- Mayo Clinic and OrthoInfo say a rotator cuff problem can cause a dull ache that is worse at night, especially when lying on the painful shoulder.
- Mayo Clinic says call 911 if shoulder pain comes with trouble breathing, chest tightness or sweating.

If your shoulder is fine all day but aches when you lie down, you are in good company. Night shoulder pain is one of the most common reasons people search for help. This guide pulls together what the American Academy of Orthopaedic Surgeons (OrthoInfo) and Mayo Clinic say about why shoulder pain gets worse at night, what to try, and when to see a doctor. We also read public patient discussions to see what people ask and what they say helped them, and we compare those stories with the official advice. This is general information, not a diagnosis.
1. Why Does Shoulder Pain Get Worse at Night?
Mayo Clinic says a rotator cuff injury can cause a dull ache in the shoulder that worsens at night, and that the pain may disturb sleep. OrthoInfo lists pain at rest and at night, especially when lying on the affected shoulder, as one of the most common symptoms of a rotator cuff tear. It says that over time the pain may become more noticeable at rest and no longer go away with medicine. A hospital orthopedic surgeon quoted by Hartford Hospital adds that when a shoulder is injured or inflamed, sleeping on that side can become painful quickly, and that arthritis flare-ups, bursitis, an unsupportive pillow or mattress, and your usual sleep position can all add to night pain.

2. Shoulder Pain at Night but Not During the Day
This pattern is common. During the day you keep the shoulder moving and your arm is supported. At night you may lie directly on it, and the arm position can stress the joint. Mayo Clinic notes that pain that comes from the shoulder joint often gets worse with arm or shoulder movement. It also lists rotator cuff injuries as a common cause, and says some rotator cuff injuries do not cause pain at all. OrthoInfo says rotator cuff tears can also cause weakness when lifting or rotating the arm, and a crackling sensation in some positions.
3. Common Causes of Shoulder Pain at Night
Mayo Clinic's list of shoulder pain causes includes bursitis, tendinitis, impingement, rotator cuff injury, frozen shoulder, osteoarthritis, rheumatoid arthritis, polymyalgia rheumatica, muscle strains, cervical radiculopathy (a pinched nerve in the neck), thoracic outlet syndrome and heart attack, among others. Mayo adds that work with a doctor is needed for an accurate diagnosis. OrthoInfo says most rotator cuff tears come from slow wear over time, and that people over 40 are at greater risk. Mayo Clinic says rotator cuff tears are most common in people older than 50 and in jobs or sports with repeated overhead motion, such as carpentry, painting, baseball, tennis and weightlifting.
4. Right Shoulder or Left Shoulder Pain at Night: Could It Be the Heart?
Mayo Clinic says certain conditions of the neck, chest or stomach can cause shoulder pain. These include nerve issues in the spine, heart disease and gallbladder disease. When pain is referred like this, it should not get worse when you move your shoulder. Its guidance on emergencies is not side-specific: call 911 or emergency medical help if shoulder pain comes with a hard time breathing, tightness in the chest or sweating.
5. Shoulder Pain at Night With Numbness in the Fingers
Numbness or tingling in the hand can point to a nerve problem, not just a muscle or tendon problem. Mayo Clinic's cause list includes cervical radiculopathy, brachial plexus injury and thoracic outlet syndrome, and OrthoInfo says a doctor may examine the neck to make sure shoulder pain is not coming from a pinched nerve. If you have numbness, tingling or arm weakness along with night pain, tell your doctor.
6. Shoulder Pain at Night Relief: What to Try
Mayo Clinic's self-care steps for minor shoulder pain are topical pain relievers first, nonprescription pain medicines if needed, rest from activities that cause or worsen pain, and an ice pack for 15 to 20 minutes a few times a day. It says self-care and a little time are often all that is needed. For sleep, the Hartford Hospital surgeon recommends sleeping on your back or the non-painful side, using a small pillow under your arm for support, choosing a supportive mattress and pillow, trying a heating pad or ice pack before bed, and doing gentle stretches in the evening. Side sleepers who constantly lie on the same shoulder may switch sides or use a body pillow, and stomach sleeping twists the neck and shoulders and is best avoided.
For rotator cuff problems, Mayo Clinic says physical therapy exercises can improve flexibility and strength of the muscles around the shoulder, and for many people these exercises are all that is needed. OrthoInfo says nonsurgical treatment relieves pain and improves function in about 80 to 85 percent of patients with rotator cuff tears, and that treatment may include rest, activity modification, anti-inflammatory medicine, physical therapy and sometimes a steroid injection. Check with your doctor before starting an exercise program or taking medicine.

7. When to See a Doctor
- Call 911 if shoulder pain comes with a hard time breathing, chest tightness or sweating (Mayo Clinic).
- Get urgent care after a fall or accident if the shoulder looks deformed, you cannot move your arm away from your body, you have intense pain or sudden swelling (Mayo Clinic). See your care team right away if you have immediate arm weakness after an injury.
- Make an appointment if you have swelling, redness, tenderness and warmth around the joint, pain that is getting worse, or a harder time moving your shoulder (Mayo Clinic). The Hartford Hospital surgeon adds to call if the pain does not improve with home care or is severe or regularly wakes you up.
- OrthoInfo says chronic shoulder and arm pain are good reasons to see your doctor, because early treatment can prevent symptoms from getting worse and a rotator cuff tear can get larger over time.
8. What People Say and Ask in Patient Discussions
We read public discussions, including a Mayo Clinic Connect thread titled "best pillow for nerve impingement in shoulder" (August 2024), a "Shoulder pain" thread on the Permies personal care forum (2021), and the snippet of a Patient.info community post, "Chronic shoulder pain, finding it hard to cope" (2020). These are personal stories, not medical evidence, and we do not copy anyone's words or names.
- "What is the best pillow and sleeping position?" On Mayo Clinic Connect, a member with a stiff, painful shoulder asked exactly this. One reply said they sleep on their back with a pillow under their knees and place a tightly rolled towel along the side of the torso, pressed under the arm, adjusting thickness until the pain eases. Another suggested a nursing pillow to support both shoulders while sitting and reading. This matches the Hartford Hospital advice to support the arm with a small pillow.
- "Hot water helps but only while I am in the shower." The Permies poster said the pain was far less when sitting and that liniments and aspirin did little. Several replies suggested seeing a physical therapist, noting that rotator cuff trouble and neck or back problems can both cause shoulder pain. Mayo Clinic says the same: shoulder pain can have causes outside the shoulder.
- "Did physical therapy actually help?" Members said it helped a lot, but that the pain came back if they stopped doing the exercises. One said changing the pillows and sleeping position took pressure off and sped recovery. This fits Mayo Clinic's note that physical therapy exercises are all that many people need.
- "My X-rays and doctor visits showed nothing, but it still hurts." One member described repeated visits without a clear answer before therapy helped. OrthoInfo says imaging such as X-rays, MRI or ultrasound is used to confirm a diagnosis, and that X-rays are mainly used to rule out other causes such as arthritis. If you are not getting answers, ask about next steps or a specialist.
- "I am struggling to cope with the pain." Some posters described stretching and hot baths and the strain of living with pain. If pain or poor sleep is wearing you down, talk with your doctor.
9. Simple Sleep and Comfort Items
These products are only for comfort and positioning. They do not treat the cause of shoulder pain. Ask your doctor before using heat or cold if you have diabetes, poor circulation or numbness, because it can be harder to notice burns or frostbite. Follow product instructions, and do not fall asleep on a heating pad unless the maker says it is safe.
