Shoulder Pain When Lifting Arm? It May Be Your Rotator Cuff

Do you feel shoulder pain when lifting your arm, reaching overhead, or carrying something heavy? This is one of the most common shoulder complaints seen by orthopaedic surgeons. Often, the underlying cause is a rotator cuff injury — particularly a rotator cuff tear.

Whether the pain appeared suddenly after exercise or gradually over time, understanding what’s happening inside your shoulder can help you seek the right treatment before the problem worsens.

What Is The Rotator Cuff?

The rotator cuff is a group of four muscles and their tendons that surround the shoulder joint. These muscles are:

1. Supraspinatus – helps lift the arm away from the body.
2. Infraspinatus – assists with external rotation.
3. Teres Minor – supports stability and rotation.
4. Subscapularis – controls internal rotation.

Together, they keep the shoulder ball (humeral head) stable within its socket while allowing smooth and controlled motion. Because of its complexity and range of movement, the shoulder joint is highly flexible — but also vulnerable to strain and injury.

Why Do Rotator Cuff Tears Happen?

Rotator cuff tears occur when one or more of these tendons become damaged or completely torn. This can happen suddenly during trauma, or develop slowly over time due to wear and tear.

1. Acute Injury

A sudden fall, lifting a heavy object, or a forceful overhead movement (like throwing or pulling) can tear the rotator cuff instantly. This is more common in sports such as tennis, badminton, or weightlifting.

2. Degenerative Wear And Tear

Over time, the tendons naturally weaken due to repetitive use or age-related degeneration. People over 40 are more prone to this type of tear, especially if their jobs or hobbies involve frequent overhead motions.

3. Poor Posture Or Shoulder Mechanics

Forward-rounded shoulders or muscle imbalances can increase friction and pressure on the tendons, eventually leading to inflammation (tendinitis) or a partial tear.

4. Reduced Blood Flow

With age, blood supply to the rotator cuff decreases, slowing healing and making the tissue more prone to injury.

What Are The Common Symptoms Of A Rotator Cuff Tear?

Pain in the shoulder when lifting the arm is one of the hallmark symptoms. However, several other signs can accompany it:

• Sharp or aching pain when raising or lowering the arm
• Pain that worsens at night, especially when lying on the affected shoulder
• Weakness when trying to lift or rotate the arm
• Crackling or clicking sounds (crepitus) during movement
• Limited range of motion, making it hard to comb hair, reach overhead, or fasten a seatbelt

In mild cases, you may only notice discomfort during specific activities. In more severe tears, even simple tasks such as dressing or reaching for a cupboard can become painful.

When To See An Orthopaedic Surgeon For Shoulder Pain?

You should seek medical attention if:

• The shoulder pain persists for more than a week, even with rest and ice.
• You experience sudden pain and weakness after an injury or heavy lift.
• The pain interferes with daily activities or sleep.
• There is visible swelling, bruising, or loss of strength.

A prompt evaluation by an orthopaedic surgeon is important. Early diagnosis can prevent further damage and improve recovery outcomes.

How A Rotator Cuff Tear Is Diagnosed

The orthopaedic surgeon will diagnose shoulder pain starting with a physical examination, testing your shoulder’s range of motion, strength, and stability.

Imaging tests such as ultrasound or MRI scans are often recommended to determine the extent of the tear and check for associated conditions like bursitis or impingement.

Treatment Options For Rotator Cuff Tears

Treatment depends on the severity of the tear, your age, activity level, and overall health. The main options include:

1. Non-Surgical Treatment

• Rest and Activity Modification: Avoid movements that worsen the pain, especially overhead lifting.
• Physiotherapy: Strengthening the surrounding muscles helps restore function and relieve discomfort.
• Anti-Inflammatory Medications: Reduce pain and swelling.
• Corticosteroid Injections: Offer temporary relief for inflammation and pain.

Many partial tears respond well to conservative treatment, especially when started early.

2. Surgical Treatment

For complete tears or cases that do not improve with non-surgical care, rotator cuff repair surgery may be recommended. This procedure reattaches the torn tendon to the bone, often using minimally invasive arthroscopic techniques.

After surgery, rehabilitation and physiotherapy are crucial to regain strength, flexibility, and shoulder stability.
