons move over bony ridges, the capsule folds and unfolds, and gas can move within the joint fluid. None of that requires treatment.

The reason this matters is that a noise is alarming out of proportion to its significance, and imaging a painless clicking shoulder will frequently find something — an age-typical labral fray, a partial cuff change — that then gets blamed for it. The rotator cuff literature makes this concrete: cuff abnormalities are common enough in people without symptoms to be considered a feature of normal ageing, which makes it genuinely difficult to know whether a finding is new or causative [1].

The question that separates the groups

What changes the assessment is whether the noise is accompanied by a sense of the joint shifting, slipping or giving way — apprehension when the arm is raised and rotated outwards, an episode of the shoulder coming out, or a persistent feeling of looseness.

That combination points towards instability, which is a structural problem with its own evidence, its own decision points and its own treatments — the balance of bone loss against soft tissue, whether a Hill-Sachs lesion engages, and the choice between repair, remplissage and bone transfer. Those are covered in depth on the shoulder instability page rather than repeated here.

The second combination worth recognising is noise with true weakness or visible wasting, which points away from the joint surface entirely and towards the rotator cuff or a nerve problem.

Why painless clicking after a stabilisation is different again

If you have had instability surgery, a shoulder that clicks is a common source of worry. Worth knowing: arthritic change following arthroscopic Bankart repair is present in 60% of shoulders for any change and 28% for moderate-to-severe change — and it is generally asymptomatic, with no significant correlation identified with the established risk factors [2].

So a mechanical noise in a previously stabilised shoulder, without instability symptoms, is more often a reflection of a joint that has been through something than a sign of failure.

What is actually worth reporting

Three features change the assessment and are worth mentioning specifically: a sense of the joint moving or giving way; genuine weakness rather than pain-limited effort; and locking or catching that physically blocks movement rather than merely making a sound.

Clicking without any of those, in a shoulder that works, is the situation in which the most useful intervention is an explanation rather than an investigation.

Using Creative Commons Public Licenses

Creative Commons public licenses provide a standard set of terms and conditions that creators and other rights holders may use to share original works of authorship and other material subject to copyright and certain other rights specified in the public license below. The following considerations are for informational purposes only, are not exhaustive, and do not form part of our licenses.

Considerations for licensors: Our public licenses are intended for use by those authorized to give the public permission to use material in ways otherwise restricted by copyright and certain other rights. Our licenses are irrevocable. Licensors should read and understand the terms and conditions of the license they choose before applying it. Licensors should also secure all rights necessary before applying our licenses so that the public can reuse the material as expected. Licensors should clearly mark any material not subject to the license. This includes other CC- licensed material, or material used under an exception or limitation to copyright.

Considerations for the public: By using one of our public licenses, a licensor grants the public permission to use the licensed material under specified terms and conditions. If the licensor's permission is not necessary for any reason--for example, because of any applicable exception or limitation to copyright--then that use is not regulated by the license. Our licenses grant only permissions under copyright and certain other rights that a licensor has authority to grant. Use of the licensed material may still be restricted for other reasons, including because others have copyright or other rights in the material. A licensor may make special requests, such as asking that all changes be marked or described. Although not required by our licenses, you are encouraged to respect those requests where reasonable.

Creative Commons Attribution-NonCommercial 4.0 International Public License

By exercising the Licensed Rights (defined below), You accept and agree to be bound by the terms and conditions of this Creative Commons Attribution-NonCommercial 4.0 International Public License ("Public License"). To the extent this Public License may be interpreted as a contract, You are granted the Licensed Rights in consideration of Your acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and conditions.

Section 1 -- Definitions.

a. Adapted Material means material subject to Copyright and Similar Rights that is derived from or based upon the Licensed Material and in which the Licensed Material is translated, altered, arranged, transformed, or otherwise modified in a manner requiring permission under the Copyright and Similar Rights held by the Licensor. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image.

b. Adapter's License means the license You apply to Your Copyright and Similar Rights in Your contributions to Adapted Material in accordance with the terms and conditions of this Public License.

c. Copyright and Similar Rights means copyright and/or similar rights closely related to copyright including, without limitation, performance, broadcast, sound recording, and Sui Generis Database Rights, without regard to how the rights are labeled or categorized. For purposes of this Public License, the rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.

d. Effective Technological Measures means those measures that, in the absence of proper authority, may not be circumvented under laws fulfilling obligations under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, and/or similar international agreements.

e. Exceptions and Limitations means fair use, fair dealing, and/or any other exception or limitation to Copyright and Similar Rights that applies to Your use of the Licensed Material.

f. Licensed Material means the artistic or literary work, database, or other material to which the Licensor applied this Public License.

g. Licensed Rights means the rights granted to You subject to the terms and conditions of this Public License, which are limited to all Copyright and Similar Rights that apply to Your use of the Licensed Material and that the Licensor has authority to license.

h. Licensor means the individual(s) or entity(ies) granting rights under this Public License.

i. NonCommercial means not primarily intended for or directed towards commercial advantage or monetary compensation. For purposes of this Public License, the exchange of the Licensed Material for other material subject to Copyright and Similar Rights by digital file-sharing or similar means is NonCommercial provided there is no payment of monetary compensation in connection with the exchange.

j. Share means to provide material to the public by any means or process that requires permission under the Licensed Rights, such as reproduction, public display, public performance, distribution, dissemination, communication, or importation, and to make material available to the public including in ways that members of the public may access the material from a place and at a time individually chosen by them.

k. Sui Generis Database Rights means rights other than copyright resulting from Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, as amended and/or succeeded, as well as other essentially equivalent rights anywhere in the world.

l. You means the individual or entity exercising the Licensed Rights under this Public License. Your has a corresponding meaning.

Section 2 -- Scope.

a. License grant.

1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:

a. reproduce and Share the Licensed Material, in whole or in part, for NonCommercial purposes only; and

b. produce, reproduce, and Share Adapted Material for NonCommercial purposes only.

2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.

3. Term. The term of this Public License is specified in Section 6(a).

4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a) (4) never produces Adapted Material.

5. Downstream recipients.

a. Offer from the Licensor -- Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.

b. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

b. Other rights.

1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

2. Patent and trademark rights are not licensed under this Public License.

3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the following conditions.

a. Attribution.

1. If You Share the Licensed Material (including in modified form), You must:

a. retain the following if it is supplied by the Licensor with the Licensed Material:

i. identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner requested by the Licensor (including by pseudonym if designated);

ii. a copyright notice;

iii. a notice that refers to this Public License;

iv. a notice that refers to the disclaimer of warranties;

v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;

b. indicate if You modified the Licensed Material and retain an indication of any previous modifications; and

c. indicate the Licensed Material is licensed under this Public License, and include the text of, or the URI or hyperlink to, this Public License.

2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material. For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information.

3. If requested by the Licensor, You must remove any of the information required by Section 3(a)(1)(A) to the extent reasonably practicable.

4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 -- Other Terms and Conditions.

a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

b. Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License.

Section 8 -- Interpretation.

a. For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under this Public License.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
