In late 2023, I felt an unexpected twitch in my right shoulder while exercising. The discomfort was mild at first, so I ignored it, but it gradually worsened into a persistent ache.

Raising my right arm – like when I was washing my hair – hurt. Certain movements, such as a tennis swing or when a lanyard I was holding got caught in a doorknob, sent sharp jolts of pain through my shoulder.

At night, I had to position my shoulder carefully as sleeping on the affected side was painful. I later developed neck pain on my right side, adding to my frustration.

A pain specialist diagnosed a likely strain of my rotator cuff – the set of shoulder muscles and tendons that help you lift, twist and rotate your arm while keeping the joint stable – as well as a strain of my trapezius muscles, which run along either side of the upper back.

She referred me to a physiotherapist at Singapore General Hospital (SGH). I began therapy in September 2024, not realising how long recovery would take.

After 14 long months of daily exercises and regular physiotherapy, I realised, one day, that I wasn’t moaning about my shoulder as much as I used to.

The pain no longer felt constant. Where I once could reach only the back of my head while shampooing, I could now wash my crown with no problem. At night, I didn’t have to treat my shoulder so gingerly.

I am not completely pain-free. When I overuse my right arm or keep my neck static for long periods – like when I’m working at the computer without a break – the pain will flare up, which is why I continue with the exercises and physiotherapy.

This experience also inspired The Physio Fix, a series in which I work with physiotherapists from SGH to show how physiotherapy can help address the aches and pains that many of us accept as part of getting older.

The shoulder joint has been called a marvel of human anatomy, allowing an incredible range of motion that lets us lift, reach, throw, carry, twist and turn with remarkable flexibility.

Dr Xia Zhan, a consultant in the department of orthopaedic surgery at SGH, says the shoulder joint is the most mobile joint in the human body.

Its wide range of motion comes from a ball-and-socket design, in which a large humeral head fits into a shallow glenoid socket. But the design comes with a trade-off. “This makes it also the least stable joint and highly susceptible to injury,” he says.

Shoulder pain can come from inside the joint. This happens when you fall or have an accident, resulting in fractures, dislocations and injuries to tendons or muscles. Pain can also be caused by conditions such as frozen shoulder, where the shoulder capsule stiffens and becomes inflamed; rotator cuff tendinitis, which is inflammation of the shoulder’s stabilising tendons; and arthritis, which involves joint inflammation and degeneration.

Dr Xia says pain can also originate outside the joint, such as when the cervical nerve roots in the neck are irritated. Conditions affecting the diaphragm or even the heart can also lead to shoulder pain, which is why it is essential to get an accurate diagnosis.

To determine the cause of shoulder pain, doctors ask about its history and symptoms, perform a physical examination and may order imaging such as X-rays, ultrasound scans or MRI scans. Warning signs such as severe pain, significant night pain, shoulder deformity, unexplained fever or shoulder pain accompanied by chest pain or breathlessness require urgent attention.

Dr Xia says treatment usually starts with pain relief, modification of activities that aggravate the pain, rest and physiotherapy. Injections such as steroids or platelet-rich plasma may be considered if needed, and surgery is generally a last resort after conservative care.

The Physio Fix

For many patients with shoulder discomfort, physiotherapy offers a real turnaround.

Ms Teo Yee Jean, a principal physiotherapist at SGH, says patients often complain of pain when lifting their arms sideways or overhead, for example when reaching for a top shelf or slipping into a shirt.

Pain usually stems from weakness, poor coordination or overuse of the shoulder and shoulder blade muscles. When these muscles have to work harder to achieve a movement, pain can follow.

Shoulder pain doesn’t discriminate by age. In younger people, it often stems from overtraining while exercising, doing too much too soon or using poor technique.

Older adults are susceptible due to decades of repetitive movements and heavy loads. Reduced muscle strength from ageing plays a role, and age-related changes in tendon structure can further increase vulnerability.

“The good news is that these changes are very responsive to the right exercises and rehabilitation,” Ms Teo says.

Physiotherapy works in two key ways, she adds.

First, it helps patients understand that pain doesn’t always signal harm. Rather, the nervous system can become more sensitive after injury or prolonged strain. “Understanding this helps people worry less about causing damage and to feel safer when returning to normal movement,” she says. Second, it gives patients a structured exercise programme to rebuild strength, improve control and regain confidence in using their shoulder.

Exercises usually combine stretching and strengthening.

“Stretching helps maintain flexibility and comfort, while strengthening improves support and stability,” Ms Teo says. Both are essential for everyday tasks such as lifting, reaching and carrying.

People with shoulder pain are generally encouraged to keep moving within comfortable limits. “In most cases, gentle movement is better than complete rest,” she says. “Some mild discomfort during movement is usually safe and normal. The goal is to stay active within tolerable limits while managing pain properly.”

Results don’t happen overnight, but most people notice improvement within six to 12 weeks of regular exercise and sticking to their programme. The road to full recovery varies depending on the condition being treated, the severity of the injury and how active the person is to begin with. Patience and consistency are essential.

Ms Teo’s advice on preventing shoulder pain is to stay physically active and keep the shoulder muscles strong. The exercises shown here can help. Maintaining good posture, taking regular breaks from repetitive work and lifting heavy loads below chest level – as opposed to above the shoulders – can also reduce strain on the shoulders.

She adds that most shoulder conditions can improve with the right treatment, but what holds some patients back is fear.

“What often matters more than the diagnosis itself is how worried or fearful a person feels about moving their shoulder,” she says. If someone is very worried or afraid of causing more pain, they may avoid using it, which can actually make the pain last longer.

On the other hand, she says, “confidence and gradual movement usually lead to better recovery”.

Shoulder internal rotation

Instructions

1. Securely tie a resistance band at waist height to something sturdy, such as a metal gate. Stand tall, shoulders relaxed and feet hip-width apart. Hold the band with your right hand in a comfortable grip. Keep your elbow bent at a 90-degree angle and close to your side.

2. Slowly pull your hand across your stomach in a controlled movement, keeping your elbow close to your side throughout.

3. Slowly return to the starting position. Repeat. To work the other shoulder, turn around, grab the band and repeat the movement with your left arm.

This exercise strengthens the shoulder stabilisers, helping to improve control and range of motion in the shoulder. It supports everyday movements such as lifting, pushing and reaching across the body, for example when closing a window or swinging a bag over your shoulder.

To do

10 repetitions per set / 2 sets on each arm / 2 times a week

Safety tips

Keep your elbow close to your body. Don’t let it flare out.
Maintain a 90-degree elbow bend. Straightening your arm can strain the shoulder.
Use a band that is taut but not difficult to pull.
Keep all movements slow and controlled.
Stop immediately if you feel sharp pain in the shoulder.


Shoulder external rotation

Instructions

1. Stand tall with your shoulders relaxed and feet hip-width apart. Hold a resistance band with both hands. The band should be taut, not tight. Bend your elbows to a 90-degree angle and keep them close to your sides.

2. Keeping your elbows by your sides, slowly pull your hands outwards, opening your chest.

3. Slowly return to the starting position in a controlled movement.

This exercise strengthens the rotator cuff muscles, which help stabilise and protect the shoulder joint. It is especially important for overhead movements, such as when you grab on to the bar of a train or wash your hair. It also helps improve posture and reduce the risk of shoulder strain or injury.

To do

10 repetitions per set / 2 sets / 2 times a week

Safety tips

Use light resistance. Choose a band that allows smooth, controlled movement without strain.
Keep your elbows close to your body to protect the shoulder joint and ensure the correct muscles are working.
Keep movements slow and controlled.
Stop immediately if you feel sharp pain or discomfort in your shoulder.


Wall angels

Instructions

1. Stand with your back against a wall, feet about 12cm away. Press your lower back, upper back and head gently against the wall. Bring your arms up so that your elbows are bent at a 90-degree angle. Try to keep the back of your hands against the wall if possible.

2. Slowly slide your arms up towards the ceiling, like making a snow angel, but against the wall. Slide only as far as you can. Pause for 1-2 seconds.

3. Slowly slide your arms down to the starting position and repeat.

This exercise strengthens the upper back and shoulder stabilisers. It improves posture and mobility in the shoulders and spine and helps counteract the effects of rounded shoulders caused by activities such as working at a computer.

To do

10 repetitions per set / 2 sets / Daily

Safety tips

Start with elbows at 90 degrees. This engages your shoulders and upper back safely and helps prevent arching or shrugging.
Keep your lower back gently against the wall. Avoid arching.
Move slowly and with control. Smooth movements help protect the joints and muscles.
Lift only as high as comfortable. Stop immediately if you feel pain in your shoulders or neck.


Wall push-ups

Instructions

1. Stand facing a wall, about an arm’s length away and feet hip-width apart. Place your palms flat on the wall at shoulder height and shoulder-width apart. If this feels difficult, lower your arms slightly below shoulder height. Keep your spine neutral and engage your core lightly.

2. Keeping your back straight and eyes forward, bend your elbows and slowly bring your chest and face towards the wall.

3. Pause briefly, then slowly push back to the starting position. Repeat, focusing on controlled, smooth movement.

This exercise strengthens the shoulder muscles and stabilisers, improving shoulder stability, control and posture. It supports everyday movements such as pushing open a door or pushing yourself up from a chair.

To do

10 repetitions per set / 2 sets / 2 times a week

Safety tips

Keep your spine neutral; avoid sagging or arching your back.
Move slowly and with control.
Keep your elbows at a comfortable angle; don’t flare them too far out.
Stop if you feel pain in your shoulders, wrists or neck.
