Why Is Rotator Cuff Pain Worse At Night?

Rotator cuff pain often worsens at night for different reasons; here are a few:

1. Reduced Blood Flow

When lying still, blood circulation to the shoulder can decrease, slowing down the delivery of oxygen and nutrients to the inflamed rotator cuff. This can make the area feel stiff and increase pain.

2. Compression from Sleeping Position

Sleeping on the affected shoulder can compress the rotator cuff tendons, intensifying pain. Even if you lie on the opposite side, your shoulder may still move into a position that strains or pinches the inflamed rotator cuff.

3. Increased Inflammation

During the day, the body’s natural movement helps distribute inflammation. At night, lying still can lead to the pooling of inflammatory fluids in the shoulder, leading to stiffness and discomfort.

4. Lack of Distraction

At night, without daily activities to distract you, you may notice pain more acutely, making it feel worse than during the day.

Tips to Alleviate Nighttime Rotator Cuff Pain

• Sleep Positioning – Use pillows to support your arm, keeping it slightly away from your body and elevated to reduce strain.
  
• Ice or Heat Therapy – Apply ice before bed to reduce inflammation or use heat to relax stiff muscles.
  
• Anti-Inflammatory Medications – Consult your doctor about taking NSAIDs or other pain relievers to reduce discomfort before bed.
  
• Gentle Stretching – Light stretching before bed can help reduce stiffness and ease inflammation.

If nighttime pain persists, call a local physical therapy clinic for personalized guidance.
