Shoulder Pain: Causes, Symptoms, Treatment & Prevention

What Is Shoulder Pain?

Shoulder pain is a common problem that can affect people of all ages. It may develop gradually due to repetitive movements and overuse, or suddenly following an injury.

The shoulder is a complex joint that allows a wide range of movement. Because it is involved in many everyday activities, shoulder pain can make simple tasks such as reaching, lifting, dressing or sleeping uncomfortable.

While some cases of shoulder pain may improve with rest and appropriate self-care, persistent symptoms may require professional assessment.

What Causes Shoulder Pain?

There are many possible causes of shoulder pain, ranging from muscle strain to injuries and joint conditions.

1. Muscle Strain and Overuse

Repeated movements involving the shoulder can place stress on the muscles and tendons.

This is common among people who frequently perform activities such as:

• Lifting.
• Reaching overhead.
• Repetitive work.
• Sports activities.
• Exercise involving the upper body.

Overuse may lead to muscle fatigue, stiffness and shoulder pain.

2. Rotator Cuff Problems

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

Rotator cuff problems may develop due to overuse, ageing or injury. Symptoms may include shoulder pain, weakness and difficulty raising the arm.

3. Frozen Shoulder

Frozen shoulder, also known as adhesive capsulitis, can cause significant stiffness and shoulder pain.

People with frozen shoulder may have difficulty performing everyday movements such as reaching behind their back, lifting their arm or putting on clothes.

4. Shoulder Impingement

Shoulder impingement can occur when structures around the shoulder become irritated during certain movements.

It may cause pain when raising the arm, particularly during overhead activities.

5. Shoulder Injuries

Falls, sports injuries and accidents can damage the muscles, tendons, ligaments or other structures around the shoulder.

A sudden injury may result in pain, swelling, weakness or restricted movement.

6. Arthritis

Changes within the shoulder joint caused by conditions such as osteoarthritis may contribute to shoulder pain, stiffness and reduced mobility.

Common Symptoms of Shoulder Pain

The symptoms of shoulder pain can vary depending on the underlying cause.

Common symptoms include:

• Pain in the shoulder.
• Shoulder stiffness.
• Difficulty raising the arm.
• Reduced range of motion.
• Muscle weakness.
• Pain when reaching overhead.
• Pain when lifting objects.
• Pain that becomes worse at night.
• Discomfort when sleeping on the affected shoulder.
• Pain that spreads towards the upper arm or neck.

If these symptoms persist or interfere with your daily activities, it is advisable to seek professional assessment.

Why Does Shoulder Pain Get Worse at Night?

Some people experience increased shoulder pain at night, especially when lying on the affected side.

Certain shoulder conditions may become more noticeable during rest because of the position of the arm and shoulder.

If shoulder pain regularly affects your sleep, consider getting assessed to determine the underlying cause.

Shoulder Pain From Working at a Desk

Although shoulder pain is often associated with physical activities, office workers can also experience discomfort.

Spending long hours at a computer may contribute to tension around the neck, shoulders and upper back, particularly when the workstation is not set up appropriately.

To improve your workstation:

• Keep your monitor at a comfortable height.
• Keep your shoulders relaxed.
• Avoid constantly reaching forward for your mouse or keyboard.
• Sit with adequate back support.
• Take regular movement breaks.

Tips to Prevent Shoulder Pain

1. Maintain Good Posture

Poor posture can contribute to tension around the neck and shoulders.

Try to keep your head, neck and shoulders in a comfortable position when sitting and standing.

Avoid consistently rounding your shoulders or holding your head forward.

2. Take Regular Movement Breaks

If you work at a desk, avoid remaining in the same position for several hours.

Stand up, walk around and gently move your shoulders throughout the day.

Regular movement can help reduce stiffness and muscle tension.

3. Strengthen Your Shoulder and Upper Back Muscles

Strong shoulder and upper back muscles can help support shoulder movement.

Depending on your condition, exercises may include:

• Shoulder blade exercises.
• Resistance band exercises.
• Rotator cuff strengthening.
• Upper back strengthening.
• Postural exercises.

If you already experience shoulder pain, a physiotherapist can help determine which exercises are appropriate for you.

4. Warm Up Before Exercise

Before participating in sports or upper-body workouts, spend some time warming up.

A proper warm-up prepares your muscles and joints for physical activity and allows you to gradually increase the intensity of your movements.

5. Use Proper Lifting Techniques

Incorrect lifting techniques can place unnecessary stress on the shoulder.

When lifting an object, keep it close to your body and avoid suddenly jerking or twisting your shoulder.

For heavier objects, ask for assistance when necessary.

Exercises for Shoulder Health

Regular exercise can help maintain shoulder mobility and strength.

Depending on your condition, a physiotherapist may recommend exercises such as:

Shoulder Rolls

Gentle shoulder rolls can help promote movement and reduce stiffness.

Shoulder Blade Squeezes

This exercise focuses on the muscles around the shoulder blades and upper back.

Resistance Band Exercises

Resistance bands can be used for gradual strengthening of the shoulder and rotator cuff muscles.

Range-of-Motion Exercises

Gentle movement exercises can help maintain shoulder flexibility and mobility.

Important: Exercises should be appropriate for your individual condition. If an exercise significantly increases your shoulder pain, stop and seek professional advice.

How Is Shoulder Pain Diagnosed?

A healthcare professional or physiotherapist may assess your shoulder by looking at:

• Your symptoms and medical history.
• Shoulder range of motion.
• Muscle strength.
• Joint movement.
• Posture.
• Movement patterns.
• Functional activities.

Depending on the symptoms and suspected condition, further investigations such as an X-ray, ultrasound or MRI may sometimes be recommended.

Can Physiotherapy Help With Shoulder Pain?

Physiotherapy can be an effective part of managing many types of shoulder pain.

A physiotherapist can assess your shoulder movement, strength, flexibility and functional limitations before developing an appropriate treatment programme.

Treatment may include:

• Therapeutic exercises.
• Shoulder strengthening.
• Mobility exercises.
• Stretching.
• Manual therapy.
• Postural correction.
• Movement retraining.
• Ergonomic advice.
• Activity modification.

The goal of physiotherapy is to help improve movement, reduce symptoms and support a gradual return to normal activities.

How to Maintain Healthy Shoulders

Taking care of your shoulders should be part of your everyday routine.

You can support shoulder health by:

• Staying physically active.
• Maintaining good posture.
• Strengthening your shoulders and upper back.
• Stretching regularly.
• Taking breaks from repetitive activities.
• Warming up before exercise.
• Using proper lifting techniques.
• Avoiding sudden increases in exercise intensity.
• Allowing enough time for recovery.

Small changes to your daily habits can help keep your shoulders strong and mobile.

Conclusion

Shoulder pain can be caused by many different factors, including overuse, muscle strain, rotator cuff problems, frozen shoulder, injuries and joint conditions.

While some mild symptoms may improve with appropriate self-care, persistent shoulder pain should not be ignored, especially when it affects your movement, sleep or daily activities.

Physiotherapy can help identify movement problems, improve shoulder strength and mobility, and support a safe return to everyday activities.

If you are experiencing ongoing shoulder pain, consider speaking with a doctor or physiotherapist to determine the possible cause and the most appropriate treatment for your condition.
