Shoulder pain when lifting your arm can be caused by impingement – a common condition where structures in the shoulder joint get pinched. Here, we review what impingement entails, why it occurs, what symptoms you should be aware of, and how you can relieve the discomfort and support sustainable recovery.
What is shoulder impingement?
Shoulder impingement means that soft tissues, often one of the rotator cuff muscle tendons or a bursa, get pinched in a narrow space under the acromion (shoulder blade ridge) when the arm is lifted. This leads to irritation and inflammation, causing pain and restricted movement, especially when lifting above shoulder height.
Common causes & risk factors
Overuse, repetitive lifting, working above shoulder height, and weakness in the scapular stabilizing muscles are common causes. Athletes in throwing sports, swimming, or racket sports, as well as individuals with repetitive overhead arm work, are often affected. Posture-related factors, such as rounded shoulders and a stiff thoracic spine, can reduce the space in the shoulder joint.
Symptoms
Typical symptoms include pain when lifting the arm out to the side or forward, especially when the arm is at an angle between 60 and 120 degrees from the body. The pain can be felt deep in the shoulder and sometimes radiates down the upper arm. Night pain and difficulty lying on the affected side are common.
When should you seek medical attention?
You should seek medical attention if the pain is persistent, if you experience significant functional impairment, or if the discomfort affects sleep and daily activities. Long-term problems can lead to secondary changes in muscles and tendons.
Recommended protectors & supports
Shoulder supports with compression can provide support and security during activity. Rehabilitation focusing on scapular stability, posture, and rotator cuff musculature is central. Adjusting load, avoiding provocative movements, and ergonomic adjustments are important parts of the treatment.
