Why does my shoulder hurt at night?

Night-time shoulder pain is common and can occur with several conditions, including rotator cuff problems, bursitis, frozen shoulder, arthritis, and shoulder inflammation.

Pain can become more noticeable at night because the shoulder remains in one position for longer periods and lying directly on the affected side can increase pressure on sensitive tissues.

Common causes include

• Rotator cuff tear or tendinopathy
• Shoulder bursitis
• Frozen shoulder
• Shoulder arthritis
• Impingement-related irritation
• Previous shoulder injury

Why lying down may make it worse

When you lie on the painful shoulder, pressure can increase around the inflamed tendons and bursa.

Even when lying on the opposite side, the unsupported arm can place tension on painful shoulder tissues.

What may help temporarily?

Depending on the cause:

• Avoid sleeping directly on the painful side
• Support the arm with a pillow
• Follow prescribed physiotherapy exercises
• Avoid repetitive painful overhead activity
• Use medicines only as advised

Persistent night pain should not automatically be assumed to be a rotator cuff tear because several shoulder conditions can cause similar symptoms.

Dr. Atul Mishra assesses shoulder movement, strength, tenderness, injury history, and imaging where required to identify the underlying cause rather than treating night pain alone.
