Shoulder bone spurs: Bone Spurs in Shoulder: Causes, Symptoms & Relief

Bone spurs in the shoulder are a common cause of pain, stiffness, and reduced range of motion. Also called shoulder bone spurs or osteophytes, these small bony growths can develop gradually and sometimes go unnoticed until they begin to irritate nearby tendons, muscles, or joints. If you are dealing with shoulder pain, trouble lifting your arm, or a pinching feeling when moving overhead, shoulder bone spurs may be part of the problem.

This guide explains what shoulder bone spurs are, what causes them, how they feel, and the best ways to find relief. For a related overview of bone growths in other areas, see Bone Spurs in Neck: Symptoms, Causes, and Relief.

What Are Bone Spurs in the Shoulder?

Bone spurs are extra pieces of bone that form along the edges of bones, usually where joints or tendons have experienced long-term wear and tear. In the shoulder, they often develop in areas such as:

– The acromion (the bony roof over the shoulder joint)
– The acromioclavicular (AC) joint where the collarbone meets the shoulder blade
– The glenohumeral joint inside the shoulder
– Areas near the rotator cuff tendons

By themselves, shoulder bone spurs are not always painful. The problem happens when they rub against soft tissues or narrow the space where tendons move, causing inflammation and discomfort. In many cases, the spur is only part of the larger issue, and the surrounding irritation is what creates most of the pain.

Shoulder spurs can develop slowly over years. That means a person may not notice the change until daily tasks become uncomfortable. Reaching into a cabinet, fastening a seat belt, or lifting a bag can suddenly feel harder than it used to.

They may also appear alongside other joint changes, including cartilage wear and small areas of inflammation. Because of that, symptoms are not always caused by the spur alone. A doctor may need to look at the whole shoulder to understand what is driving the discomfort.

What Causes Bone Spurs in the Shoulder?

Shoulder bone spurs usually form over time because of repeated stress, inflammation, or joint degeneration. Common causes include:

1. Osteoarthritis

Wear and tear in the shoulder joint can lead to cartilage breakdown. As the body tries to repair itself, bone spurs may form around the joint edges.

When cartilage thins, bones may move less smoothly against each other. This can lead to stiffness, swelling, and changes in the shape of the joint over time. Osteoarthritis is one of the most common reasons the shoulder begins to feel older, tighter, or more limited in motion.

2. Repeated Overuse

Activities that involve repeated overhead motion can place stress on the shoulder. This is common in athletes, painters, manual laborers, and people who frequently lift objects above shoulder level.

Overuse does not have to mean intense training. Even routine movements repeated day after day can irritate the joint. Jobs that require reaching overhead, carrying heavy items, or working with the arms elevated for long periods can place steady pressure on shoulder structures.

3. Aging

Bone spurs become more common with age as joints naturally undergo wear and tear.

As we get older, the cartilage that cushions joints may become thinner and less resilient. The shoulder can then become more vulnerable to small changes in alignment and movement. This is one reason shoulder bone spurs are frequently found in middle-aged and older adults.

4. Rotator Cuff Problems

Tendon inflammation, tears, or impingement in the rotator cuff can contribute to spur formation or make a spur more noticeable. In some cases, the irritation can mimic other causes of shoulder pain and make the problem feel more widespread.

The rotator cuff helps stabilize and move the shoulder. When it becomes inflamed or injured, the joint may not glide as smoothly, which can increase friction in the area. That friction may contribute to pain during lifting, reaching, or rotating the arm.

5. Injury or Trauma

A past shoulder injury, dislocation, or fracture may trigger changes in the joint that later lead to bone spurs.

Even when an injury seems to heal well, the shoulder may not return to its exact previous mechanics. Tiny changes in motion, alignment, or healing can create long-term stress on certain areas and increase the chance of bony overgrowth.

6. AC Joint Degeneration

The AC joint is a frequent site of bone spur development, especially in older adults or people with long-term shoulder strain.

This small joint at the top of the shoulder handles a surprising amount of motion and load. When it wears down, it can produce tenderness at the top of the shoulder and a painful pinch when the arm is raised.

According to the NIAMS overview of osteoarthritis, joint wear and tear can lead to structural changes that affect comfort and movement, which helps explain why this condition often contributes to spur formation.

Other factors may also play a role, including posture, muscle imbalance, and long-term inflammation. Poor shoulder mechanics can place extra stress on one part of the joint, which may make spur-related symptoms more likely to appear or worsen. Over time, a combination of these factors can create a cycle of irritation that keeps the shoulder from moving comfortably.

Sometimes the exact cause is not a single event. Instead, it is the result of several smaller stresses added together. Someone may have mild arthritis, repetitive work demands, and an old injury history, all of which increase the chance that shoulder bone spurs become symptomatic.

Symptoms of Bone Spurs in the Shoulder

Some people have shoulder bone spurs without symptoms. When symptoms do appear, they often depend on the size and location of the spur and whether nearby tissues are affected.

Common symptoms include:

– Shoulder pain, especially when lifting the arm
– Stiffness or reduced shoulder mobility
– Aching or sharp pain during overhead movements
– Weakness in the shoulder or arm
– Clicking, catching, or grinding sensations
– Pain at night, especially when lying on the affected side
– Inflammation or tenderness around the joint

If a bone spur causes shoulder impingement, it may pinch tendons or the bursa, leading to more pain and limited movement. Shoulder bone spurs can also make everyday reaching tasks, like putting on a shirt or reaching a shelf, feel much harder than expected.

Other possible symptoms include pain when lowering the arm, discomfort when rotating the shoulder outward, or a sense that the joint is not moving smoothly. Some people notice that the shoulder feels worse after long periods of activity but improves with rest. Others may experience consistent aching that slowly builds through the day.

In more advanced cases, the shoulder may feel weak because pain limits how much the arm can be used. This is often not true muscle weakness at first, but rather a protective response to discomfort. Still, if the shoulder starts to feel unstable or significantly less functional, it deserves prompt medical attention.

Symptoms can also vary depending on what nearby tissue is irritated. If the bursa becomes inflamed, pain may feel deeper and more diffuse. If the rotator cuff tendon is pinched, the pain may be sharper during specific movements. That variation is one reason shoulder pain can be difficult to identify without an exam.

How Do Bone Spurs in the Shoulder Feel?

People often describe the pain as:

– A dull ache deep in the shoulder
– A sharp pinch when reaching upward or behind the back
– Soreness after activity
– Pain that gets worse with repeated motion

In some cases, the pain may seem to spread into the upper arm, but it usually starts in the shoulder itself. The discomfort may be mild at first and then become more noticeable after exercise, work tasks, or sleeping on the affected side. For some people, shoulder bone spurs feel like a catching sensation rather than constant pain.

People often say the shoulder feels “stuck” for a moment when lifting the arm. Others notice a brief stab of pain when reaching for the back seat of a car, taking off a shirt, or pushing a door open. The pain may ease once the arm is lowered, then return with the next overhead movement.

Because the shoulder is used in so many directions, the symptoms can be frustratingly inconsistent. One movement may feel nearly normal, while another causes a sudden pinch. This pattern is common when the spur is narrowing space near a tendon or bursa rather than causing continuous joint pain.

Night discomfort is also common. If you sleep on the affected side, pressure on the joint can make the pain worse. Some people wake up when they roll onto the shoulder, while others notice soreness that is strongest when they first get out of bed.

How Are Shoulder Bone Spurs Diagnosed?

A healthcare provider usually starts with a physical exam and questions about your symptoms, activity level, and injury history. To confirm the diagnosis, they may order imaging tests such as:

– X-rays to show bone spurs and joint changes
– MRI to check for tendon, ligament, or soft tissue damage
– Ultrasound in some cases to examine the rotator cuff

Because shoulder pain can have many causes, diagnosis helps determine whether the spur is actually causing the symptoms or if another issue is involved. This step matters because treatment for shoulder bone spurs can differ from treatment for arthritis, tendon inflammation, or a rotator cuff tear.

During the exam, the clinician may ask you to lift, rotate, or reach with the arm in different directions. These tests help reveal which movement hurts and whether the pain pattern suggests impingement. They may also press on different parts of the shoulder to check for tenderness at the AC joint or around the rotator cuff.

X-rays are often the first imaging study because they can clearly show bone structure and spur formation. If soft tissue injury is suspected, MRI can provide more detail about tendons and surrounding tissue. Ultrasound may be useful when a quick look at the rotator cuff is needed, especially if pain occurs with specific arm movements.

In some cases, a diagnosis may include more than one condition. For example, a person might have shoulder bone spurs and rotator cuff tendinitis at the same time. That is why a full evaluation is helpful: it can guide a treatment plan that addresses pain, stiffness, inflammation, and any structural damage.

Treatment for Bone Spurs in the Shoulder

Treatment depends on how severe the symptoms are and whether the bone spur is causing inflammation, impingement, or tendon damage.

Many people start with conservative treatment. The goal is to reduce irritation, improve movement, and prevent the shoulder from becoming even stiffer. If symptoms are managed early, surgery may never be needed.

1. Rest and Activity Changes

Reducing activities that worsen pain, especially overhead lifting or repetitive shoulder motion, can help calm irritation. Shoulder bone spurs often feel better when the joint is given time to recover between aggravating activities.

Temporary rest does not mean complete inactivity. Gentle, pain-free movement is often helpful, but the shoulder should not be pushed through sharp pain. Adjusting how you lift, carry, or reach can also reduce strain and allow the irritated tissue to settle down.

2. Ice or Heat

Ice may reduce inflammation and soreness after activity. Heat can help loosen stiff muscles before movement.

Many people find that ice is most useful after a flare-up, while heat is better when the shoulder feels tight or guarded. The right option can depend on whether the main issue is swelling or stiffness. Some people use both at different times of day.

3. Medications

Over-the-counter pain relievers and anti-inflammatory medications may help ease discomfort and swelling. These should be used according to medical advice, especially if you have other health conditions.

If pain is persistent, a clinician may suggest a medication plan tailored to your needs. It is important to consider stomach, kidney, heart, or blood pressure risks before using anti-inflammatory medicines for long periods.

4. Physical Therapy

Physical therapy is often one of the most effective non-surgical treatments. A therapist may recommend exercises to:

– Improve shoulder mobility
– Strengthen the rotator cuff and shoulder blade muscles
– Correct posture
– Reduce impingement during movement

People with shoulder bone spurs often benefit from guided movement because it can improve mechanics without placing extra stress on irritated tissue.

A physical therapist may also work on the upper back and shoulder blade position, since poor posture can increase pressure on the shoulder joint. Strengthening the muscles around the shoulder blade may help the arm move more efficiently and reduce the chance of pinching.

Stretching is usually done carefully and gradually. The goal is not to force the shoulder into painful positions, but to restore smooth motion over time. This often works best when combined with strengthening and activity modification.

5. Corticosteroid Injections

In some cases, a doctor may recommend an injection to reduce inflammation around the affected area. This can provide temporary relief and make physical therapy easier.

Injection treatment may be especially helpful when pain is preventing sleep or keeping the shoulder from participating in rehabilitation. While it may not solve the underlying structural problem, it can create a window of comfort during which recovery exercises are more manageable.

6. Surgery

If symptoms are severe or do not improve with conservative treatment, surgery may be considered. The surgeon may remove the bone spur and repair damaged tissue, especially if there is rotator cuff impingement or a tear. Surgery is usually reserved for cases where shoulder bone spurs continue to interfere with daily function despite other treatment options.

Recovery after surgery depends on what was done during the procedure. Some people need a period of sling use followed by physical therapy. Others gradually regain motion and strength over several weeks or months. The aim is to reduce pain, restore movement, and prevent the joint from staying irritated.

It is worth noting that surgery is not always required just because a spur is visible on imaging. The decision usually depends on symptom severity, response to other treatments, and whether there is damage to the rotator cuff or surrounding tissue.

Home Remedies for Shoulder Bone Spur Relief

If symptoms are mild, these steps may help:

– Avoid painful overhead movements
– Use good posture when sitting and standing
– Apply ice for 15 to 20 minutes after activity
– Try gentle stretching if recommended by a professional
– Sleep on the opposite side or use pillows for support

These measures can reduce irritation, but they do not remove the bone spur itself. Still, many people with shoulder bone spurs find that small daily changes can make pain more manageable.

Additional practical habits may also help. For example, keeping items within easy reach can reduce repeated strain. When lifting, using both arms instead of one can distribute the load more evenly. Taking frequent breaks during repetitive work may also prevent the shoulder from becoming overly inflamed.

Posture is especially important. Slouching can change how the shoulder blade moves and make the joint more crowded. Sitting tall, keeping the chest open, and avoiding rounded shoulders may reduce the chance of a painful pinch during movement.

Some people also benefit from warming up before exercise or physical tasks. Gentle arm circles, light range-of-motion exercises, or approved stretches can prepare the shoulder for activity and lower the risk of sudden irritation. If a movement causes sharp pain, it should not be forced.

Can Bone Spurs in the Shoulder Go Away on Their Own?

No, bone spurs do not usually disappear on their own. However, the pain they cause can often improve with treatment. Many people manage symptoms successfully without surgery by reducing inflammation, improving shoulder mechanics, and avoiding repetitive strain. Even when shoulder bone spurs remain in place, symptoms may become much less noticeable with the right care.

That is an important point: the spur itself may stay the same while the surrounding irritation improves. In other words, the shoulder can feel better even if the bony growth is still present. This is why treatment often focuses on function, pain control, and movement quality rather than trying to “dissolve” the spur.

Some people have spurs for years without major problems. Others develop pain only when the shoulder is stressed by an injury, overuse, or arthritis flare. If the underlying irritation calms down, symptoms may become minimal and easy to manage long term.

When to See a Doctor

You should seek medical care if you have:

– Persistent shoulder pain lasting more than a few weeks
– Difficulty lifting your arm
– Weakness in the shoulder or arm
– Pain that wakes you at night
– Loss of range of motion
– Symptoms after an injury

Early evaluation can help prevent further joint irritation and identify whether the problem is a bone spur, rotator cuff injury, arthritis, or another shoulder condition. If shoulder bone spurs are caught early, treatment may be simpler and recovery may be easier to manage.

You should also get checked sooner if the shoulder looks deformed after an injury, if you cannot move it at all, or if numbness or tingling develops down the arm. Those signs may point to a more serious injury that needs prompt attention.

If pain keeps returning despite rest, that is another good reason to see a clinician. Recurrent symptoms may mean the joint mechanics need correction, or that there is another source of irritation that has not yet been identified.

Can Bone Spurs Cause Frozen Shoulder or Rotator Cuff Problems?

Bone spurs do not directly cause every shoulder problem, but they can contribute to pain and movement limitations. If a spur causes chronic irritation, it may lead to inflammation that affects the rotator cuff or makes it harder to move the shoulder normally. Over time, this can increase the risk of stiffness and more serious shoulder dysfunction.

In some people, the discomfort from shoulder bone spurs also leads to guarded movement, which can make the shoulder feel tighter and less flexible over time.

When movement becomes limited, the shoulder may start to behave as though it is frozen, even if the root issue is pain avoidance rather than a true frozen shoulder diagnosis. Because of this, early treatment matters. Keeping the joint moving within a comfortable range can help reduce stiffness and prevent the shoulder from becoming overly restricted.

Rotator cuff problems are also common alongside spurs. A spur can narrow the space where the tendon moves, which may increase the chance of irritation or a tear over time. On the other hand, an already injured rotator cuff may change shoulder mechanics and make the spur more symptomatic. This overlap is one reason symptoms should be evaluated carefully.

How to Prevent Shoulder Bone Spurs

You cannot always prevent bone spurs, especially those related to aging or arthritis. Still, you may lower your risk by:

– Maintaining good shoulder strength and flexibility
– Using proper form during sports or lifting
– Avoiding repeated overload of the shoulder
– Treating shoulder injuries early
– Managing arthritis and inflammation with medical guidance

Healthy movement habits can help protect the shoulder joint and may reduce the chance that shoulder bone spurs become painful later on.

It can also help to vary your activities when possible. Repeating the same motion for long periods can overload the shoulder, so changing positions and using the correct equipment may reduce strain. For athletes, technique and warm-up routines matter. For workers, ergonomics and pacing can make a meaningful difference.

Strong upper-back and shoulder muscles support joint function, which may help reduce abnormal stress on the AC joint and rotator cuff. Regular exercise, when done safely, may support long-term shoulder health. If you have a past injury or ongoing arthritis, staying in touch with a healthcare provider can help you adjust activity before symptoms worsen.

Related Conditions That Can Feel Similar

Shoulder bone spurs are only one possible cause of shoulder pain. Other conditions can create similar symptoms, which is why a proper evaluation is so important.

• Rotator cuff tendinitis or tear: often causes pain with lifting or reaching overhead.
• Shoulder bursitis: may cause tenderness, swelling, and pain during motion.
• Arthritis in the shoulder or AC joint: can lead to stiffness and aching.
• Frozen shoulder: usually causes a gradual loss of motion and significant stiffness.
• Neck problems: sometimes refer pain into the shoulder and upper arm.

Because these problems can overlap, symptoms alone may not be enough to tell them apart. Imaging and a physical exam can help identify whether a spur is the main issue or whether another shoulder condition needs attention.

Living With Shoulder Bone Spurs

Many people are able to live well with shoulder bone spurs once they understand what triggers their symptoms. That often means learning which movements to limit, how to support the shoulder at night, and when to use rest versus gentle activity.

Daily self-care can make a real difference. For example, a person who works at a desk may need to adjust chair height and monitor position so the shoulders are not hunched forward all day. Someone who exercises may need to modify overhead presses or switch to less painful movements while healing.

Managing expectations is also important. Improvement is often gradual rather than instant. With consistent treatment, many people notice less pain, better motion, and more confidence using the shoulder again. The key is to treat the joint early, avoid repeated flare-ups, and follow a plan that supports long-term function.

Key Takeaway

Bone spurs in the shoulder are bony growths that can develop from aging, arthritis, injury, or repetitive strain. They may cause pain, stiffness, weakness, and impingement, especially during overhead movement. While bone spurs do not usually go away on their own, many people find relief with rest, medication, physical therapy, and other non-surgical treatments. If shoulder pain is persistent or limiting your movement, getting evaluated early can help you find the right treatment and prevent further damage. Shoulder bone spurs are often manageable, and the right care can help you stay active with less discomfort.
