Why Does My Shoulder Hurt When I Lift My Arm?
One of the most common complaints we hear is:
“My shoulder only hurts when I reach overhead.”
Whether you’re putting dishes away, washing your hair, reaching into a cabinet, or putting on a shirt, lifting your arm may produce a sharp pain that seems to catch unexpectedly.
One possible explanation is shoulder impingement.
Although the name sounds intimidating, shoulder impingement is often a treatable condition that responds well to appropriate conservative care when the underlying cause is identified.
What Is Shoulder Impingement?
Shoulder impingement occurs when the tendons of the rotator cuff—or the bursa that cushions them—become irritated as they pass beneath a portion of the shoulder blade called the acromion.
Normally, these tissues glide smoothly during shoulder movement.
However, when the available space becomes reduced or the shoulder moves inefficiently, the tendons and bursa may repeatedly become compressed or irritated.
Over time, this repeated irritation may contribute to:
- Pain
- Inflammation
- Weakness
- Reduced range of motion
- Difficulty performing overhead activities
The condition often develops gradually rather than appearing suddenly.
What Causes Shoulder Impingement?
Shoulder impingement is usually not caused by one single event.
Instead, it often develops from a combination of factors affecting how the shoulder moves.
Common contributing factors include:
- Repetitive overhead work
- Sports involving throwing
- Rotator cuff weakness
- Poor shoulder blade mechanics
- Muscle imbalance
- Poor posture
- Forward Head Posture
- Upper back stiffness
- Previous shoulder injuries
- Age-related tissue changes
In many patients, several of these factors work together.
That is why treatment should focus on restoring normal shoulder mechanics rather than simply reducing pain.
Common Symptoms
Patients with shoulder impingement frequently report:
- Pain when reaching overhead
- Pain lowering the arm
- Pain reaching behind the back
- Shoulder weakness
- Night pain
- Pain during exercise
- Difficulty lifting objects
- Pain near the front or outside of the shoulder
Many people also notice that symptoms worsen after repetitive activity but improve somewhat with rest.
As irritation progresses, everyday activities may become increasingly uncomfortable.
Why Shoulder Mechanics Matter
The shoulder functions much like a carefully coordinated team.
The rotator cuff, shoulder blade, collarbone, upper back, and neck all contribute to smooth movement.
If one part of the system isn’t functioning properly, other structures must compensate.
For example:
- Poor posture may alter shoulder blade movement.
- Weak stabilizing muscles may increase stress on the rotator cuff.
- Restricted upper back mobility may change how the shoulder moves overhead.
Over time, these altered movement patterns may reduce the available space beneath the acromion and contribute to repeated irritation.
This is one reason successful treatment often extends beyond the shoulder itself.
Is Shoulder Impingement the Same as a Rotator Cuff Tear?
No.
Although the two conditions may occur together, they are not the same.
Shoulder impingement describes a mechanical problem in which tissues become irritated during movement.
A rotator cuff tear refers to damage involving one or more of the rotator cuff tendons.
Many patients with shoulder impingement do not have a torn rotator cuff.
Likewise, some individuals with rotator cuff tears experience little or no pain.
A careful examination helps distinguish between these and other shoulder conditions so that treatment can be tailored appropriately.
How Doyle Chiropractic Treats Shoulder Impingement
Although the pain is felt in the shoulder, successful treatment often involves much more than the shoulder alone.
Shoulder impingement frequently develops because the entire shoulder complex is no longer moving efficiently. Changes in posture, muscle balance, shoulder blade movement, upper back mobility, or rotator cuff strength may all contribute.
That is why treatment begins with understanding why the impingement developed, not simply where the pain is located.
During your examination, Dr. Geoffrey Doyle evaluates:
- Shoulder range of motion
- Rotator cuff strength
- Shoulder blade mechanics
- Joint mobility
- Cervical spine function
- Thoracic spine mobility
- Posture
- Functional movement patterns
- Neurological findings
- Whether imaging or orthopedic referral is appropriate
Once the underlying contributors have been identified, an individualized treatment plan is developed.
Chiropractic Adjustments
Normal shoulder function depends on coordinated movement throughout the neck, upper back, ribs, shoulder blade, and shoulder joint.
When appropriate, chiropractic adjustments help restore healthy motion within these regions, allowing the shoulder to move with better mechanics and less unnecessary stress.
Improving thoracic spine mobility is often an overlooked but important component of treating shoulder impingement.
Class IV Laser Therapy
Inflammation of the rotator cuff tendons or surrounding bursa frequently contributes to shoulder impingement symptoms.
Class IV laser therapy delivers therapeutic light energy into these irritated tissues to support the body’s natural healing response.
Many patients find that reducing inflammation allows them to move more comfortably while progressing through rehabilitation.
Soft Tissue Therapy
As shoulder mechanics become abnormal, surrounding muscles often tighten in an attempt to stabilize the joint.
Manual therapy and other soft tissue techniques may help:
- Reduce muscle guarding
- Improve tissue mobility
- Improve circulation
- Restore flexibility
- Improve overall shoulder movement
These treatments often complement chiropractic adjustments and therapeutic exercise.
Therapeutic Exercise
Long-term improvement depends on restoring efficient movement rather than simply eliminating pain.
Depending on your diagnosis, rehabilitation may focus on improving:
- Rotator cuff strength
- Shoulder blade stability
- Postural control
- Thoracic mobility
- Flexibility
- Functional overhead movement
Exercises are progressed gradually to improve strength, coordination, and endurance while helping reduce the likelihood of future flare-ups.
The Dr. Doyle Perspective
“When patients hear the word ‘impingement,’ many imagine that something is permanently pinched inside the shoulder. In reality, I often explain that it’s more like a movement problem than a space problem. When the shoulder begins moving more efficiently again, many patients notice they can raise their arm with far less discomfort. That’s why I focus just as much on improving mechanics as I do on calming inflammation.”

Our Clinical Experience
One of the encouraging aspects of shoulder impingement is that many patients experience meaningful improvement once normal movement patterns begin to return.
In our practice, we’ve found that treatment is most successful when patients understand that recovery involves more than resting the shoulder. Strengthening the rotator cuff, improving shoulder blade control, increasing upper back mobility, and correcting postural habits all contribute to better long-term function.
Patients who actively participate in rehabilitation frequently report not only less pain, but smoother, more confident shoulder movement during work, exercise, and everyday activities.
When Should You Seek Prompt Medical Evaluation?
Although shoulder impingement often responds well to conservative care, certain symptoms require timely evaluation.
Seek prompt medical attention if you experience:
- Sudden inability to lift your arm following an injury
- Significant shoulder deformity
- Rapidly worsening weakness
- Persistent numbness or tingling into the arm or hand
- Severe pain following a fall or direct trauma
- Shoulder pain accompanied by fever or unexplained swelling
These findings may indicate a more serious injury requiring additional imaging or orthopedic consultation.
Frequently Asked Questions
Can shoulder impingement heal without surgery?
Yes. Many cases improve with appropriate conservative treatment that addresses inflammation, movement mechanics, muscle strength, and posture. Surgery is typically reserved for patients who do not improve with appropriate care or who have other significant structural problems.
Is shoulder impingement the same as bursitis?
Not exactly. Bursitis refers to inflammation of the bursa, while shoulder impingement describes a mechanical process that may irritate the bursa, rotator cuff tendons, or both. The conditions often occur together.
Should I stop exercising if I have shoulder impingement?
Not necessarily. Some exercises may temporarily aggravate symptoms, while others are an important part of recovery. An examination helps determine which activities should be modified and which exercises will support healing.
Will I need an MRI?
Not always. Many cases can be accurately evaluated through a detailed history and physical examination. Advanced imaging is recommended when clinically indicated based on your symptoms, examination findings, or response to treatment.
