The shoulder is one of the most mobile joints in the body, allowing you to reach, lift and rotate your arm in many directions. Because of this flexibility, it is also more prone to injuries and wear-and-tear changes. Discomfort in the shoulder may present as a dull ache, stiffness, weakness or even sharp pain that limits movement. For some, it may come on suddenly after an injury, while for others, it develops gradually over time.

What causes Shoulder Pain?

Pain often arises when the structures that support the joint are stressed, irritated or damaged. Some of the key factors that may lead to shoulder pain include:

• Degeneration with age – as we grow older, the tissues in the shoulder naturally wear down, becoming less resilient and more prone to injury.

• Inflammation – irritation of the joint lining, tendons or surrounding soft tissue can cause swelling and tenderness.

• Instability – when the shoulder joint moves beyond its normal range, it may slip or partially dislocate, leading to discomfort and weakness.

• Nerve involvement – irritation or compression of nerves in the neck or upper spine can radiate pain into the shoulder area.

• Overuse and repetitive motion – frequent overhead activities, lifting or throwing can place excessive strain on the muscles and tendons, eventually leading to irritation and pain.

• Postural strain – poor posture, especially from prolonged sitting or slouching, can overload the muscles around the shoulder and neck, causing aches and stiffness.

• Trauma or sudden impact – falls, collisions or accidents can injure the shoulder directly, resulting in acute pain.

What other symptoms are associated with Shoulder Pain?

The way shoulder pain presents often provides clues to its underlying cause. Some people experience mild stiffness, while others may struggle with severe pain that limits daily activities.

Some of the possible symptoms include:

• Clicking or grinding sensations – mechanical sounds during movement, sometimes linked to structural issues.

• Night pain – discomfort that worsens when lying on the affected side or that interrupts sleep.

• Pain and tenderness – discomfort that may be sharp during movement or dull and aching at rest.

• Reduced range of motion – limitation in how far the shoulder can move in different directions.

• Swelling or warmth – signs of inflammation around the joint.

• Stiffness – difficulty raising the arm, reaching overhead or behind the back.

• Weakness – a sense that the arm feels heavy or lacks strength, particularly during lifting.

Can Shoulder Pain affect other parts of the body?

Although the source of discomfort may be in the shoulder itself, the pain can radiate to nearby areas such as the upper arm, neck or back. Occasionally, pain felt in the shoulder may not be caused by the joint at all but instead refers to other organs, such as the heart or lungs. This is why persistent or unexplained pain should always be carefully assessed by a doctor.

What could Shoulder Pain mean?

Several medical conditions can lead to shoulder discomfort, including:

• Arthritis – degeneration of the joint surfaces leading to pain and stiffness

• Bursitis – inflammation of the fluid-filled sac that cushions the joint

• Dislocations and fractures – usually the result of trauma or accidents

• Frozen shoulder – thickening and tightening of the joint capsule, causing severe stiffness

• Rotator cuff injuries – tears or inflammation of the tendons surrounding the joint

• Shoulder impingement – where tendons are pinched during arm movements

How is Shoulder Pain assessed in Singapore?

A proper evaluation is essential to understand the source of discomfort and guide the right treatment plan. The assessment generally entails:

• Medical history – Dr James Tan will ask detailed questions about the nature of the pain, when it started, any injuries or activities that may have triggered it. He will also ask how it affects daily life. This information helps narrow down the possible causes.

• Physical examination – the shoulder and surrounding areas are examined for swelling, tenderness, range of motion and strength. Specific tests may be carried out to check for instability, stiffness or nerve involvement.

• Imaging tests – X-rays, ultrasound scans or magnetic resonance imaging (MRI) scans may be recommended to provide a clearer view of the bones, joints, muscles and tendons. These tests help identify structural changes that may not be visible during a physical exam.

• Other investigations – blood tests may be carried out to rule out systemic conditions such as infection or inflammatory disease that could be contributing to the pain.

How is Shoulder Pain treated in Singapore?

Managing shoulder pain often involves a combination of approaches. The choice of treatment depends on the underlying cause, severity of the condition, and your lifestyle needs. This may include:

Conservative Treatments

• Rest and activity modification – avoiding repetitive or aggravating movements gives the shoulder a chance to heal while preventing further strain.

• Medication – non-steroidal anti-inflammatory drugs (NSAIDs) help to reduce pain and swelling, especially when used alongside other treatments.

• Heat and cold therapy – ice packs reduce inflammation in the early stages of pain, while heat can relax stiff muscles and promote circulation during recovery.

• Supportive aids – temporary use of taping or bracing may stabilise the joint and limit strain during movement.

Non-Surgical Interventions

• Physiotherapy – a structured programme of stretches and strengthening exercises designed to restore range of motion, stability, and function.

• Injections – corticosteroid injections can quickly reduce inflammation and pain, while platelet-rich plasma (PRP) injections use growth factors from the patient’s own blood to support healing.

Surgical Treatments

• Arthroscopic surgery – a minimally invasive procedure using small incisions and a camera to repair tendon tears, remove inflamed tissue or smooth bony surfaces.

• Open repair surgery – used for more complex cases where direct access to the joint is necessary.

• Subacromial decompression or bursectomy – relieves impingement by removing bone spurs or inflamed bursae.

• Shoulder replacement – in severe arthritis or major joint damage, traditional or reverse shoulder arthroplasty may be recommended.

• Stabilisation procedures – such as Bankart or SLAP repair, which address recurrent dislocations or ligament injuries.

• Biceps tendon surgery – treating pain or instability caused by damage to the biceps tendon.

Rehabilitation

• Targeted exercise programmes – gradual strengthening and flexibility exercises help restore shoulder function and reduce recurrence of injury.

• Post-operative physiotherapy – essential after surgery to regain mobility, build strength, and ensure proper healing.

• Lifestyle advice – guidance on posture, ergonomics, and safe return to sports or work activities forms a key part of long-term recovery.

Alternative Therapies

• Massage therapy – can reduce stiffness and promote relaxation, though it should be guided by a trained professional.

• Supplements and natural remedies – some people explore options such as glucosamine or turmeric for joint health, although evidence may vary.
