Shoulder pain at night: why it hurts lying down and how to sleep better
Why shoulder pain is often worse at night, sleeping positions that can help, and the signs that night pain needs to be checked by a doctor.
Shoulder pain that gets worse at night is common, and it is one of the main reasons people with a sore shoulder lose sleep. When you lie down the shoulder can be compressed, you notice pain more because there are fewer distractions, and positions you adopt in sleep can load an irritated tendon.
When to get urgent help
Call 999 straight away if shoulder or arm pain comes with any of these. Shoulder pain can sometimes be referred from the heart.
- Chest pain or pressure, breathlessness, sweating or feeling faint, particularly with pain spreading into the left arm, neck or jaw
- A shoulder that looks out of place or deformed after an injury
- Sudden loss of the ability to lift your arm after a fall
What it can feel like
- Aching in the shoulder or upper arm when you lie on that side, or sometimes on either side
- Waking when you roll onto the sore shoulder
- Pain with reaching overhead or behind your back during the day
- Difficulty finding a comfortable position
Common contributors
- Irritation of the rotator cuff tendons, often when load has risen faster than they can adapt
- A stiff or frozen shoulder
- Referred pain from the neck
- Poor sleep, stress and tiredness, which turn the pain up
- Less commonly, other problems that need medical review
General self-care
These are general comfort measures many people find reasonable. They are not a treatment plan, and what suits one person may not suit another.
- Place a pillow under or behind the sore arm so you do not roll onto the shoulder. An NHS trust leaflet suggests this
- Try lying on your back with a small pillow under the sore arm, or on your good side with a pillow hugged in front
- Keep the arm moving gently in the day. Resting it for too long can weaken the tendons
- Warmth before bed can make you more comfortable
- Paracetamol or ibuprofen can ease pain. Follow the packet instructions and ask a pharmacist if you are unsure
When to see your GP
See your GP promptly, or call NHS 111, if you have any of the following:
- Pain after a fall or significant injury
- A hot, red, swollen shoulder, especially with a fever
- Unexplained weight loss or constant night pain unrelated to position
Consider seeing your GP if:
- Night pain that happens whatever position you are in, or that is constant and getting worse
- Pain in both shoulders with morning stiffness lasting more than 45 minutes, particularly if you are over 50
- Pain with fever, a hot red swollen shoulder, unexplained weight loss, or feeling generally unwell
Where an osteopath fits in
There is limited good-quality research showing that hands-on treatment changes the course of night-time shoulder pain, so I do not claim that osteopathy treats it.
What an osteopath can usefully do is work out whether the pain is coming from the shoulder itself or from the neck, advise on sleeping positions and daytime load, and guide a graded exercise plan. An NHS trust leaflet describes exercise as the main treatment for rotator cuff-related pain, with improvement often taking 12 weeks or more. If the assessment suggests you need your GP, a physiotherapist or a specialist instead, I will tell you.
If you would like your symptoms assessed, you are welcome to book an appointment. Osteopathic care is not right for everyone, and if something needs medical attention first, I will tell you.
Common questions
What is the best sleeping position for shoulder pain?
Avoid lying directly on the sore shoulder. Many people are more comfortable on their back or on the other side, with a pillow supporting the sore arm. An NHS trust leaflet suggests a pillow under or behind the arm to stop you rolling onto the shoulder.
Why is shoulder pain worse at night?
Lying down compresses the shoulder, fewer distractions make pain more noticeable, and tiredness amplifies it. If night pain is constant, happens whatever position you are in, or is getting worse, have it checked.
