How common is pain when lifting the arm in rotator cuff tear?

A rotator cuff tear can make lifting the arm painful because the injured tendon cannot transfer force smoothly to the shoulder. Pain may occur overhead or when reaching behind the back. Weakness, difficulty dressing, and pain at night may accompany it. A sudden tear after a fall or forceful lift can feel different from gradually developing symptoms.

Arm-lifting pain alone does not establish a tear. Tendinitis, bursitis, shoulder impingement, arthritis, and neck-related nerve irritation can look similar. Assessment commonly considers the injury mechanism, active and assisted movement, strength, and tenderness. Ultrasound or MRI may be discussed when the result would change treatment.

Avoid heavy lifting and repeated overhead activity while keeping the shoulder within a tolerable range. Do not force a weak arm through resistance. Arrange clinical review if weakness persists, daily tasks are becoming difficult, or symptoms followed an injury. A planned rehabilitation programme may restore movement and strength, depending on the tear and your goals.

Seek prompt care after a fall or sudden load if you cannot raise the arm, the shoulder looks deformed, or pain is severe. Emergency assessment is also appropriate with chest pressure, breathlessness, new arm numbness, a cold or pale hand, or rapidly increasing swelling.

Ask: Do I have measurable weakness as well as pain? Could imaging distinguish a tear from tendon irritation? What lifting limits should I follow? Would physiotherapy be appropriate, and which changes should trigger urgent review?
