When to worry about pain when lifting the arm with a rotator cuff tear

A rotator cuff tear can affect the tendons that help lift and rotate the shoulder. Pain may appear during reaching, dressing, placing an object overhead, or lowering the arm. Weakness can be more telling than pain alone, especially after a fall or forceful pull. Some tears develop gradually, while others follow an injury. An examination compares movement and strength and may identify stiffness or another shoulder problem that needs different care.

Stop or modify activities that cause sharp pain, particularly heavy overhead work, but avoid keeping the shoulder completely still for long periods unless advised. Use supported, comfortable positions and keep the hand, wrist, and elbow moving. Arrange a clinical review if you cannot perform usual tasks, pain disturbs sleep, or weakness is progressing. Follow any prescribed rehabilitation plan and do not test the shoulder repeatedly by lifting heavy objects.

Get urgent assessment after trauma if you suddenly cannot raise the arm, the shoulder appears out of place, or numbness extends into the hand. Seek prompt help for marked swelling, a hot red joint with fever, or rapidly worsening pain. Emergency care is appropriate for chest pressure, breathlessness, faintness, or sweating with arm pain, because those symptoms may not come from the shoulder.

Ask whether the pattern suggests a tendon tear, stiffness, or another cause; whether imaging is needed; and which activities are safe. Discuss physiotherapy, pain control, sleep positioning, recovery expectations, and signs that should trigger an earlier review.
