Shoulder Pain When Lifting Arm: Causes & Physiotherapy
If you experience shoulder pain when lifting arm movements—such as reaching overhead, putting on a shirt, reaching into a cupboard, washing your hair, or exercising—you may be wondering what is causing it and whether physiotherapy could help.
Shoulder pain is common, but the reason behind it can vary considerably. The shoulder is a complex region involving several joints, muscles, tendons, and surrounding structures. Pain with movement may develop gradually from repetitive activity or appear following an injury.
Understanding where your shoulder hurts, which movements trigger your symptoms, and whether you are experiencing weakness or loss of movement can help a physiotherapist determine what may be contributing to the problem.
What Can Cause Shoulder Pain When Lifting Arm?
There isn't one single cause of shoulder pain when lifting arm movements. Several conditions and movement-related problems can produce similar symptoms.
Common possibilities include:
Rotator Cuff-Related Shoulder Pain
The rotator cuff is a group of muscles and tendons that helps stabilize and move your shoulder.
Rotator cuff-related pain may be noticeable when raising the arm, reaching overhead, lifting objects, or lying on the affected shoulder. Some people also notice weakness or discomfort during specific movements.
Subacromial Shoulder Pain
Structures around the shoulder can become sensitive or irritated, particularly during repeated overhead movements.
Pain may be felt around the front or outside of the shoulder and can become more noticeable as the arm is raised.
Shoulder Bursitis
Bursae are small fluid-filled structures that help reduce friction between tissues. When a bursa around the shoulder becomes irritated, certain movements can become painful.
However, shoulder pain cannot be diagnosed based on symptoms alone, and bursitis may occur alongside other shoulder conditions.
Frozen Shoulder
Frozen shoulder, also called adhesive capsulitis, typically causes both pain and progressive stiffness.
People may notice increasing difficulty reaching overhead, behind their back, or outward with the arm. Everyday activities such as getting dressed or reaching for a seatbelt may become difficult.
Biceps Tendon-Related Pain
The long head of the biceps tendon crosses the front of the shoulder. Irritation in this area can contribute to pain toward the front of the shoulder, particularly during lifting, reaching, or carrying activities.
Neck-Related Shoulder Pain
Not every painful shoulder originates from the shoulder itself.
The cervical spine and surrounding nerves can sometimes refer symptoms into the shoulder and arm. This is one reason a physiotherapy assessment may include examination of both the shoulder and neck.
Why Does My Shoulder Hurt Only When I Raise My Arm?
Pain that occurs during a particular part of shoulder elevation can provide useful information, but it does not necessarily identify one specific diagnosis.
A physiotherapist may assess:
Shoulder range of motion
Strength
Rotator cuff function
Shoulder blade movement
Neck mobility
Areas of tenderness
Activities that reproduce your symptoms
Your work, exercise, and daily movement patterns
Rather than relying on one test or symptom, the findings are considered together to better understand what may be contributing to your pain.
Shoulder Pain When Lifting Arm Above Your Head
Overhead movement requires coordinated movement between the upper arm, shoulder blade, surrounding muscles, and thoracic region.
If certain tissues are irritated, weak, overloaded, or not tolerating the activity well, reaching overhead may become uncomfortable.
This may be particularly noticeable during activities such as:
Reaching into a high cupboard
Washing or styling your hair
Putting on a shirt or jacket
Swimming
Weight training
Racquet or throwing sports
Performing repetitive overhead work
The appropriate treatment depends on the underlying problem rather than simply the location of the pain.
Can Physiotherapy Help With Shoulder Pain?
Physiotherapy can help assess musculoskeletal shoulder pain and determine which movements or structures may be contributing to your symptoms.
Depending on your assessment, a physiotherapy treatment plan may include:
Education about your condition and activity modification
Range-of-motion exercises
Progressive strengthening
Rotator cuff exercises
Shoulder blade and postural exercises
Manual therapy when appropriate
Gradual return to work, exercise, or sport
Treatment should be individualized because two people experiencing similar shoulder pain may have different contributing factors and rehabilitation needs.
Should I Exercise a Painful Shoulder?
It depends.
Complete rest is not always necessary for musculoskeletal shoulder pain, but repeatedly forcing a painful movement is not necessarily helpful either.
A physiotherapist can help determine which activities can be continued, which may need temporary modification, and how exercises can be progressed based on your symptoms and function.
When Should I Have Shoulder Pain Assessed?
Consider having your shoulder assessed if the pain is persistent, interfering with everyday activities, limiting your movement, or accompanied by noticeable weakness.
Seek prompt medical attention for severe pain following significant trauma, an obvious deformity, sudden inability to move the arm, or other concerning symptoms.
