Shoulder pain at night is most often made worse by pressure from lying on the painful side and by positions in which the arm drops backwards or across the chest. Relief usually comes from sleeping on your back with a pillow under the elbow and forearm, or on the healthy side with the arm resting on a pillow in front of you. At any given time, shoulder pain affects 7–26% of adults.
Below we explain where night-time shoulder pain comes from, how to position your arm for sleep, what to do in the evening and when to see a doctor first.
In brief
- At any given time, 7–26% of adults have shoulder pain; it is more common in people over 40.
- At night: on your back with 1–2 pillows under the elbow, or on the healthy side with the arm on a pillow.
- Shoulder pain with chest pain and shortness of breath requires calling for help – 112.
- A physiotherapy consultation in Rydułtowy costs 180 PLN, no referral needed.
- The clinic offers private visits only (not covered by NFZ, the Polish public health fund), Mon–Fri 7:00–20:00.

Why does the shoulder hurt more at night?
At night the shoulder is under pressure from body weight, and the stabilising muscles relax, so the head of the humerus settles into a position that irritates the rotator cuff tendons and the bursa. On your back, the arm drops backwards; on the healthy side, it falls across the chest. When you are still and without everyday distractions, pain is also simply more noticeable.
Night pain most often accompanies rotator cuff overload or injury, subacromial impingement, calcific deposits in the tendons and frozen shoulder, in which night pain can be particularly troublesome. If your shoulder also hurts when you raise your arm, read our post shoulder pain when raising the arm.
When should you see a doctor first?
See a doctor first – and in an emergency call 112 – if shoulder or arm pain comes with chest pain, shortness of breath or sweating, if it started after a fall and you cannot lift your arm, if the shoulder is hot and swollen with a fever, and also with constant night pain regardless of position and weight loss.
The following also need urgent assessment: a deformed shoulder after an injury, increasing weakness or numbness in the hand, a history of cancer, and right shoulder pain combined with abdominal pain. Always take left shoulder pain seriously in a person with heart disease.
How to position your arm for sleep?
The position that irritates the shoulder least is one in which the arm is slightly away from the body and supported in front. On your back, put a pillow under the elbow and forearm so that the elbow does not drop lower than the shoulder. On the healthy side, hug a large pillow and rest the painful arm on it. Avoid sleeping with your arm under or above your head.
- On your back. A folded towel or pillow under the elbow and forearm, hand resting on your stomach.
- On the healthy side. A large pillow in front of your chest, with the painful arm resting on it at shoulder height.
- Half-sitting. With severe pain, a raised headboard or several pillows behind your back help.
- On the painful side – no. Pressure increases the pain and worsens sleep.
What to do in the evening to fall asleep more easily?
Before bed, gentle movement that relaxes the shoulder helps, e.g. the pendulum exercise, as does avoiding heavy work with your arms above your head in the second half of the day. Some people feel relief after a warm shower, others after brief cooling through a towel. Take painkillers as recommended by a doctor or pharmacist, not on your own initiative.
Pendulum exercise: rest your healthy arm on a table, lean your body forward and let the painful arm hang freely. Swing it gently forwards and backwards, then make small circles – 1–2 minutes, once before bed. The movement should come from swaying your body, not from working the shoulder.
If the pain gets worse or spreads, stop the exercise and consult a physiotherapist.
How can a physiotherapist help?
The physiotherapist checks range of motion, strength and shoulder tests, as well as the cervical spine, to establish the source of the pain. They then choose manual therapy, exercises that gradually load the tendons and sleeping positions, and supporting treatments if needed. When the picture is unclear, they refer you to an orthopaedic doctor for imaging.
The therapy plan depends on the cause: a frozen shoulder is managed differently from tendon overload. You can read more about shoulder diagnosis and treatment on the shoulder and elbow page.

Good to know: bring any shoulder ultrasound or X-ray reports you have to the visit – even if they are a few years old.
Summary
Night-time shoulder pain is made worse by pressure and by the arm dropping backwards or across the body. Sleep on your back with a pillow under the elbow or on the healthy side with the arm on a pillow, and do a gentle pendulum exercise before bed. Shoulder pain with chest pain or after a fall needs medical help first.
Frequently asked questions
Does night-time shoulder pain mean a frozen shoulder?
Not always. Night pain is typical of a frozen shoulder, but it also often occurs with rotator cuff overload, calcific deposits in the tendons or subacromial impingement. A frozen shoulder is marked by clearly restricted movement in all directions, even when someone else moves the arm. An examination by a physiotherapist or doctor settles it.
Ice or heat for a painful shoulder at night?
There is no single rule. After a recent overload or injury, many people tolerate brief cooling through a towel better, while with long-standing stiffness and muscle tension heat helps, e.g. a warm shower before bed. Choose whatever actually reduces the pain, and do not fall asleep with a hot-water bottle or a compress placed directly on the skin.
Can left shoulder pain at night come from the heart?
Yes, pain spreading to the left shoulder or arm can be a symptom of a heart attack, especially when it comes with chest pressure, shortness of breath, sweating or nausea. Heart pain usually does not change when you move your arm. In such a situation, do not wait until morning – call 112.
Do I need a referral to see a physiotherapist with shoulder pain?
You do not need a referral for a private visit to a physiotherapist. Imaging, such as a shoulder ultrasound, is not necessary before the first visit, but if you have it, bring the reports. If the history or examination suggests a torn tendon or another problem that needs diagnosis, the physiotherapist will suggest an orthopaedic consultation.
