Shoulder pain when lifting the arm can be caused by several common conditions:
- Rotator cuff injuries or tendinitis: Inflammation or irritation of the rotator cuff tendons due to overuse, injury, or poor technique can cause pain and tenderness especially when lifting the arm.
- Biceps tendinitis: Inflammation of the biceps tendon in the shoulder from repetitive motion or overuse can cause pain in the front of the shoulder radiating down the arm.
- Shoulder bursitis: Inflammation of the bursa sacs that cushion the shoulder tendons can cause pain and swelling, especially with movement.
- Shoulder impingement: This occurs when the space between the top of the shoulder bone (acromion) and the rotator cuff tendons narrows, pinching the tendons and bursa and causing pain when lifting the arm.
- Frozen shoulder: Thickening of the shoulder capsule restricting movement and causing pain with even small arm movements.
- Shoulder osteoarthritis: Loss of cartilage causing grinding of bones and pain that gradually worsens with movement.
- Rotator cuff tears: Can cause pain along with weakness and restricted movement.
- Other causes: Nerve injury, dislocation, separation, fractures, or cartilage tears may also cause shoulder pain when lifting the arm.
To manage mild shoulder pain:
- Rest and avoid actions that cause pain.
- Use ice packs.
- Take anti-inflammatory medications with food.
- Do gentle range of motion exercises (avoid long immobilization to prevent frozen shoulder).
- See a doctor if pain persists after a few weeks or if caused by injury.
Treatment varies by diagnosis and may include physical therapy, corticosteroid injections, or surgery in severe cases. Strengthening and mobility exercises help prevent future injury and pain.
