Shoulder Impingement: What Is Really Causing Your Shoulder Pain?
Shoulder pain is one of the most common problems affecting athletes and active adults. You may notice pain when reaching overhead, lifting weights, throwing a ball, putting on a shirt, or even sleeping on your shoulder. One common diagnosis associated with these symptoms is shoulder impingement.
But what is really causing the pain?
Shoulder impingement is not always as simple as something being “pinched” inside the shoulder. Your shoulder is a complex joint that depends on mobility, strength, stability, and coordination. When one part of that system is not working properly, it can change how the shoulder moves and increase stress on the surrounding tissues.
What Is Shoulder Impingement?
The shoulder is designed to allow a large amount of movement. The head of the upper arm bone, called the humeral head, sits inside a shallow socket called the glenoid.
Several muscles and tendons, including the rotator cuff, help control the position of the shoulder as you move.
Shoulder impingement symptoms can develop when tissues around the shoulder become irritated during certain movements. This may include the rotator cuff tendons or the bursa, a small fluid-filled structure that helps reduce friction.
Common symptoms include:
- Pain when reaching overhead
- Pain when lifting or lowering your arm
- Pain when reaching behind your back
- Shoulder weakness
- Pain while sleeping on the affected side
- Pain during pressing, throwing, swimming, or lifting activities
What Really Causes Shoulder Impingement?
There is rarely one single cause of shoulder pain.
A sudden increase in training, repetitive overhead activity, weakness of the rotator cuff, limited shoulder mobility, or poor control of the shoulder blade can all contribute to symptoms.
Your shoulder blade, or scapula, plays an important role in shoulder movement. It must move and rotate properly as your arm moves overhead. If shoulder blade movement is limited or poorly controlled, other tissues may experience increased stress.
Your thoracic spine, ribs, and even your hips can also influence how your shoulder moves.
This is why simply treating the painful area may not address the entire problem.
Is Shoulder Impingement the Same as a Rotator Cuff Tear?
No.
Shoulder impingement symptoms can occur with rotator cuff tendinopathy, bursitis, partial tears, or other shoulder conditions. However, experiencing shoulder pain does not automatically mean you have a rotator cuff tear.
A thorough physical examination can help determine which structures may be contributing to your symptoms. When appropriate, diagnostic ultrasound imaging can provide additional information about the rotator cuff tendons, biceps tendon, and other superficial soft tissues.
Ultrasound can also allow a trained clinician to evaluate certain tissues dynamically while the shoulder moves.
Why Shoulder Health Matters
Your shoulders are involved in much more than sports. You use them to reach, lift, carry, push, pull, work, exercise, and perform everyday activities.
When shoulder pain changes the way you move, you may begin compensating with other parts of your body. Over time, this can affect your neck, upper back, and even your ability to perform normal daily activities.
Maintaining healthy shoulder mobility, strength, and stability can help you stay active and reduce limitations caused by pain or injury.
How Physical Therapy Can Help
At Wall 2 Wall Sports & Rehab, we take a comprehensive approach to shoulder pain. Rather than simply treating the location of your pain, we evaluate your shoulder mobility, strength, stability, movement patterns, and activity demands.
Treatment may include rotator cuff strengthening, shoulder blade exercises, mobility work, manual therapy, progressive loading, and sport-specific rehabilitation.
For appropriate patients, diagnostic musculoskeletal ultrasound can provide additional information about the tissues involved and help guide treatment.
As a mobile physical therapy practice serving Glendale, Peoria, Surprise, Scottsdale, and the greater Phoenix area, Wall 2 Wall Sports & Rehab brings personalized sports physical therapy directly to you.
