Shoulder Pain When Lifting Your Arm? It Could Be Rotator Cuff Tendinopathy
Does your shoulder pain when lifting arm, reach overhead, put on a jacket, or sleep on that side?
One possible cause is rotator cuff tendinopathy — a common shoulder problem involving the tendons that help control and stabilize the shoulder.
The pain can make everyday movements uncomfortable, but many rotator cuff-related problems can be managed conservatively. Understanding what is contributing to your symptoms is an important first step.
At OsteopathyNearMe in Etobicoke, we assess shoulder pain to understand how the shoulder, neck, upper back and surrounding muscles are moving and whether osteopathic care may be appropriate for you.
What Is the Rotator Cuff?
The rotator cuff is a group of four muscles and their tendons that surround the shoulder joint.
They help stabilize the shoulder and control movements such as lifting, reaching and rotating your arm.
When these tendons become sensitive or their ability to tolerate load is exceeded, pain can develop. This is commonly described as rotator cuff tendinopathy.
What Does Rotator Cuff Tendinopathy Feel Like?
Symptoms vary from person to person, but you may notice:
Pain when lifting your arm
Pain reaching overhead
Discomfort when reaching behind your back
Pain when lying on the affected shoulder
Pain during gym, work or sports activities
Reduced confidence or strength when using the arm
The discomfort is often felt around the front or outside of the shoulder and may sometimes travel into the upper arm.
What Causes Shoulder Pain When Lifting Arm?
There isn’t always one single cause.
Shoulder symptoms can develop after a sudden increase in physical activity, repetitive overhead work, sports, changes in training, or gradually without an obvious injury.
The shoulder also does not work in isolation.
Movement of the shoulder blade, upper back and neck can influence how comfortably the arm moves. Muscle tension, mobility restrictions and how much load the shoulder is currently able to tolerate may all be relevant.
This is why assessment is often more useful than focusing only on the exact spot where it hurts.
Do I Need an MRI for Shoulder Pain?
Not necessarily.
Current clinical guidelines emphasize that rotator cuff-related shoulder pain can often be assessed initially through your history and physical examination. Imaging is generally considered when there has been significant trauma, a more serious structural injury is suspected, or symptoms are not improving as expected.
An osteopathic assessment does not replace medical imaging when imaging is clinically necessary.
How Can an Osteopath Help With Rotator Cuff-Related Shoulder Pain?
Osteopathic care begins with understanding how your shoulder is moving and what may be contributing to your symptoms.
Assessment may include the shoulder joint itself as well as the shoulder blade, upper back, neck and surrounding muscles.
The goal of manual care may be to reduce discomfort, improve comfortable movement and make it easier to gradually return to normal activity.
Depending on your presentation, osteopathic care can also be used alongside other appropriate management, such as rehabilitation, medical assessment or other healthcare services.
Manual therapy is one conservative option used in the management of rotator cuff-related shoulder complaints, particularly as part of a broader rehabilitation approach.
What Techniques May an Osteopath Use?
Treatment is individualized rather than using the same technique for every painful shoulder.
Depending on the assessment, an osteopath may use:
Soft tissue techniques for muscles surrounding the shoulder and shoulder blade
Myofascial release to address areas of muscular and fascial tension
Gentle shoulder joint mobilization to support comfortable movement
Scapular mobilization to improve movement between the shoulder blade and rib cage
Thoracic spine mobilization when upper-back mobility may be influencing shoulder mechanics
Muscle energy techniques to work with mobility and muscular control
Trigger point techniques for relevant areas of muscular tension
Gentle cervical techniques when the neck may also be contributing to the presentation
The techniques used depend on your symptoms, examination findings and tolerance.
When Should Shoulder Pain Be Assessed?
Consider having your shoulder assessed if pain:
Keeps returning
Interferes with sleep
Makes overhead movement difficult
Limits work, exercise or sport
Has not improved over time
Is accompanied by noticeable weakness or loss of movement
Sudden severe pain after significant trauma, obvious deformity, major weakness, fever, unexplained systemic symptoms, or other concerning symptoms should receive appropriate medical assessment.
Shoulder Pain Assessment in Etobicoke
You do not necessarily need to wait until shoulder pain becomes severe before having it assessed.
At OsteopathyNearMe Health Studio in Etobicoke, we take a broader look at shoulder movement and the surrounding areas that may be contributing to your symptoms.
Osteopathic care may help make symptoms easier to manage and support your return to comfortable movement, either on its own when appropriate or alongside other healthcare and rehabilitation.
FAQ
Can rotator cuff tendinopathy heal?
Many people with rotator cuff-related shoulder pain improve with conservative management. Recovery time varies depending on the condition, duration of symptoms, activity demands and individual factors.
Why does my shoulder hurt when I raise my arm?
Rotator cuff-related pain is one possible explanation, but shoulder pain can have several causes. An assessment can help determine which structures and movements may be contributing.
Can an osteopath help with rotator cuff pain?
Osteopathic care may be used to help manage pain, mobility and muscular tension associated with shoulder complaints. Depending on the individual case, it may also complement rehabilitation or other healthcare.
Can shoulder pain come from the neck?
Yes. Some symptoms felt around the shoulder or upper arm can originate from or be influenced by the cervical spine. This is one reason an assessment may include both the shoulder and neck.
Do I need an MRI before seeing an osteopath?
Usually not. Current clinical guidelines do not recommend routine imaging to confirm rotator cuff tendinopathy during initial management unless specific circumstances make imaging appropriate.
