What Is Shoulder Bursitis?
A bursa is a small, fluid-filled sac that sits between tendons, bones, and muscles to reduce friction and allow smooth movement. In the shoulder, the most significant is the subacromial bursa, nestled between the rotator cuff tendons and the underside of the acromion.
When this bursa becomes inflamed — through repetitive overhead activity, direct trauma, postural loading, or underlying inflammatory conditions — the result is subacromial bursitis: pain, swelling, and restricted function that can significantly limit everyday activities.
Bursitis in the shoulder is broadly classified into three types:
Chronic bursitis — the most common; develops gradually from repetitive microtrauma or sustained postural load
Acute/traumatic bursitis — sudden onset following an injury or fall
Septic (infected) bursitis — rare but serious; requires a different management pathway entirely
Why Does It Happen?
Common contributing factors include:
Repetitive overhead movements (sport, lifting, occupational loading)
Sustained sedentary postures — particularly with the shoulder internally rotated and drawn forward
Poor scapular mechanics (scapular dyskinesis — especially in younger patients)
Underlying inflammatory conditions: rheumatoid arthritis, gout, diabetes
Rotator cuff pathology, which often coexists and contributes to bursal irritation
Direct trauma or falls onto the shoulder
An important anatomical note: internal rotation of the shoulder compresses the subacromial space, which is why chronically rounded, forward-drawn shoulder posture is such a significant driver. This is frequently exacerbated by prolonged laptop use, driving posture, and repetitive overhead loading.
Signs and Symptoms
The classic presentation of subacromial bursitis includes:
Anterolateral shoulder pain, typically felt at the outer shoulder and upper arm
Painful arc on abduction — pain that begins at approximately 70–90° and eases beyond 120°
Night pain
Difficulty sleeping on the affected side
Overhead movement restriction — unable to complete normal dressing activities, reaching, or lifting
Tingling or referral down the arm — pain from the bursa can refer as far as the wrist and hand
Tenderness on palpation at the anterolateral shoulder below the acromion
Warmth or bogginess at the site (erythema is generally NOT present in non-septic bursitis)
Additional Fact: In septic bursitis, the picture differs: expect fever, pronounced local warmth and redness, peribursal cellulitis, and pain more severe than typical inflammatory bursitis.A key clinical takeaway: joint motion is typically preserved in septic bursitis, whereas mechanical/inflammatory bursitis is associated with limited range of motion.
Management
The vast majority of shoulder bursitis cases resolve with conservative care. Osteopathic management has shown to be of benefit through a holistic approach to management, in which a wide range of manual therapy, rehab advce and alterations to common contributing factors are addressed. The cornerstone of treatment is non-operative management, centred on structured rehabilitation, activity modification, and load management.
Evidence strongly supports the following conservative measures:
Exercise therapy — superior to doing nothing; specific rotator cuff and scapular stabilisation exercises are more effective than general shoulder exercises
Manual therapy — MT combined with exercise outperforms exercise alone, particularly at shorter follow-up periods
Taping - for short term relief and protection from reaggravation, light taping to support the shoulder can be beneficial in recovery
Activity modification — reducing overhead loading and avoiding movements that reproduce pain above 90° of abduction
Postural correction — addressing internal rotation and forward shoulder posture; pectoral stretching is a key adjunct
Ergonomic advice — particularly relevant in laptop users, drivers, and overhead workers
NSAIDs — though Osteopaths cannot give specific medication advice, NSAIDs referred from the appropriate practitioner is shown to be superior to placebo for short-term pain relief
Eccentric loading — slow, controlled lowering (eccentric) exercises have been shown to support tendon remodelling and endurance recovery in subacromial conditions, and are a valuable component of the home program.
Avoiding complete immobilisation - Slinging the shoulder without concurrent exercise tends to perpetuate guarding, promote further restriction, and delay recovery. Movement — in the right range and with appropriate load — is preferable.
Where To Start
If you suspect your pain may be related to an inflamed bursa, booking your osteopathic consultation sooner rather than later allows a quicker response to creating your tailored management plan. Since the most common type of bursitis is chronic, the recovery time can often be weeks to months, hence why it is essential to address your pain sooner rather than later.
Whilst understanding all of the above can benefit your management and recovery process, it’s important to understand that not one-size-fits-all. Seeking advice from your Osteopath ensures you have an appropriate plan of action to recovery tailored to your body’s needs.
