Injection Therapy for Subacromial Pain and Bursitis

What Is Subacromial Pain?

Subacromial pain describes pain arising from the tissues around the rotator cuff and subacromial bursa. It is sometimes referred to as shoulder impingement, rotator-cuff-related shoulder pain or subacromial bursitis.

Symptoms commonly include pain when lifting or lowering the arm, reaching overhead, dressing, lying on the affected side or completing repetitive tasks. Pain may also extend into the upper arm and can significantly disturb sleep.

The term covers several possible presentations. Accurate assessment is therefore important because pain around the shoulder can also arise from osteoarthritis, frozen shoulder, a significant rotator cuff tear, the acromioclavicular joint or the neck.

When Might a Corticosteroid Injection Be Appropriate?

A subacromial corticosteroid injection may be considered when the shoulder is highly irritable and pain is significantly affecting sleep, everyday function or the ability to begin rehabilitation.

It may also be relevant when symptoms have persisted despite appropriate activity modification, pain relief and exercise, or when pain needs to be reduced sufficiently to allow movement and strengthening to progress.

The decision should be based on the overall clinical presentation rather than the presence of “bursitis” on an ultrasound scan alone.

What Does a Subacromial Injection Do?

Corticosteroid is an anti-inflammatory medicine. When placed into the subacromial bursa, it may reduce pain and irritation around the rotator cuff and create a period in which movement, sleep and rehabilitation become more manageable.

Its benefit is usually greatest in the short term and varies between patients. The injection does not repair a damaged tendon, reverse structural changes or remove the underlying reasons that the shoulder became painful.

Do I Need an Ultrasound or MRI First?

Not routinely. Many presentations of subacromial pain can be identified through a detailed history and specialist clinical assessment.

Imaging may be helpful when symptoms followed significant trauma, there is marked weakness, the diagnosis remains uncertain, progress has been unexpectedly limited or the result would change treatment. Scan findings must always be interpreted alongside symptoms and examination findings because tendon and bursal changes are also common in people without shoulder pain.

Injection Therapy and Rehabilitation

A corticosteroid injection is most useful when it creates an opportunity to move and rehabilitate the shoulder more effectively. It should not normally be viewed as a complete treatment in isolation.

Once symptoms allow, rehabilitation may address shoulder movement, rotator-cuff strength, shoulder-blade control and tolerance of the activities that matter to you. The programme should be progressed according to your individual presentation rather than following a standard exercise sheet.

Research suggests that subacromial corticosteroid injection may provide modest short-term improvement, but superior long-term outcomes integrate rehabilitation and appropriate management of shoulder loading.

Specialist Shoulder Injections in Fareham

Assessment and injection therapy for subacromial pain are provided at our Fareham clinic by Mike Gillingham, Upper Limb Specialist Physiotherapist.

Mike will assess whether the symptoms are genuinely consistent with a subacromial presentation, whether corticosteroid is appropriate and how treatment should be integrated with rehabilitation or further investigation.
