Shoulder Impingement / Bursitis
Overview
What Is Shoulder Impingement / Bursitis?
Shoulder impingement occurs when the tendons of the rotator cuff or the subacromial bursa become compressed between the bones of the shoulder during movement. This compression often leads to inflammation, irritation, and pain, particularly when lifting the arm overhead. When the bursa—a fluid-filled sac that cushions the joint—becomes inflamed, the condition is referred to as shoulder bursitis.
These two conditions frequently occur together because inflammation in the bursa can reduce the available space within the shoulder joint, worsening tendon compression. According to the American Academy of Orthopaedic Surgeons, shoulder impingement syndrome is a common cause of shoulder pain and often results from repetitive overhead motion or structural narrowing of the joint space.

Expert Analysis
Understanding Shoulder Impingement / Bursitis
The shoulder is a highly mobile joint supported by the rotator cuff muscles, tendons, ligaments, and bursae, which allow smooth and controlled arm movement. In shoulder impingement syndrome, the space between the acromion (the top of the shoulder blade) and the rotator cuff becomes narrowed. This causes the tendons and bursa to become pinched during arm movement.
Patients with shoulder impingement or bursitis commonly experience pain when lifting the arm overhead, weakness in the shoulder, tenderness in the front or side of the shoulder, and difficulty sleeping on the affected side. Over time, repeated irritation can lead to rotator cuff inflammation or tendon damage. If left untreated, chronic impingement may eventually contribute to tendon degeneration or rotator cuff tears.

Triggers
Shoulder impingement and bursitis are often caused by repetitive overhead movements that repeatedly compress the rotator cuff tendons and bursa within the shoulder joint. Activities such as swimming, baseball pitching, weightlifting, painting, or construction work frequently involve motions that place significant stress on the shoulder.
Other contributing factors include poor posture, muscle imbalance, rotator cuff weakness, bone spurs, joint degeneration, or previous shoulder injuries. The Cleveland Clinic explains that shoulder bursitis often develops when repetitive motion or structural changes within the joint cause inflammation of the cushioning bursa.

Differential Diagnosis
Many shoulder conditions can produce symptoms similar to shoulder impingement or bursitis. These include rotator cuff tears, biceps tendonitis, labral tears, shoulder arthritis, adhesive capsulitis (frozen shoulder), cervical radiculopathy, or nerve compression originating in the neck.
At Compass Pain and Wellness, accurate diagnosis is the most important step in effective treatment. Our physicians use structure-specific diagnostic ultrasound imaging, flexion and extension X-rays, MRI scans, nerve conduction studies, and targeted diagnostic injections to identify the exact source of shoulder pain. By pinpointing whether symptoms originate from the rotator cuff, bursa, joint capsule, or surrounding nerves, we can create a treatment plan designed specifically for your condition. A precise diagnosis allows us to treat the root cause rather than simply masking symptoms.
Solutions
At Compass Pain and Wellness, our treatment approach focuses on reducing inflammation, restoring proper shoulder mechanics, and supporting the healing of damaged tissues. Because shoulder impingement and bursitis often involve multiple structures within the joint, treatment plans are individualized to address both the inflammation and the biomechanical factors contributing to the condition.
By combining regenerative medicine with targeted therapies and rehabilitation, we aim to restore pain-free movement and long-term shoulder stability.
