Rotator Cuff Tear vs. Shoulder Strain: When Is Shoulder Pain More Serious?

By: Dr. Thomas Fox, Orthopedic Surgeon

When shoulder pain begins, it's common to wonder whether you've simply strained something or injured your rotator cuff. However, the answer isn't always obvious. Shoulder pain can have many causes, and even rotator cuff problems can range from temporary irritation to a partial or complete tendon tear. Understanding how your symptoms began and how your shoulder is functioning can provide important clues about when it's time to have the problem evaluated.

Why Shoulder Pain Doesn't Always Mean a Rotator Cuff Tear

The shoulder is a complex joint that depends on muscles, tendons, ligaments, and other structures working together to provide a wide range of motion. The rotator cuff consists of four muscles and their tendons that help stabilize the shoulder and allow you to lift and rotate your arm. However, pain in this area doesn't automatically mean one of those tendons is torn.

Shoulder pain can also result from a muscle or tendon strain, bursitis, tendinitis, arthritis, instability, or other conditions. Repetitive activities such as painting, lifting, gardening, swimming, playing tennis, or other overhead movements can irritate the tissues around the shoulder without causing a significant tear.

A strain occurs when a muscle or tendon is overstretched or injured. Symptoms may include soreness, tenderness, swelling, weakness, or pain with certain movements. Many minor strains improve with activity modification and time. Rotator cuff tears, however, involve a partial or complete disruption of one or more rotator cuff tendons. They can occur suddenly following an injury or develop gradually as the tendon changes with age and repetitive use.

When Should Shoulder Pain Be More Concerning?

Pain alone can't tell us whether you have a rotator cuff tear. How the injury happened and whether you've experienced a change in strength or function can be particularly important. Symptoms that may warrant an orthopedic evaluation include:

• Persistent pain that worsens or doesn't improve with rest or activity modification
• Significant weakness when lifting or rotating your arm
• Difficulty raising your arm overhead
• Pain that regularly interferes with sleep
• Loss of normal range of motion
• Symptoms that begin after a fall, sudden pull, or other traumatic injury
• A noticeable loss of function following an injury

A sudden injury followed by significant weakness or an inability to lift your arm deserves particular attention. However, not every rotator cuff tear causes dramatic symptoms. Some tears develop gradually, and small tears may cause relatively little pain. That's another reason symptoms alone aren't enough to determine what's happening inside the shoulder.

How Is a Rotator Cuff Tear Diagnosed?

An orthopedic evaluation usually begins with a discussion of how your symptoms started, where you feel pain, which movements bother you, and whether you've noticed changes in strength or function. During a physical examination, we evaluate your shoulder's range of motion, strength, stability, and tenderness. Specific movements can also help us assess the rotator cuff and other structures that may be contributing to your symptoms.

Additionally, we may order imaging depending on our findings. An MRI or ultrasound provides a better view of soft tissues and can help determine whether a rotator cuff tendon is torn, which tendon is involved, and the size and extent of the tear. X-rays can help identify other potential causes of shoulder pain, including arthritis or bone changes. The appropriate diagnostic approach depends on your symptoms, examination, medical history, and how the problem occurred.

Does a Rotator Cuff Tear Always Require Surgery?

A rotator cuff tear doesn't automatically mean surgery. Treatment depends on several factors, including whether the tear developed gradually or resulted from an injury, its size and severity, your age and overall health, activity level, symptoms, and how much the shoulder problem affects your daily life.

For many patients, initial treatment may include activity modification, strengthening and flexibility exercises, anti-inflammatory or pain-relieving medications and, for certain patients, corticosteroid injections. Physical therapy can also be particularly important for restoring motion, strengthening the muscles surrounding the shoulder, and improving function. In other situations, surgical repair may be appropriate, particularly when a significant tear follows an acute injury, weakness or loss of function persists, or nonsurgical treatment hasn't improved symptoms enough.
