If you're waking because of shoulder pain or struggling to find a comfortable sleeping position, the underlying cause is often related to conditions such as rotator cuff tendinopathy, shoulder bursitis or frozen shoulder. The good news is that identifying the cause and starting the right treatment can significantly improve both your shoulder and your sleep.
At The Addison Physiotherapy, we regularly help people who are unable to sleep comfortably because of shoulder pain. Our goal is to identify the underlying condition, reduce irritation and restore normal shoulder function.
Key Takeaways
- Shoulder pain at night is commonly associated with rotator cuff injuries and shoulder bursitis.
- Sleeping on the affected shoulder often aggravates symptoms.
- Night pain doesn't automatically mean you've torn a tendon.
- Physiotherapy can help reduce pain and improve shoulder function.
- Most people recover without surgery.
What causes shoulder pain at night?
Several shoulder conditions can become more painful at night.
Common causes include:
- Rotator cuff tendinopathy
- Shoulder bursitis
- Partial rotator cuff tears
- Frozen shoulder
- AC joint irritation
Pain often becomes more noticeable at night because the shoulder is compressed when lying on your side, muscles relax during sleep, and there's less movement to naturally change positions.
In some cases, inflammation within the shoulder also contributes to increased discomfort overnight.
What are the symptoms of shoulder pain at night?
People commonly experience:
- Pain when lying on one side
- Waking because of shoulder discomfort
- Difficulty finding a comfortable sleeping position
- Pain reaching overhead during the day
- Pain putting on a shirt or jacket
- Morning stiffness
Night pain often develops alongside pain during lifting or reaching activities.
When should I see a physiotherapist?
It's worth booking an assessment if:
- Shoulder pain regularly wakes you at night.
- Symptoms have persisted for more than one to two weeks.
- You're avoiding normal activities because of pain.
- Your shoulder feels weaker or stiffer.
- Pain is gradually becoming worse.
Persistent night pain is a good reason to have your shoulder professionally assessed.
Do I need imaging?
Usually, no.
Many conditions that cause shoulder pain at night can be accurately diagnosed through a clinical assessment.
Imaging may be recommended if:
- There has been significant trauma.
- There is substantial weakness.
- Symptoms aren't improving with rehabilitation.
- A larger tendon tear is suspected.
Imaging findings don't always explain why pain is occurring, so treatment should always be based on both your symptoms and physical examination.
How is shoulder pain at night treated?
Treatment depends on the underlying cause, but generally focuses on reducing irritation while improving shoulder function.
Treatment usually includes:
Education
Understanding why your shoulder hurts at night and how to avoid aggravating positions.
Load Management
Reducing activities that excessively irritate the shoulder while maintaining comfortable movement.
Progressive Strengthening
Improving the strength of the rotator cuff and surrounding muscles to reduce stress on painful structures.
Sleeping Advice
Simple changes such as sleeping on your opposite side with a pillow supporting your arm or placing a pillow under the affected arm when lying on your back can often improve comfort.
Can I keep exercising?
Usually, yes.
Complete rest is rarely recommended.
Your physiotherapist may suggest temporarily modifying painful overhead exercises while continuing other forms of training.
Maintaining shoulder strength is an important part of recovery.
How long does recovery take?
Recovery depends on the condition causing your symptoms.
