Shoulder pain and stiffness can significantly impact daily activities such as dressing, reaching, or sleeping comfortably. While frozen shoulder, or adhesive capsulitis, is a commonly cited cause of these symptoms, it is not the only potential culprit. Proper diagnosis is crucial as different conditions require distinct treatments.
Frozen shoulder occurs when the capsule surrounding the shoulder joint thickens and tightens, leading to restricted movement and persistent pain. However, other conditions like tendon injuries, arthritis, and nerve issues can mimic these symptoms.
Identifying frozen shoulder involves assessing the shoulder’s independent movement versus when another person moves it. With frozen shoulder, mobility is restricted in both scenarios. In contrast, a rotator cuff injury may limit a person’s ability to lift their arm independently but allow greater movement when assisted, suggesting weakness rather than stiffness.
Persistent shoulder pain can also stem from various other causes. A rotator cuff injury involves damage to the muscles and tendons stabilizing the shoulder, causing pain and difficulty in arm movement. Arthritis, whether due to wear and tear or other forms, can lead to joint damage, pain, and stiffness. Calcific tendinitis results from calcium deposits in shoulder tendons, causing intense pain without prior injury. Nerve issues originating in the neck can also radiate pain to the shoulder, often accompanied by tingling or numbness.
Other potential causes include labral injuries or shoulder instability, which affect the cartilage around the shoulder socket, and issues with the acromioclavicular joint at the top of the shoulder. Severe pain and visible deformity may indicate fractures or dislocations, while infections or inflammatory conditions could cause fever and swelling.
Medical advice should be sought if shoulder pain persists, disrupts sleep, or limits movement. Immediate care is essential if pain follows a serious injury, the joint appears deformed, or is accompanied by fever. Sudden shoulder pain with symptoms like chest pressure or breathlessness may signal a medical emergency.
Protecting shoulder health involves avoiding forced movements before understanding the cause of symptoms. Treatment plans may include activity modifications, exercises, pain management, and addressing underlying conditions. Accurate diagnosis is key to effective care, and persistent shoulder pain should not be automatically attributed to frozen shoulder.
