Shoulder pain is a common issue, affecting up to 26% of adults at any given time. This discomfort can disrupt daily activities, from reaching for a high shelf to simply getting dressed.

Let's explore the key distinctions between these two common shoulder conditions.
What is Shoulder Impingement?
Shoulder impingement occurs when the space between the top of your shoulder blade (acromion) and the rotator cuff tendons narrows. This narrowing causes the acromion to rub against, or 'impinge' on, the tendons and the bursa (a fluid-filled sac that cushions the joint). Over time, this friction can lead to inflammation and pain.
Shoulder Impingement Symptoms
The symptoms of shoulder impingement often develop gradually and can vary in intensity. Common signs include:
- Pain at the front or side of your shoulder, which may radiate down your arm.
- Discomfort that worsens when you lift your arm overhead or reach behind your back.
- A feeling of weakness in the shoulder.
- Pain at night, especially when lying on the affected side.
What are the Shoulder Impingement Causes?
Shoulder impingement is frequently an overuse injury. It's common in people who perform repetitive overhead motions, such as swimmers, painters, and baseball players. Other shoulder impingement causes and risk factors include:
- Bone spurs on the acromion that reduce space in the joint.
- Poor posture, which can alter the shoulder's mechanics.
- Swelling of the bursa or rotator cuff tendons due to injury.
- Age-related wear and tear.
What is a Rotator Cuff Tear?
The rotator cuff is a group of four muscles and their tendons that surround the shoulder joint, keeping the head of your upper arm bone firmly within the shoulder socket. A rotator cuff tear happens when one or more of these tendons are torn, either partially or completely.
Symptoms of a Rotator Cuff Tear
The symptoms of a rotator cuff tear can sometimes overlap with those of shoulder impingement, but there are distinct differences. Look for:
- A dull ache deep within the shoulder.
- Significant weakness, making it difficult to lift objects or raise your arm.
- A cracking or popping sensation when moving your shoulder in certain ways.
- Pain that is persistent, often present even at rest.
- For acute tears from an injury, you might experience sudden, intense pain and immediate weakness.
Causes of Rotator Cuff Tears
Rotator cuff tears can result from a single, traumatic injury or from gradual degeneration over time.
- Acute Tears: These often happen from a fall on an outstretched arm or when lifting something too heavy with a jerking motion.
- Degenerative Tears: These are more common and occur as tendons wear down with age. Repetitive stress, bone spurs, and reduced blood supply to the tendons can contribute to their weakening and eventual tearing.
Diagnosing Shoulder Pain in Pittsburgh
Determining the exact cause of your shoulder pain requires a thorough evaluation from a specialist. The process of diagnosing shoulder pain typically involves several steps.
Physical Examination
Your doctor will discuss your symptoms and medical history before performing a physical exam. They will check your shoulder's range of motion, strength, and stability. Specific maneuvers, often called a shoulder impingement test, can help identify which movements cause pain and point toward the source of the problem. For example, the Neer test and Hawkins-Kennedy test are common methods used to check for impingement.
Imaging Tests
If a physical exam isn't conclusive, your doctor may order imaging tests to get a clearer picture of the inside of your shoulder.
- X-rays: While X-rays don't show soft tissues like tendons, they can reveal bone spurs or arthritis that might be causing impingement.
- MRI (Magnetic Resonance Imaging): This is the gold standard for visualizing soft tissues. An MRI can clearly show the rotator cuff tendons, bursa, and muscles, allowing your doctor to identify tears, inflammation, and other abnormalities.
- Ultrasound: This imaging technique uses sound waves to create real-time images of your muscles and tendons, and it can be effective in detecting rotator cuff tears.
Rotator Cuff Tear vs. Shoulder Impingement: Treatment Options
Once a diagnosis is confirmed, your treatment plan will be tailored to your specific condition, its severity, and your activity level.
Treatments for Shoulder Impingement
The goal of shoulder impingement treatment is to reduce inflammation and create more space in the shoulder joint.
- Rest and Activity Modification: Avoiding overhead activities can give the inflamed tendons time to heal.
- Physical Therapy: A physical therapist can guide you through exercises to strengthen the rotator cuff muscles, improve posture, and restore normal shoulder mechanics.
- Medication: Over-the-counter anti-inflammatory drugs (NSAIDs) like ibuprofen can help manage pain and swelling.
- Injections: Corticosteroid injections can provide powerful, short-term relief from inflammation.
- Surgery: If conservative treatments fail, a surgeon may perform a procedure called an acromioplasty to shave away part of the acromion, creating more space for the rotator cuff.
Treatments for Rotator Cuff Tears
Treatment for a rotator cuff tear depends on the size of the tear, your age, and your functional goals.
- Nonsurgical Options: For partial tears or in less active individuals, physical therapy, NSAIDs, and corticosteroid injections can be effective in managing symptoms and improving function.
- Surgical Repair: For complete tears or when conservative methods are unsuccessful, surgery may be necessary to reattach the torn tendon to the bone. This can often be done arthroscopically, using small incisions and a camera, which leads to less pain and a faster recovery.

Frequently Asked Questions
1. What are the common symptoms of shoulder impingement?
Shoulder impingement often causes pain when lifting the arm, reaching overhead, or performing certain activities. You may also experience weakness, stiffness, or a reduced range of motion in the affected shoulder.
2. How is a rotator cuff tear diagnosed?
A rotator cuff tear is typically diagnosed through a combination of a physical examination, medical history, and imaging tests such as an MRI or ultrasound. These methods help determine the severity and exact location of the tear.
3. Can shoulder pain go away on its own?
While mild shoulder pain may subside with rest and home care, persistent or severe pain often requires professional evaluation. Without treatment, symptoms of conditions like impingement or rotator cuff tears may worsen over time.
4. What are the treatment options for shoulder impingement?
Treatment can include physical therapy, anti-inflammatory medications, cortisone injections, or, in more severe cases, minimally invasive surgery to relieve the impingement and restore shoulder function.
5. When should I see a specialist for shoulder pain?
You should consult a specialist if you experience persistent pain, significant weakness, difficulty performing daily activities, or if the pain worsens despite resting and taking over-the-counter remedies. Early intervention can improve outcomes and prevent further complications.
