Shoulder Bursitis Treatment in Perth

The subacromial bursa is a fluid-filled sac that sits between the rotator cuff tendons and the acromion bone, reducing friction during shoulder movement. Bursitis refers to inflammation of this bursa, producing pain -- typically on the outer side of the shoulder -- that is aggravated by lifting the arm, reaching overhead, or lying on the affected side. It is one of the most common causes of shoulder pain and almost always arises secondary to another problem: rotator cuff weakness, tight posterior shoulder capsule, altered scapular movement, or repetitive overhead loading. Treating the bursa in isolation without addressing the driver leads to recurrence.

Yes, though they frequently co-exist. The rotator cuff is the group of four muscles and their tendons that stabilise the shoulder. A tear refers to structural damage to these tendons. Bursitis refers specifically to inflammation of the bursa. Both can produce pain on shoulder elevation and at the outer arm, and their presentations can overlap significantly on clinical examination. Ultrasound is useful for differentiating between them. Many patients with rotator cuff tendinopathy also have reactive bursitis from the tendon irritation. The treatment differs somewhat -- rotator cuff rehabilitation is the primary focus for tendinopathy, while anti-inflammatory approaches (relative rest, ice, and sometimes injection) are more relevant for acute bursitis.

Not necessarily. Many cases of subacromial bursitis resolve with physiotherapy alone, particularly when the underlying cause is addressed. However, corticosteroid injection is a useful adjunct in cases of severe or persistent pain that is limiting participation in rehabilitation. The evidence suggests injections work best as a short-term pain reduction tool that creates a window for physiotherapy to be more effective -- not as a standalone treatment. If pain is severe enough to prevent you engaging with exercise, an injection followed by physiotherapy typically produces better outcomes than either alone.

Acute bursitis from a specific incident (such as a fall or sudden overhead activity) often settles within 4-6 weeks with appropriate management. Chronic or insidious-onset bursitis -- particularly in repetitive overhead workers or throwing athletes -- requires addressing the underlying biomechanical drivers and typically takes 8-12 weeks of structured physiotherapy. The key predictor of outcome is whether the rotator cuff and scapular strength deficits that are driving the condition are adequately rehabilitated. Without this, bursitis tends to recur when loading is resumed.
