Why does rotator cuff pain get worse at night?

The rotator cuff is a group of muscles and tendons that keep your shoulder stable and help you lift and rotate your arm. When these structures are inflamed, torn, or irritated, lying down can put pressure on them, triggering pain.

At night, several factors can make the pain feel worse:

• Lack of movement causes stiffness and inflammation buildup
  
• Sleeping on the affected shoulder compresses injured tissue
  
• Poor sleep posture strains shoulder muscles
  
• Lower levels of natural anti-inflammatories (cortisol) during the night
  

Common causes of nighttime rotator cuff pain

• Rotator cuff tendinitis (inflammation of the tendons)
  
• Rotator cuff tear (partial or full)
  
• Shoulder impingement syndrome
  
• Bursitis (inflammation of the bursa, a fluid-filled sac)
  
• Post-surgical healing
  

If pain continues for more than a few weeks, it’s important to consult a healthcare provider or physical therapist for proper diagnosis and treatment.

How to relieve rotator cuff pain at night: 10 tips that work

Here’s how to reduce pain and get more comfortable sleep:

1. Sleep in the right position

Your sleeping posture can make a big difference. Avoid lying on the affected shoulder, and try one of these positions instead:

✅ Sleep on your back with a pillow under your elbow to slightly elevate the arm
✅ Sleep on the opposite side with a pillow hugged to your chest and one between your knees
✅ Use a recliner or wedge pillow to keep your torso elevated if flat positions worsen the pain

2. Use a supportive pillow under your arm

Tucking a soft pillow or folded towel under the elbow of the affected arm helps reduce strain on the rotator cuff and keeps the shoulder in a neutral position.

3. Apply ice before bedtime

If inflammation is a factor, applying a cold compress to the shoulder for 15–20 minutes before bed can reduce swelling and dull the pain. Always wrap ice packs in a cloth to protect your skin.

4. Try heat therapy for stiffness

For chronic stiffness or muscle tightness, a heating pad or warm shower before bed can relax the muscles around the shoulder and improve blood flow.

5. Take pain relievers if needed

Over-the-counter medications like:

• Ibuprofen (Advil, Motrin)
  
• Acetaminophen (Tylenol)
  
• Topical creams (Voltaren, capsaicin)
  

can reduce pain and inflammation, helping you fall asleep more comfortably. Always consult a healthcare provider before prolonged use.

6. Perform gentle shoulder stretches

Before bed, try gentle rotator cuff exercises to reduce stiffness. Examples include:

• Pendulum swings
  
• Doorway stretches
  
• Crossover arm stretches
  

Avoid any motion that increases pain. A physical therapist can guide you on safe movements based on your condition.

7. Avoid overhead activity before bed

Avoid reaching, lifting, or overhead movements in the evening, especially if they trigger your shoulder pain. Give your shoulder time to rest before lying down.

8. Use a shoulder brace or sling (if advised)

Some patients benefit from wearing a light support brace or sling at night to limit motion and reduce strain. However, prolonged use without guidance can lead to stiffness, so check with a medical professional.

9. Establish a relaxing bedtime routine

Poor sleep can worsen pain perception. Create a calming bedtime routine with:

• Dim lighting
  
• Gentle breathing exercises
  
• Avoidance of screens before bed
  
• A comfortable, supportive mattress and pillows
  

Quality sleep supports your body’s natural healing process.

10. Consult a physiotherapist

A physiotherapist can:

• Diagnose the root cause of your shoulder pain
  
• Create a custom treatment plan including strengthening and mobility exercises
  
• Use manual therapy, ultrasound, or TENS to reduce pain and inflammation
  

When to see a doctor

If your pain:

• Wakes you up nightly
  
• Persists for more than 2–3 weeks
  
• Is accompanied by weakness or limited range of motion
  
• Follows an injury, fall, or trauma
  

…it’s time to seek professional care. You may need imaging (like ultrasound or MRI) and a more targeted treatment approach.

Final thoughts

Rotator cuff pain at night can be frustrating and exhausting—but you don’t have to suffer in silence. By making a few strategic changes to your sleep position, lifestyle, and treatment approach, you can ease discomfort and start sleeping better again.

If pain persists, don’t hesitate to talk to a physiotherapist or shoulder specialist. With the right care, healing is possible—and restful nights can return.
