Shoulder Bursitis Explained

What Is Shoulder Bursitis?

Shoulder bursitis is a common cause of shoulder pain. It occurs when one of the small fluid-filled sacs, called bursae, becomes irritated or inflamed. These bursae normally reduce friction between bones, tendons, and muscles in your shoulder. When inflamed, they can make simple tasks such as reaching, dressing, or lying on the affected side uncomfortable.

Most people feel shoulder bursitis as a dull ache on the outer shoulder, which may spread down the upper arm. The pain often worsens when lifting the arm, reaching overhead, or sleeping on that side.

Common Symptoms of Shoulder Bursitis

Shoulder bursitis symptoms can vary from a mild ache to sharp pain with certain movements. You may notice:

• Pain on the outside of the shoulder, sometimes radiating down the arm
• A “painful arc” when you lift your arm out to the side or overhead
• Night pain, especially when lying on the affected shoulder
• Discomfort with reaching, dressing, hair care, or lifting
• Occasional shoulder weakness due to pain inhibition

Some people also report a feeling of catching or stiffness, particularly when the bursa is irritated alongside rotator cuff related shoulder pain.

What Causes Shoulder Bursitis?

Shoulder bursitis usually develops when the bursa is repeatedly compressed or irritated. Common contributors include:

• Repetitive overhead activities such as swimming, tennis, throwing, or certain work tasks
• Sudden overload, for example, heavy lifting or an awkward reach
• Shoulder impingement, where the tissues under the acromion are pinched during arm elevation
• Rotator cuff tendinopathy or partial tears
• Poor shoulder blade control or posture, which alters the space for the bursa
• Previous shoulder injury or periods of prolonged immobilisation

In some people, general bursitis irritability or age-related changes can make the bursa more sensitive to everyday loads.

How Is Shoulder Bursitis Diagnosed?

A physiotherapist or health professional can usually diagnose shoulder bursitis with a thorough clinical assessment. Your physiotherapist will:

• Ask about when your pain started and what movements aggravate it
• Test your shoulder range of motion to identify a painful arc
• Perform shoulder impingement tests
• Check your neck, shoulder blade, and posture to identify contributing factors

In some cases, imaging may be recommended to clarify the diagnosis or rule out other conditions. Ultrasound or MRI can help distinguish shoulder bursitis from rotator cuff tears, frozen shoulder, or AC joint problems.

How Long Does Shoulder Bursitis Take to Heal?

Recovery time depends on the cause, severity, and how early you start treatment. Mild shoulder bursitis may settle within a few weeks with activity modification and early physiotherapy. More persistent or long-standing cases can take several months to fully resolve, especially if there are associated rotator cuff or shoulder instability issues.

The goal of treatment is not only to calm the irritated bursa but also to improve how your shoulder and shoulder blade move so the problem is less likely to return.

Treatment Options for Shoulder Bursitis

Early Pain Relief and Self-Care

In the early phase, the main aim is to reduce pain and irritation. Your physiotherapist may recommend:

• Relative rest from painful overhead activities
• Short-term use of ice or heat as tolerated
• Gentle range-of-motion exercises within comfort
• Activity modification advice for work, sport, and sleep

Your doctor may also consider anti-inflammatory medication if appropriate for you.

Physiotherapy for Shoulder Bursitis

Physiotherapy plays a key role in both short-term relief and long-term shoulder health. Your shoulder physiotherapy program may include:

• Manual therapy to reduce muscle tension and improve joint mobility
• Targeted exercises to restore shoulder range of motion
• Rotator cuff strengthening exercises to support the bursa
• Scapular control and postural exercises to improve movement patterns
• Education about activity pacing and load management

Recent research suggests that structured exercise and education can improve comfort and function in people with subacromial shoulder pain, including bursitis (Pieters et al., 2020).

When Is a Cortisone Injection Considered?

A subacromial corticosteroid injection may be considered if pain remains high despite an initial period of physiotherapy and activity modification. The aim is to reduce inflammation in the bursa so that you can participate more comfortably in rehabilitation.

Evidence also indicates that corticosteroid injections may offer short-term relief when combined with a graded exercise program (Roddy et al., 2021).

It is still important to address the underlying cause. For example, if your shoulder bursitis developed due to shoulder impingement or rotator cuff overload, your rehabilitation program should focus on correcting these issues.

Is Surgery Ever Needed?

Most people with shoulder bursitis improve without surgery when they follow a well-structured physiotherapy and activity program. Surgical options, such as subacromial decompression, are usually reserved for cases where symptoms remain severe and persistent despite comprehensive non-surgical care and medical review.

How Physiotherapy Helps Your Recovery

Restoring Comfortable Movement

Many people with shoulder bursitis feel stiff or guarded when they try to lift or rotate the arm. Your physiotherapist will guide you through pain-aware movement exercises to restore your range of motion without flaring symptoms.

Consistent exercise progression using criteria-based stages appears helpful for people recovering from shoulder pain conditions, including bursitis (Chepeha et al., 2025).

Improving Strength and Control

Specific strengthening of the rotator cuff and shoulder blade muscles supports the bursa and helps reduce compressive load. Over time, this can make everyday tasks and sport feel more stable and comfortable.

A recent trial reported that targeted movement control and strengthening exercises may support improved outcomes in rotator cuff–related shoulder pain, which often overlaps with bursitis (Dubé et al., 2023).

Optimising Posture and Scapulohumeral Rhythm

The way your shoulder blade and arm move together, known as your scapulohumeral rhythm, can strongly influence the space available for the bursa. Your physiotherapist can coach you through exercises that improve this coordinated movement, which may reduce impingement and recurrent bursitis.

Preventing Recurrence

Once your symptoms improve, your program usually shifts towards long-term prevention. This stage can include:

• Maintenance strength and control exercises
• Gradual return-to-work or sport planning
• Posture and load management strategies

Emerging studies show that progressive strengthening performed within a comfortable range can be effective even when mild pain is present (Cavaggion et al., 2023).

Self-Care Tips and When to Seek Help

Home Strategies That May Help

Alongside your physiotherapy care, you may find the following strategies helpful:

• Use pillow or towel support to improve shoulder comfort at night
• Avoid repetitive overhead lifting during flare-ups where possible
• Use frequent breaks during tasks that load your shoulder
• Follow your prescribed home exercise program

Always check with your physiotherapist or doctor before starting new exercises, especially if your pain is severe or changing quickly.

When Should You See a Physiotherapist or Doctor?

Seek professional assessment if:

• Your shoulder pain is severe or worsening over several days
• You have night pain that regularly disrupts sleep
• You notice marked weakness, instability, or a recent shoulder injury
• Self-care strategies are not improving your symptoms

What to Expect at PhysioWorks

At your appointment, your physiotherapist will assess your shoulder movement, discuss your goals, and outline a clear plan. This may include pain relief strategies, targeted exercises, and load management to help you return to your usual activities.

If needed, your physiotherapist can coordinate with your GP regarding imaging or medical options.

Next Steps

Shoulder bursitis can interfere with daily tasks, work, sleep, and exercise. Early assessment and a structured recovery plan can support you in returning to comfortable, confident movement. This article provides general information only. For personalised advice, please consult a physiotherapist.
