5 Common Causes of Shoulder Pain

Ever reached for an item on a high shelf and felt a sharp stab of pain shoot through your shoulder? Or awakened to discover you couldn’t raise your arm without grimacing? If so, you’ve joined the millions worldwide who battle shoulder pain. What turns basic daily tasks like dressing or reaching into a cupboard into torturous ordeals? At Physical Therapy Advantage, we believe understanding the common causes is the first step, and our approach to shoulder pain therapy can change your life.

Understanding Shoulder Anatomy: Why This Joint Is So Vulnerable

The shoulder is a ball-and-socket joint made up of the humerus, scapula, and clavicle, making it the body’s most mobile joint with a wide range of motion. However, this mobility reduces stability. The rotator cuff—a group of four muscles and tendons—acts as the main stabilizer. If one muscle is injured, the whole system suffers. Like a golf ball on a tee, the shoulder is flexible but naturally unstable, which is why shoulder pain therapy focuses on strengthening the surrounding musculature.

The 5 Most Common Causes of Shoulder Pain

1. Rotator Cuff Injuries: The Silent Epidemic

Rotator cuff injuries rank as the leading cause of shoulder pain, with over 2 million Americans affected annually. These injuries encompass a range from mild inflammation (tendinitis) to full tendon tears. What’s so widespread about rotator cuff issues? The answer lies in daily life. Consider how much we reach overhead, type at computers, lift boxes, and even sleep in positions that strain the shoulder.

How They Develop:

Rotator cuff injuries can emerge through two primary routes: sudden acute injury or slow chronic degeneration. The former could occur after a fall, lifting heavy weights, or jerking motions. But in reality, gradual degenerative tears are more common. Over time, with age and repetitive use, the tendons fray and weaken.

Functional Impact:

Deep, aching pain that worsens at night
Weakness when lifting or rotating the arm
Difficulty reaching behind the back or overhead
A "catching" sensation with certain movements

The toll on mental health can also be high. Basic self-care tasks like combing hair, dressing, or grabbing a plate become constant reminders of our limitations.

2. Frozen Shoulder (Adhesive Capsulitis): The Mysterious Condition

Frozen shoulder plagues about 2-5% of the population. Women over 40 are at particular risk. The condition occurs when the shoulder capsule becomes thick and tight, severely restricting range of motion. The name is apt: patients feel like the joint is literally frozen in place.

How It Develops:

Freezing Phase (2-9 months): Gradual onset of pain and stiffness
Frozen Phase (4-12 months): Pain may decrease, but stiffness remains severe
Thawing Phase (12-42 months): Gradual return of range of motion

Functional Impact:

The condition can quickly turn independent people into those who need help with basic activities. Actions like reaching into a back pocket, fastening a bra strap, or washing hair become nearly impossible. The psychological consequences can include frustration, sleep disruption, and low quality of life.

3. Shoulder Impingement Syndrome: The Overhead Athlete's Nemesis

Shoulder impingement occurs when the rotator cuff tendons get pinched against the acromion (shoulder blade bone) as the arm lifts. This injury is common in athletes doing overhead activities, hence the nickname “swimmer’s shoulder”.

How It Develops:

Many factors contribute to impingement syndrome, including:

Poor posture leading to altered shoulder mechanics
Muscle imbalances between the chest and back
Repetitive overhead activities
Anatomical variations in bone structure
Age-related changes in tendons

Functional Impact:

Impingement creates a painful arc of motion between 60-120 degrees. Activities like reaching for something on a shelf, throwing, or even brushing hair become accompanied by a sharp catching pain. Athletes may note decreased performance and movement apprehension.

4. Shoulder Arthritis: The Wear and Tear Reality

Shoulder arthritis afflicts over 16 million Americans, with osteoarthritis (OA) being most common. This condition results from cartilage covering the joint surfaces wearing away. The result is bone-on-bone contact and inflammation.

How It Develops:

Arthritis can develop in several ways:

Natural aging processes
Previous shoulder injuries
Genetic predisposition
Repetitive stress over time
Inflammatory conditions like rheumatoid arthritis

Functional Impact:

Arthritis pain tends to start mild but gets steadily worse. Unlike with other shoulder injuries, arthritic pain often occurs at rest and may worsen with cold or damp weather. Stiffness in the morning and after sitting for a while becomes a hallmark. Severe arthritis can dramatically limit function and cause visible joint deformity.

5. Shoulder Instability: When the Joint Won't Stay Put

Shoulder instability is when the humeral head (ball) slips out of the glenoid (socket) partially (subluxation) or fully (dislocation). Acute dislocations draw attention, but chronic instability: when the shoulder feels loose or unreliable: can be more problematic.

How It Develops:

Traumatic dislocations that damage stabilizing structures
Repetitive overhead activities that gradually stretch ligaments
Genetic factors leading to naturally loose joints
Previous surgical complications

Functional Impact:

Patients with shoulder instability often feel like their shoulder is about to “pop out” during activities. This generates anxiety and avoidance patterns. Athletes may fear certain movements and lose confidence in their abilities. Non-athletes will often change daily activities to avoid a potential dislocation.

Therapeutic Techniques: The Healing Arsenal

Manual Therapy: The Hands-On Approach

At Physical Therapy Advantage, our skilled therapists use their hands to mobilize joints, manipulate soft tissues, and restore movement patterns. Effective for conditions like frozen shoulder, benefits include:

Passive range of motion
Active-assisted range of motion
Active range of motion
Resistive range of motion

The Transformative Benefits of Physical Therapy for Shoulder Pain

Physical therapy for shoulder pain provides many benefits that drastically improve patients’ lives. Evidence shows a range of important outcomes.

Pain Relief: Breaking the Cycle

Physical therapy for shoulder pain delivers effective non-drug pain relief. Exercises help release endorphins, manual therapy activates pain-blocking pathways, and movement inhibits inflammatory pathways.

Research shows shoulder pain patients experience 40-70% pain reduction after 6-8 weeks of therapy. It also addresses the pain causes, which means patients get long-lasting relief and usually remain free of symptoms after completing treatment.

Improved Mobility: Reclaiming Freedom

A key issue with shoulder pain is the vicious cycle of stiffness. The less we move, the stiffer we get, which leads to more pain, and causes further movement avoidance. Shoulder pain therapy breaks this cycle through progressive mobility restoration. Patients are often amazed at how much their daily function can improve. Regaining mobility also has a positive psychological impact.

Faster Recovery: Optimizing Healing

Professional shoulder pain therapy can speed up recovery, as therapists optimize the healing process. Controlled movement and progressive loading promote blood flow to the area, stimulating tissue remodeling. Manipulation can also be helpful in certain situations. The earlier therapy is started, the better the outcomes and the more pain patients can avoid. As a result, those getting early intervention usually recover 30-50% faster.

Injury Prevention: Building Resilience

Therapy prevents injury by addressing muscle imbalances, improving movement, and building strength.

Prevention strategies include:

Strengthening exercises
Flexibility training
Movement education
Activity modification
