Sleeping Positions for Shoulder Pain: 4 Pain Relief Tips for a Good Night's Sleep

Nighttime shoulder pain is very common, especially in people over 40, office workers, athletes, or those who frequently carry heavy loads. Many studies show that shoulder pain is one of the leading causes of sleep disturbance in adults, often causing patients to wake up frequently, have difficulty turning over, and feel tired the next morning. When the pain lasts for many days, the quality of life and mobility also significantly decrease.

If you are looking for a suitable sleeping position for shoulder pain to alleviate discomfort, or want to know how to reduce shoulder pain while sleeping without worsening your condition, this article will help you. Tiptory will guide you through sleeping positions that help reduce pressure on the rotator cuff, how to use pillows correctly, and simple measures to improve nighttime shoulder joint pain so you can sleep well and recover better.

Part 1: The Best Sleeping Positions for Shoulder Pain

Tip 1: Use a pillow correctly when sleeping on your side

Sleep on the side not affected by shoulder pain

• If you usually sleep on your side, lie on your healthy shoulder instead of the painful shoulder or the side with a rotator cuff injury.
• This position helps reduce pressure on the shoulder joint, limits nighttime shoulder joint pain, and reduces aches and stiffness upon waking.
• Avoid lying directly on the painful shoulder as this can increase pressure on the rotator cuff tendons and muscles, causing the pain to linger or worsen.

Place a pillow between your knees to keep your body aligned

• Place a soft pillow between your knees when side sleeping to keep your spine, hips, and legs in alignment.
• Maintaining proper alignment helps reduce twisting force on the shoulders and back, thereby aiding in reducing shoulder pain during sleep and improving sleep quality.
• Choose a pillow with moderate thickness so that your knees are neither pressed too close nor too far apart.

Hug an extra pillow to support your arm

• Hug a pillow to your chest or place it under the arm of the painful side to provide natural support for your shoulder.
• This method helps prevent the arm from pulling down during sleep, reducing muscle tension and pressure on the shoulder joint.
• This is one of the sleeping positions for shoulder pain recommended by many rehabilitation experts to alleviate nighttime discomfort and aid the recovery process.

Tip 2: Place a pillow under your arm when sleeping on your back

Place a pillow under the painful arm

• When sleeping on your back, place a pillow under the arm and elbow of the painful shoulder to support the entire arm.
• This position helps reduce pressure on the rotator cuff tendons and muscles, thereby aiding in reducing shoulder pain during sleep and helping you sleep more comfortably.
• You only need to elevate your arm slightly; avoid elevating it too high as this can cause tension in the shoulder and neck.

Using a regular pillow can also be effective

• A regular sleeping pillow with appropriate softness and height is sufficient to support the arm.
• If the pillow is too low, the arm may not be adequately supported; if it's too thick or too firm, the shoulder may be placed in an unnatural position.
• Adjust the pillow's position so that the arm is completely relaxed and does not increase nighttime shoulder joint pain.

Maintain proper back-sleeping posture

• Keep your head, neck, and upper back aligned to reduce pressure on the shoulder area.
• Combining this with placing a pillow under the arm will help maintain a more stable sleeping position for shoulder pain, limit painful movements during sleep, and support the shoulder joint's recovery process.

Tip 3: Avoid lying on the painful shoulder or on your stomach

Do not lie on the side of the painful shoulder

• Avoid lying directly on the side of the painful shoulder as body weight will increase pressure on the shoulder joint and rotator cuff tendons.
• This can make nighttime shoulder joint pain more severe, and cause you to wake up easily or have difficulty falling back asleep.
• If you accidentally turn over during sleep, use pillows to help keep your body in a stable position.

Limit sleeping on your stomach

• Sleeping on your stomach can cause the shoulder to rotate inward and bear unnatural pulling forces, increasing stress on the muscles and tendons around the shoulder joint.
• In addition to the shoulder, this position can also easily cause neck and back pain, affecting sleep quality.
• If you are looking for a sleeping position for shoulder pain, sleeping on your back or on your healthy shoulder is generally a better choice.

Change your sleeping position gradually

• If you are accustomed to sleeping on your stomach or on the side of your painful shoulder, do not try to change immediately in one night.
• Start sleeping in the new position and use pillows to support your body, helping to prevent turning back to the old position during sleep.
• Maintaining this habit for a period will help your body adapt, aiding in reducing shoulder pain during sleep and improving long-term sleep quality.

Tip 4: Sleep in a semi-seated position for the first 2 days

Keep your upper body elevated after a recent injury

• For approximately the first 48 hours after experiencing shoulder pain or a rotator cuff injury, sleep in a semi-seated position instead of lying completely flat.
• This position helps reduce pressure on the shoulder joint, limits swelling, and aids in reducing shoulder pain during sleep.
• Try to keep your back and shoulders firmly supported to feel more comfortable throughout the night.

You can sleep in a recliner or use many pillows

• If you have a recliner, you can sleep in it with a moderate recline angle to reduce pressure on your shoulder.
• If sleeping in bed, use multiple pillows behind your back and under your shoulders to create a semi-seated position, which helps stabilize your body and limit movements that cause pain.
• Ensure your head, neck, and back are evenly supported to avoid aches in other areas.

Adjust bed if it has a head-raising function

• If using an adjustable bed, raise the head of the bed to a moderately reclined position.
• This is one of the sleeping positions for shoulder pain that helps reduce pressure on the rotator cuff and limits nighttime shoulder joint pain, especially during acute injury or post-surgery as directed by a doctor.

Part 2: Quick tips for reducing nighttime shoulder joint pain

Tip 1: Cold compress your shoulder before bed

Cold compress for about 15–20 minutes before bedtime

• Before going to bed, apply a cold compress to the painful shoulder for about 15–20 minutes to help reduce pain and swelling.
• Wrap an ice pack or cold compress bag with a thin towel before placing it on your shoulder to protect your skin and prevent frostbite.
• You can sit or lie down while applying the compress, as long as your shoulder is relaxed and well-supported.

You can use a shoulder cold compress wrap

• A specialized cold compress wrap fits snugly around the shoulder joint, helping to keep the cold pack in place and providing more comfort.
• Use it according to the manufacturer's instructions regarding cooling time and how to wear it for optimal effectiveness.
• This is a method that helps reduce shoulder pain during sleep, especially when the shoulder is swollen or has been recently injured.

Do not cold compress while sleeping

• Always remove the cold pack or compress wrap before going to sleep.
• Applying a cold compress for too long can damage the skin, reduce local blood circulation, and increase the risk of frostbite.

Prioritize cold compress within the first 48 hours after injury

• If nighttime shoulder joint pain occurs due to a recent minor injury, cold compresses are often recommended within the first 48 hours to control inflammation and swelling.
• After this period, when the swelling has subsided, you can switch to warm compresses to help relax muscles and improve shoulder joint flexibility if it suits your condition or as directed by a doctor.

Tip 2: Apply a warm compress after 48 hours to relieve shoulder pain

Only begin warm compresses after 48 hours

• Approximately 48 hours after an injury, you can switch from cold to warm compresses if the shoulder area is no longer significantly swollen.
• Warm compresses help relax muscles, increase blood circulation, and aid in reducing shoulder pain during sleep.
• Avoid applying warm compresses too soon after an acute injury, as heat can worsen inflammation and swelling.

Apply a warm compress for 15–20 minutes before bedtime

• Spend about 15–20 minutes applying a warm compress to the painful shoulder before sleep to help muscles and joints relax.
• This is a simple way to reduce stiffness and improve sleep quality, especially for those who frequently experience nighttime shoulder joint pain.

Choose a suitable warm compress method

• You can use one of the following methods:
  • Use a heating pad or heat pack wrapped around your shoulder.
  • Pour hot water into a heat-resistant bottle, wrap the bottle with a soft towel, and gently apply it to your shoulder.
  • Take a warm bath to help the muscles around your shoulder relax.
  • Soak a towel in warm water and wrap it around your bare shoulder.

Ensure safe temperature

• Use only a moderately warm temperature, not too hot, to avoid burns.
• If using a hot water bottle or heat pack, always wrap it with an extra layer of towel to reduce direct skin contact.
• If you feel burning, increased pain, or discomfort, stop the compress immediately and recheck the temperature before continuing.

Combine with an appropriate sleeping position

• After applying a warm compress, maintain the correct sleeping position for shoulder pain, such as lying on your back or on your healthy shoulder, to reduce pressure on the shoulder joint and maintain pain relief throughout the night.

Tip 3: Light exercises to support shoulder recovery

Maintain light exercises daily

• Proper exercise can help reduce pain, improve shoulder joint flexibility, and aid in reducing shoulder pain while sleeping.
• You should exercise during the day or early afternoon to help your body relax more by bedtime.
• If pain increases during or after exercise, stop the exercise and consult a doctor or physical therapist.

Prioritize guided stretching exercises

• Some gentle stretching exercises, such as cross-body stretches or pendulum exercises, can help improve range of motion and reduce shoulder stiffness.
• Perform slowly, without forcing the stretch beyond your body's tolerance.
• Individuals with rotator cuff injuries should be guided by a doctor or rehabilitation specialist to choose appropriate exercises.

Choose low-impact activities

• Walking or gentle swimming are forms of exercise that help maintain health and increase body flexibility without putting significant pressure on the shoulder joints.
• You can aim for about 30 minutes of activity per day if your health allows.
• Maintaining this habit not only supports shoulder recovery but also helps you sleep better and reduces nighttime shoulder joint pain.

Avoid movements that increase pressure on the shoulder

• Do not lift heavy objects while your shoulder is in pain or recovering.
• Limit exercises that involve supporting body weight with your hands, such as push-ups or some plank variations.
• Avoid repeatedly raising your arm high above your head, as this can irritate the rotator cuff tendons and cause prolonged shoulder pain.

Listen to your body during exercise

• Mild pain during stretching may be acceptable, but intense or prolonged pain after exercise is a sign that the exercise program needs adjustment.
• Combining appropriate movement with the correct sleeping position for shoulder pain and other pain relief methods will help the recovery process be more effective.

Tip 4: Limit shoulder movement at night

Rest your shoulder while sleeping

• Nighttime is when the body recovers, so limit unnecessary movements to reduce pressure on the shoulder pain and support the healing process.
• While appropriate daytime exercise can be beneficial, too much activity before or during bedtime can worsen nighttime shoulder joint pain.
• Maintaining the correct sleeping position for shoulder pain will help the shoulder relax and reduce the risk of waking up due to pain.

Avoid activities that strain your shoulder in the evening

• In the few hours before bedtime, you should limit:
  • Lifting or carrying heavy objects.
  • Performing high-intensity shoulder exercises.
  • Overstretching the shoulder.
  • Movements that involve raising the arm above the shoulder repeatedly.
• Reducing the load on your shoulder joint in the evening can help reduce shoulder pain while sleeping and improve sleep quality.

Follow your doctor or physical therapist's instructions

• If your doctor or physical therapist has instructed you to perform exercises before bedtime, follow the prescribed frequency, duration, and technique.
• Do not add new exercises or increase intensity without professional advice, especially if your shoulder is still swollen, painful, or has limited movement.
• If pain increases or you experience significant shoulder weakness after exercise, stop and contact your doctor for reassessment.

Tip 5: Take pain medication before bed

Consider using over-the-counter pain relievers

• If shoulder pain makes it difficult to sleep, you can consider taking over-the-counter pain relievers before bedtime to improve comfort.
• Some commonly used medications include:
  • Acetaminophen (paracetamol).
  • Ibuprofen.
  • Naproxen.
• These medications can help reduce shoulder pain while sleeping, thereby improving sleep quality during acute or recurrent pain.

Take medication at the right time and dosage

• It is best to take medication approximately 20–30 minutes before bedtime to allow it time to take effect.
• Always follow the dosage and instructions on the packaging or as directed by your doctor or pharmacist.
• Do not self-increase the dose or take multiple pain medications simultaneously without consulting a healthcare professional.

Important notes when using pain relievers

• Ibuprofen and naproxen belong to the group of non-steroidal anti-inflammatory drugs (NSAIDs) and may not be suitable for individuals with stomach ulcers, gastrointestinal bleeding, kidney disease, heart failure, or allergies to this drug class.
• Acetaminophen (paracetamol) generally causes less stomach irritation, but it is important to avoid exceeding the maximum recommended dose to limit the risk of liver damage.
• If nighttime shoulder joint pain persists for many days, worsens, or requires frequent pain medication to sleep, you should visit a medical facility to determine the cause and receive appropriate treatment instead of merely managing symptoms.

Part 3: How to sleep well with shoulder pain

Tip 1: Maintain a regular sleep schedule

Go to bed and wake up at the same time every day

• Try to go to bed and wake up at the same time, even on weekends.
• This habit helps stabilize your body clock, making it easier to fall asleep and sleep more deeply.
• For people with shoulder pain, a regular sleep schedule also contributes to reducing shoulder pain while sleeping by improving sleep quality and supporting the body's recovery process.

Get enough sleep to support rotator cuff recovery

• During rotator cuff injury treatment or recovery, sleep plays a crucial role in tissue regeneration and inflammation reduction.
• Recommended sleep duration by age:
  • Adults: 7–9 hours per night.
  • Teenagers: 8–10 hours per night.
  • Children: 9–11 hours per night.
• Sufficient sleep combined with a suitable sleeping position for shoulder pain will help reduce nighttime shoulder joint pain and improve mobility the next day.

Build habits that promote better sleep

• Limit the use of phones or electronic devices right before bedtime.
• Keep your bedroom quiet, dark, and at a comfortable temperature.
• Maintain relaxing habits like reading or slow breathing to help your body fall asleep easier.
• If pain frequently wakes you up despite trying various measures, consult your doctor for evaluation and treatment of the underlying cause.

Tip 2: Wear an arm sling if necessary

Use an arm sling to limit shoulder movement

• If your doctor recommends it or your shoulder needs immobilization during recovery, you can wear an arm sling while sleeping.
• The sling helps limit involuntary movements during sleep, thereby reducing pressure on the shoulder joint and aiding in reducing shoulder pain while sleeping.
• Keeping the shoulder stable can also help reduce nighttime shoulder joint pain, especially after injury or surgery.

Wear the sling correctly

• You can purchase an arm sling at a pharmacy or medical supply store.
• Wear it according to the manufacturer's instructions so that your arm is supported in a natural position, neither too loose nor too tight.
• If the sling causes numbness in your hand, increased pain, or hinders blood circulation, adjust it or stop using it and consult a doctor.

Prioritize your doctor's instructions

• If your doctor has prescribed wearing an arm sling at night, adhere to the advised duration and method of use.
• Do not wear a sling for an extended period without medical indication, as prolonged immobilization of the shoulder joint can increase the risk of joint stiffness and muscle weakness.
• Combining the sling with a suitable sleeping position for shoulder pain and expert-guided rehabilitation exercises will help the recovery process be more effective.

Tip 3: Choose the right mattress to reduce shoulder pain

Consider changing your mattress if shoulder pain persists

• Most cases of rotator cuff injury can improve within 4–6 weeks with proper treatment and rest.
• However, if nighttime shoulder joint pain is persistent, frequently recurs, or worsens when lying down, your current mattress may be a contributing factor to discomfort.
• A suitable mattress will help maintain the sleeping position for shoulder pain, reduce pressure on the shoulder, and improve sleep quality.

Prioritize a medium-firm mattress

• A medium-firm mattress is usually a suitable choice because it supports the spine and shoulder joints while distributing pressure on pressure points.
• A mattress that is too soft causes the body to sink deeply, leading to shoulder and spine imbalance.
• Conversely, a mattress that is too firm can put significant pressure on the shoulders, back, and hips, making shoulder pain worse when sleeping.

Try lying down before deciding to buy

• Spend a few minutes lying in your usual sleeping position to assess the support.
• If your body sinks too much or your shoulder is too deep in the mattress, it may be too soft.
• If you feel pressure and discomfort in your shoulders, back, or hips as soon as you lie down, the mattress may be too firm.

Try a firmer sleeping surface if needed

• If you suspect your current mattress is the reason why reducing shoulder pain while sleeping is not effective, you can try lying on a firmer surface for a short period to compare the feeling.
• Some people find that sleeping on a firmer surface provides better support for their shoulders and spine. However, this is not a one-size-fits-all solution.
• If the pain persists despite changing your mattress and adjusting your sleeping position, seek medical attention for an evaluation of the cause and to develop an appropriate treatment plan.

Tip 4: Only use sleep aids when absolutely necessary

Consider sleep aids only for severe insomnia

• If nighttime shoulder pain causes prolonged insomnia despite changing your sleeping position for shoulder pain and applying other pain relief measures, you may consider using over-the-counter sleep aids for a short period.
• Common active ingredients include diphenhydramine or doxylamine succinate.
• Medication should only be used when truly necessary and according to the manufacturer's instructions or a doctor's prescription.

Do not use sleep aids long-term

• Avoid using sleep aids continuously for more than 2 weeks without a doctor's instruction.
• Prolonged use can reduce the effectiveness of the medication, increase the risk of dependence, and cause drowsiness or reduced alertness the next day.
• If insomnia persists, you should identify the cause and treat the shoulder pain rather than relying solely on sleeping pills.

Discuss with your doctor if you are taking other medications

• Inform your doctor or pharmacist if you are using other medications or have underlying medical conditions.
• Some sleep aids can interact with other medications, increasing the risk of side effects or affecting treatment effectiveness.
• Elderly individuals and those with chronic diseases should exercise particular caution when using these medications.

Do not use alcohol to aid sleep

• Alcohol can make you fall asleep faster but often reduces sleep quality, causing you to wake up easily in the middle of the night.
• Combining alcohol with sleep aids can increase the risk of excessive drowsiness, respiratory depression, and other severe side effects.

Limit long naps

• If you regularly have trouble sleeping at night, limit naps to about 30–45 minutes.
• Napping for too long can reduce your feeling of sleepiness in the evening, making it harder to achieve shoulder pain relief during sleep and maintain deep sleep.
• Combining a regular sleep schedule, light exercise during the day, and pain management will help improve sleep quality sustainably.

Tip 5: See a doctor if shoulder pain causes prolonged insomnia

Do not delay seeing a doctor

• If nighttime shoulder pain consistently disrupts your sleep or causes fatigue, reduces work performance, and affects daily activities, proactively seek medical attention.
• During the examination, clearly describe:
  • When the pain started.
  • The intensity and location of the pain.
  • Which sleeping positions with shoulder pain increase or decrease the pain.
  • The insomnia and any measures you have tried that were not effective.
• This information will help the doctor determine the cause and select an appropriate treatment method.

May be prescribed pain relievers or sleep aids

• Depending on the extent of the injury, the doctor may prescribe stronger pain relievers or anti-inflammatory drugs than over-the-counter options.
• In some cases of severe insomnia due to shoulder pain, the doctor may consider using sleep aids for a short period.
• Medication use needs to be monitored to ensure safety and minimize side effects.

Pain injections when necessary

• If the pain persists or does not respond to conventional treatments, the doctor may order injections into the shoulder joint to temporarily reduce inflammation and pain.
• This measure can help you sleep better and facilitate the rehabilitation process.
• The effect of injections only lasts for a certain period and does not replace treatment of the underlying cause.

Physical therapy helps restore shoulder function

• The doctor may refer you to a physical therapist to develop an appropriate exercise program.
• Properly guided exercises can help reduce pain, improve range of motion, and increase muscle strength around the shoulder joint.
• This is one of the important treatment methods to reduce shoulder pain during sleep and prevent long-term recurrence.

Surgery in severe cases

• If the rotator cuff injury is severe or conservative treatments are ineffective, the doctor may consider surgery.
• Depending on the specific condition, surgery may aim to:
  • Remove bone spurs causing impingement.
  • Repair torn rotator cuff tendons.
  • Replace the shoulder joint if it is severely damaged.
• After surgery, patients often need to combine rehabilitation to regain mobility and improve sleep quality.
