1. What Is Shoulder Pain?

As a medical technologist in physiotherapy, I see patients with shoulder pain almost every day. Some come in unable to lift their arm to comb their hair. Others can't sleep because the pain wakes them up at night. Some are scared they've torn something and will need surgery.

After years of working in the clinic, I've learned that most shoulder pain is treatable—but only if you understand what's causing it.

Shoulder pain refers to discomfort around the shoulder joint or the surrounding muscles, tendons, ligaments, and other tissues. The shoulder is a highly mobile joint that allows the arm to move in many directions.

Because of this mobility, the shoulder can be affected by injuries, inflammation, stiffness, and other conditions. Sometimes, pain felt in the shoulder comes from another part of the body, such as the neck or heart.

The appropriate treatment depends on the cause of the pain.

2. What I See in the Clinic

Before I explain the causes, let me tell you what I actually see. Most patients I meet fall into three groups:

1. People who did too much too fast—gardening, moving furniture, starting a new workout.

2. People whose shoulder has gradually stiffened over months—often frozen shoulder.

3. People who injured it suddenly—falls, sports, car accidents.

In my experience:

• The first group usually recovers fastest because they seek help early.
• The second group waits too long because the pain is slow and they think it will go away.
• The third group needs urgent assessment.

What I tell my patients: If you're in the second group, don't wait. The earlier you start treatment, the easier it is to fix.

3. Common Causes of Shoulder Pain

1. Rotator Cuff Injury

In my clinic, this is one of the most common shoulder issues I see, especially in people over 40. The rotator cuff is a group of muscles and tendons that stabilize your shoulder.

When they're irritated or torn, you'll often feel pain when reaching overhead or lifting. The tricky part? Many people ignore it until the tear gets worse.

I always tell my patients, "If lifting your arm hurts, don't push through it—get it checked."

2. Shoulder Impingement

Shoulder impingement is a term commonly used for shoulder pain associated with movement and irritation of the tissues around the shoulder. Pain may become more noticeable when reaching overhead.

3. Frozen Shoulder (Adhesive Capsulitis)

A frozen shoulder causes pain and progressive stiffness, making it difficult to move the shoulder. Both active and passive shoulder movements may become restricted.

Read more about frozen shoulder and physiotherapy.

4. Fracture

A fracture involving the collarbone, upper arm bone, or shoulder blade may cause severe pain, swelling, bruising, and difficulty moving the arm. It often occurs following a fall or other injury.

5. Shoulder Arthritis

Arthritis can affect the shoulder joint and cause pain, stiffness, and reduced movement. Symptoms may gradually worsen over time.

6. Shoulder Dislocation

A shoulder dislocation occurs when the upper arm bone moves out of its normal position in the shoulder socket. It usually causes significant pain and requires prompt medical treatment.

Do not attempt to put a dislocated shoulder back into place yourself.

7. Bursitis

Bursae are small fluid-filled sacs that help reduce friction around joints. Inflammation of a shoulder bursa can cause pain, particularly during arm movements.

8. Tendinitis

Tendinitis involves irritation or inflammation of a tendon. In the shoulder, it may cause pain during lifting, reaching, or other movements.

9. Referred Pain

Pain originating outside the shoulder — including from the neck or heart — can sometimes be felt in the shoulder.

Important: Shoulder pain accompanied by chest pressure, shortness of breath, sweating, nausea, or pain spreading to the jaw or arm may indicate a heart attack. Seek emergency medical care immediately if these symptoms occur.

4. Symptoms of Shoulder Pain

Symptoms vary according to the underlying cause. Common symptoms include:

• Pain when moving the shoulder or lifting the arm
• Pain at rest or during the night
• Shoulder stiffness and reduced range of motion
• Weakness when lifting or carrying objects
• Swelling or bruising following an injury
• Difficulty reaching overhead or behind the back
• Pain that spreads toward the neck or upper arm
• Numbness or tingling, which may indicate nerve involvement

Important: The sudden onset of severe pain, visible deformity, or an inability to move the arm after an injury requires urgent medical assessment.

5. Home Care for Shoulder Pain

Mild shoulder pain caused by overuse may improve with appropriate self-care. However, home treatment depends on the cause of the pain.

1. Apply a Cold Pack

For a recent injury or swelling, apply a cold pack wrapped in a towel for 15–20 minutes at a time. Never place ice directly on your skin.

Stop if the skin becomes excessively painful, numb, or irritated.

2. Avoid Activities That Increase Pain

Temporarily reduce heavy lifting, repetitive overhead movements, and other activities that aggravate your symptoms.

Avoid keeping the shoulder completely immobile for long periods unless a healthcare professional advises you to do so.

3. Maintain Gentle Movement

I know it's tempting to rest completely when your shoulder hurts. But in my experience, complete rest often makes things worse.

Unless you have a fracture or dislocation, gentle movement helps prevent stiffness.

Here's what I tell my patients: "If it hurts sharply, stop. If it's a dull ache, you can usually continue gently." Listen to your body, but don't let fear keep you frozen.

4. Use Medicines Carefully

Some people may benefit from pain-relieving medicines, but the appropriate option depends on their age, medical history, other medicines, and the cause of the pain.

Ask a pharmacist or healthcare professional for advice before using painkillers.

5. Seek Professional Advice

Consult a qualified healthcare professional if shoulder pain is severe, follows an injury, limits normal activities, or does not improve with appropriate self-care.

6. How Physiotherapy Helps With Shoulder Pain

This is my area, so I'll be specific. In my clinic, I don't give every patient the same exercises. Someone with a frozen shoulder needs different treatment than someone with a rotator cuff tear.

Here's what a typical physiotherapy program looks like for shoulder pain:

1. First, I assess how you move, what hurts, and what you can't do

2. Then I teach you activity modifications — what to avoid and what's safe

3. We start with gentle range-of-motion exercises, then add strengthening as you improve

4. Finally, we work on getting you back to your normal activities — whether that's lifting your grandchild or returning to sports

A physiotherapy program may include:

• Assessment: Evaluating pain, shoulder movement, muscle strength, and functional limitations
• Education: Explaining activity modification, posture, and strategies to manage symptoms
• Range-of-motion exercises: Helping restore comfortable movement
• Strengthening exercises: Improving shoulder and shoulder-blade muscle function
• Functional rehabilitation: Gradually returning to daily activities, work, or sports

Important: Not every shoulder condition requires the same exercises. Following a fracture, dislocation, surgery, or suspected tendon tear, rehabilitation should follow appropriate medical assessment and professional guidance.

What I tell my patients: The exercises we do in the clinic are only part of the story. What you do at home matters even more. Consistency beats intensity every time.

7. How to Take Care of Your Shoulder Joints

These general habits may help support shoulder health:

• Maintain comfortable posture during work and daily activities
• Warm up before exercise or strenuous physical activity
• Take regular breaks from repetitive tasks
• Increase exercise intensity and lifting loads gradually
• Strengthen the shoulder and upper-back muscles with suitable exercises
• Avoid sudden or excessive movements that cause pain
• Seek professional advice when pain or restricted movement persists

Staying physically active and using appropriate movement techniques can help maintain shoulder function.

8. When to Seek Medical Attention

Seek Emergency Medical Care If:

Shoulder pain occurs with symptoms of a possible heart attack—chest pressure, shortness of breath, cold sweating, or pain spreading to the jaw or arm.

Obtain an Urgent Medical Assessment If You Have:

• Severe pain following an injury
• A visibly deformed shoulder or suspected dislocation
• Sudden inability to move the arm after an injury
• A hot, red, swollen shoulder accompanied by fever or feeling very unwell
• New or worsening weakness, numbness, or other concerning neurological symptoms

Arrange a Healthcare Assessment If:

The pain persists, repeatedly returns, disrupts sleep, or interferes with daily activities.

9. Frequently Asked Questions

What is the most common cause of shoulder pain?
In my clinic, rotator cuff problems and shoulder impingement are the most common. Frozen shoulder is also very common, especially in people over 40.

Can shoulder pain go away on its own?
Mild shoulder pain from overuse often improves with rest and gentle movement. But persistent pain—especially if it limits your movement—needs assessment.

Should I rest my shoulder completely?
No. Complete rest often makes stiffness worse. Unless you have a fracture or dislocation, gentle movement helps.

How long does shoulder pain take to heal?
It depends on the cause. Mild overuse injuries may heal in 1–2 weeks. Frozen shoulder can take months to years without treatment.

Do I need surgery?
Most shoulder pain doesn't require surgery. In my experience, physiotherapy and conservative treatment work for the majority of cases.

Can I prevent shoulder pain?
You can reduce your risk by strengthening your shoulder and upper-back muscles, warming up before activity, and avoiding sudden increases in activity.

10. Final Thoughts

Shoulder pain can be frustrating, but in my experience, most people improve with the right approach.

The key is to get an accurate diagnosis and start appropriate treatment early — not wait months hoping it will pass. If you're dealing with shoulder pain, don't ignore it. Get it assessed.

And if you're already in physiotherapy, stick with your home exercises. I've seen patients recover fully from injuries they thought would never heal. You can too.
