Introduction

Shoulder pain is one of the most common musculoskeletal complaints affecting adults of all ages. It may develop gradually through overuse or degeneration, or occur suddenly following a sporting injury or fall.

Although many episodes of shoulder pain improve with appropriate rest and rehabilitation, persistent pain, weakness or loss of movement may indicate an underlying shoulder condition that requires specialist assessment.

At 360 Orthopaedics, we provide evidence-based assessment and treatment for shoulder disorders, with an emphasis on accurate diagnosis and individualised care.

Common symptoms

Patients describe shoulder pain in many different ways.

Common symptoms include:

  • Pain when lifting the arm
  • Night pain that disrupts sleep
  • Difficulty reaching overhead
  • Pain while dressing
  • Weakness when lifting objects
  • Clicking or catching sensations
  • Shoulder stiffness
  • Pain after a sporting injury
  • Pain following a fall

What causes shoulder pain?

Shoulder pain is a symptom rather than a diagnosis.

Several different conditions may produce similar symptoms.

Rotator cuff disorders

The rotator cuff is a group of tendons that stabilise and move the shoulder.

Problems include:

  • Tendinitis
  • Partial tears
  • Full-thickness tears

Typical symptoms include pain when lifting the arm, weakness and night pain.

Frozen shoulder

Frozen shoulder causes progressive pain followed by increasing stiffness.

Patients often struggle with:

  • Reaching overhead
  • Fastening a bra
  • Putting on a jacket
  • Washing hair

Recovery may take many months without appropriate treatment.

Shoulder instability

The shoulder may partially or completely dislocate following injury.

Symptoms include:

  • Shoulder “giving way”
  • Apprehension during overhead activities
  • Recurrent dislocations
  • Clicking after previous injury

Young athletes are particularly at risk.

Shoulder arthritis

Wear of the shoulder joint cartilage can result in:

  • Pain
  • Stiffness
  • Reduced movement
  • Difficulty sleeping

Calcific tendinitis

Calcium deposits within the rotator cuff can produce sudden severe pain.

This condition often develops without obvious injury.

AC joint injuries

Falls onto the shoulder may injure the acromioclavicular joint.

Pain is typically located over the top of the shoulder.

When should I see a shoulder specialist?

You should consider specialist assessment if you experience:

✓ Pain lasting longer than 2–4 weeks

✓ Night pain affecting sleep

✓ Weakness

✓ Loss of shoulder movement

✓ Shoulder pain following a fall

✓ Recurrent dislocations

✓ Persistent pain despite physiotherapy

✓ Difficulty participating in work or sport


How is shoulder pain diagnosed?

Accurate diagnosis begins with a detailed clinical assessment.

This usually includes:

Medical history

Understanding:

  • how symptoms began
  • location of pain
  • activities that worsen symptoms
  • previous injuries
  • sporting activities

Physical examination

Assessment of:

  • shoulder movement
  • strength
  • instability
  • impingement signs
  • specific tendon function

Imaging

Depending on your symptoms, imaging may include:

X-rays

Useful for:

  • arthritis
  • fractures
  • calcific tendinitis

Ultrasound

Useful for:

  • rotator cuff tears
  • bursitis
  • tendon inflammation

MRI

MRI provides detailed assessment of:

  • tendons
  • cartilage
  • labrum
  • ligaments

MRI is not required for every patient.

Persistent shoulder pain, significant weakness, stiffness or symptoms following an injury may warrant assessment by a shoulder specialist.


Treatment

Treatment depends on the underlying diagnosis.

Many shoulder conditions improve without surgery.

Management may include:

  • Education
  • Activity modification
  • Physiotherapy
  • Pain management
  • Ultrasound-guided injections
  • Surgery when appropriate

Treatment is individualised according to:

  • diagnosis
  • age
  • activity level
  • occupation
  • sporting goals

Do all patients need surgery?

No.

Many shoulder conditions respond well to non-operative treatment.

Surgery is considered when:

  • structural damage is significant
  • symptoms persist despite appropriate treatment
  • instability recurs
  • function remains limited

The decision is made through shared discussion after reviewing your diagnosis, treatment options and personal goals.


Frequently Asked Questions

Is shoulder pain always caused by a rotator cuff tear?

No.

Several different conditions may produce similar symptoms.


Should I have an MRI before seeing a specialist?

Not necessarily.

The need for MRI depends on the clinical assessment. An examination and a review of any existing imaging done can help determine whether an MRI is likely to add useful information.


Can shoulder pain improve without surgery?

Yes.

Many patients recover with education, rehabilitation and appropriate non-operative treatment.


Should I continue exercising?

This depends on the diagnosis.

Maintaining general fitness is often encouraged, but certain activities may need to be modified temporarily until the cause of the pain has been identified.
