Waking up with shoulder pain, especially when you’ve slept on your side is frustrating and surprisingly common. Many people assume it’s just the way they slept or that it will go away on its own, but recurring nighttime shoulder pain is often a sign that something deeper is going on.
The good news? Most causes of shoulder pain while sleeping are treatable with the right approach.
Common Reasons Your Shoulder Hurts at Night
1. Rotator Cuff Irritation
The rotator cuff is a group of muscles and tendons that help stabilize your shoulder. When irritated or weak, lying on the shoulder can compress these tissues, leading to pain, especially at night when muscles are relaxed.
2. Shoulder Impingement
Impingement occurs when shoulder structures get pinched during movement or sustained positions, such as side sleeping. This often causes pain when lying on the affected side or lifting the arm overhead.
3. Poor Sleeping Position
Sleeping with your arm tucked under your body or head can place excessive strain on the shoulder joint and surrounding muscles, limiting blood flow and increasing irritation overnight.
4. Postural Issues
Rounded shoulders or forward head posture during the day can alter how your shoulder sits in the joint. Over time, this makes the shoulder more sensitive to pressure when sleeping.
5. Referred Pain From the Neck
Sometimes shoulder pain doesn’t originate in the shoulder at all. Neck stiffness or nerve irritation can refer to pain into the shoulder, especially when lying down.
Why Shoulder Pain Often Feels Worse at Night
At night, muscles relax and inflammation can become more noticeable without daytime distractions. Lying still for long periods also reduces circulation, which can increase stiffness and discomfort.
What You Can Do Right Now
- Avoid sleeping directly on the painful shoulder
- Use a supportive pillow to keep your neck and shoulder aligned
- Try hugging a pillow to prevent the shoulder from rolling forward
- Avoid sleeping with your arm overhead or tucked underneath you
These adjustments can reduce pressure, but they don’t address the root cause.
How Physiotherapy Helps Shoulder Pain
Physiotherapy focuses on identifying why the shoulder is becoming irritated in the first place. Treatment may include:
- Improving shoulder and upper back mobility
- Strengthening the rotator cuff and surrounding muscles
- Addressing posture and movement habits
- Reducing inflammation and restoring normal joint mechanics
By treating the underlying issue, physiotherapy helps reduce nighttime pain and prevent it from returning.
When to Get It Checked
If shoulder pain:
- Wakes you up at night
- Lasts more than a week or two
- Gets worse when lying on it
- Limits your daily movement
It is worth seeing a physiotherapist at the Durham Orthopedic & Sports Injury Clinic.
