The shoulder is the most mobile joint in the human body, and that mobility comes at the cost of stability. It is a remarkable piece of engineering, and when it goes wrong, it can be genuinely disabling, robbing you of sleep, making it impossible to reach overhead or behind your back, and turning simple tasks like dressing into ordeals.
The trouble is that "shoulder pain" is not one diagnosis. Several distinct conditions produce overlapping symptoms, and they are treated quite differently. At Bromberg Chiropractic, the first job with any shoulder injury is an accurate diagnosis. This post walks through the most common causes and how we approach them.
A Quick Tour of the Shoulder
The shoulder is a ball-and-socket joint where the head of the upper arm bone sits in a shallow socket on the shoulder blade. Because the socket is shallow (think of a golf ball on a tee), the joint depends heavily on soft tissue for stability: the rotator cuff (four muscles and their tendons that cup the joint), the labrum (a cartilage rim), the joint capsule, and several bursae (fluid-filled cushions). Problems with any of these structures produce shoulder pain.
The Most Common Culprits
Rotator Cuff Tendinopathy and Tears
The rotator cuff tendons are the most common source of shoulder pain. They can become irritated and degenerated (tendinopathy) from overuse and age, or partially or fully torn from injury or chronic wear. The hallmark is pain with overhead activity and reaching, weakness when lifting or rotating the arm, and night pain, especially when lying on the affected side. Many rotator cuff problems respond well to conservative care; even some tears do not require surgery.
Shoulder Impingement
Impingement occurs when the rotator cuff tendons and a bursa get pinched in the narrow space beneath the bony arch of the shoulder blade, usually during overhead motion. It often coexists with rotator cuff irritation and frequently stems from poor mechanics, a forward-rounded posture, a tight joint capsule, and weak stabilizing muscles that let the arm bone ride too high in the socket.
Frozen Shoulder (Adhesive Capsulitis)
Frozen shoulder is its own distinct, often misunderstood condition. The joint capsule becomes inflamed, thickened, and progressively stuck, dramatically limiting motion in all directions, including when someone else tries to move your arm for you. That last point is a key distinguishing feature: with a rotator cuff problem you can often move the arm passively even when it hurts, but with a true frozen shoulder the motion is genuinely blocked.
Frozen shoulder classically moves through three phases: a painful "freezing" phase, a stiff "frozen" phase, and a gradual "thawing" phase. It is more common in people with diabetes and thyroid conditions, and after a period of shoulder immobilization. Left entirely alone it can take one to three years to resolve; appropriate treatment can meaningfully shorten that course and reduce the pain along the way.
AC Joint and Arthritis
Pain localized to the top of the shoulder often comes from the acromioclavicular (AC) joint, where the collarbone meets the shoulder blade, from old injuries or arthritis. Degenerative arthritis of the main shoulder joint is another cause, particularly in older patients.
How We Sort It Out
Accurate diagnosis is everything here, because the treatment for a frozen shoulder differs from the treatment for impingement or a cuff tear. Our evaluation includes a detailed history, specific orthopedic tests that stress individual structures, assessment of both active and passive range of motion, and a look at your posture and shoulder-blade mechanics. When the picture warrants it, we coordinate imaging to confirm the diagnosis.
How We Treat Shoulder Problems
For the large majority of shoulder conditions, conservative care is the appropriate first line, and often resolves the problem.
Soft Tissue Therapy
The rotator cuff and the surrounding muscles almost always harbor adhesions and trigger points. Active Release Technique and other soft tissue work restore healthy tissue glide, reduce pain, and improve motion, particularly valuable in frozen shoulder, where restoring capsule and tissue mobility is the central goal. Our post on how ART works goes deeper on the technique.
Joint Mobilization and Adjustment
Restricted motion in the shoulder joint itself, and just as importantly in the thoracic spine and shoulder blade, drives many shoulder problems. Restoring motion to these areas with adjustments and mobilization takes pressure off the cuff and improves overhead mechanics.
Rehabilitative Exercise
This is the backbone of lasting shoulder recovery. Targeted exercises restore the strength and coordination of the rotator cuff and the shoulder-blade stabilizers, retraining the arm bone to sit and move correctly in the socket. For frozen shoulder, a carefully graded stretching and motion program is essential.
When Surgery Is Considered
Most shoulder pain does not need surgery. The situations that warrant surgical consultation include large, full-thickness rotator cuff tears with significant weakness, tears that fail an adequate trial of conservative care, certain labral injuries, and advanced arthritis. Even in many of these cases, conservative care is worth trying first or is used to optimize the shoulder before and after any procedure.
Do Not Let It Freeze
One practical warning: shoulder pain that makes you stop using the arm can become a self-fulfilling prophecy. Immobility breeds stiffness, and stiffness is a setup for frozen shoulder. If you have shoulder pain that is limiting your motion or disturbing your sleep, get it evaluated rather than waiting it out.
