Most shoulder pain comes from muscles, tendons or the joint itself. But shoulder pain, especially in the left shoulder, arm, jaw or between the shoulder blades, can be a sign of a heart attack or angina. Heart-related shoulder pain usually comes with chest pressure, shortness of breath, sweating, nausea or dizziness, often starts with exertion, and does not change when you move or press on the shoulder.
Shoulder pain is one of the most common reasons people see a pain specialist. Rotator cuff problems, frozen shoulder, muscle strain and nerve pain from the neck account for the vast majority of cases. But because the heart and the shoulder share nerve pathways, a heart attack can sometimes show up as pain in the shoulder or arm rather than the chest.
Knowing the difference can save a life. This guide explains why the heart can cause shoulder pain, how to tell cardiac pain from musculoskeletal pain, and which symptoms mean you should go to hospital now.
Can shoulder pain be a sign of a heart attack?
Yes. Shoulder pain can be a symptom of a heart attack (myocardial infarction) or angina, which is chest pain caused by reduced blood flow to the heart. It is usually felt in the left shoulder and arm, but it can also appear in the right shoulder, both shoulders, the jaw, the neck or the upper back.
Shoulder pain on its own, without other symptoms, is far more likely to come from the shoulder itself. The concern is shoulder pain plus other warning signs, or shoulder pain that behaves like heart pain.
Why does a heart problem cause shoulder pain?
This is called referred pain. The nerves that carry pain signals from the heart enter the spinal cord at the same levels as nerves from the chest wall, left arm, shoulder and neck. The brain cannot always tell exactly where the signal started, so it may “feel” heart pain in the shoulder, arm or jaw instead.
The same mechanism explains why other organs can cause shoulder pain:
| Organ | Where pain may be felt |
| Heart | Left shoulder and arm, jaw, neck, between the shoulder blades |
| Gallbladder | Right shoulder or right shoulder blade, often after fatty meals |
| Lungs (including a blood clot) | Shoulder or shoulder blade, with breathlessness or pain on breathing |
| Diaphragm or spleen | Tip of the left shoulder, sometimes after abdominal injury |
How do you tell if shoulder pain is heart-related or muscular?
This comparison is a guide, not a diagnosis. If you are unsure, treat it as an emergency.
| Feature | More likely heart-related | More likely shoulder or muscle |
| What brings it on | Exertion (walking, climbing stairs), stress, cold, heavy meals | Specific arm movements, lifting, reaching overhead, lying on that side |
| Effect of moving the arm | No change | Worse with certain movements |
| Pressing on the area | Not tender | Often tender to touch |
| Type of pain | Pressure, squeezing, heaviness, tightness, burning | Sharp, aching, catching or pinching |
| Other symptoms | Chest discomfort, breathlessness, sweating, nausea, dizziness, unusual tiredness | Stiffness, weakness, clicking, reduced range of motion |
| What relieves it | Rest (angina) or nothing (heart attack) | Rest, ice or heat, changing position |
| Duration | Several minutes, comes in waves, or persistent | Linked to activity; can last days or weeks |
A key clue: pain you can reproduce by moving the shoulder or pressing on it is usually musculoskeletal. Pain that appears when you walk briskly and settles when you stop is a classic angina pattern and needs urgent assessment.
Warning signs:
Call 112 (or 108 for an ambulance) or go to the nearest emergency department if shoulder pain comes with:
- Chest pain, pressure, tightness or heaviness
- Pain spreading to the arm, jaw, neck, back or stomach
- Shortness of breath
- Cold sweat
- Nausea or vomiting
- Light-headedness, dizziness or fainting
- A sense of impending doom or unusual anxiety
- Sudden, unexplained fatigue
While waiting for help, sit down and rest, and do not drive yourself to hospital. Emergency teams may advise chewing aspirin if you are not allergic to it. Follow the advice of the emergency operator or a doctor.
Is left shoulder pain more serious than right shoulder pain?
Left shoulder and arm pain is the most commonly described pattern in heart attacks, but right shoulder pain does not rule out a heart problem. Heart pain can spread to either arm or both. Right shoulder pain can also come from the gallbladder or liver.
The side matters less than the pattern. Ask: is it linked to exertion, does it come with other symptoms, and is it unaffected by shoulder movement?
Can heart problems cause pain between the shoulder blades?
Yes. Pain, pressure or burning between the shoulder blades can be a symptom of a heart attack, and is reported more often by women. A sudden, severe, tearing pain between the shoulder blades can also signal an aortic dissection, a tear in the body’s main artery, which is a life-threatening emergency. It is one of several red flags in back pain that should never be ignored.
Upper back pain that comes from posture, muscle strain or the spine is far more common. It usually relates to movement and position. (Read more: middle and upper back pain causes.)
Heart attack symptoms in women: why shoulder pain matters
Women are more likely than men to have heart attack symptoms other than classic crushing chest pain. These include:
- Pain in the shoulder, upper back, neck or jaw
- Shortness of breath without chest pain
- Nausea, vomiting or indigestion-like discomfort
- Extreme fatigue, sometimes for days beforehand
- Dizziness or a cold sweat
Because these symptoms feel less dramatic, women are more likely to delay seeking help. If something feels wrong, get checked.
Silent heart attacks: who is at higher risk?
Some people have heart attacks with mild or unusual symptoms, or almost none at all. The risk is higher in:
- People with diabetes, as nerve damage can dull pain signals. People with diabetes are also more prone to stiff, painful shoulders, so it helps to know why frozen shoulder targets diabetics.
- Older adults
- Women
For these groups, unexplained shoulder or arm pain together with breathlessness, sweating or fatigue should be taken seriously.
Who is at higher risk of heart-related shoulder pain?
Your risk of heart disease is higher if you:
- Smoke or use tobacco
- Have high blood pressure, high cholesterol or diabetes
- Are overweight or physically inactive
- Have a family history of early heart disease
- Are a man over 45 or a woman over 55, although heart disease is increasingly seen in younger Indians
- Have chronic stress or poor sleep
If you have risk factors and develop new shoulder or arm pain with exertion, speak to a doctor even if the pain goes away with rest.
What is angina, and how does it feel in the shoulder?
Angina is chest discomfort caused by temporarily reduced blood flow to the heart muscle. It is a warning sign of coronary artery disease.
Stable angina typically:
- Comes on with exertion or emotional stress
- Feels like pressure or heaviness, sometimes spreading to the left shoulder, arm or jaw
- Settles within a few minutes of rest
Unstable angina happens at rest, is new, or is getting more frequent or severe. It is a medical emergency, just like a heart attack.
Common non-cardiac causes of shoulder pain
Most shoulder pain is not heart-related. Common causes include:
- Rotator cuff problems (tendinitis or tears): pain with overhead movements and at night. See rotator cuff tears: catching the symptoms early.
- Frozen shoulder: gradual stiffness and loss of movement, more common in people with diabetes.
- Shoulder impingement: pain when lifting the arm, common in gym-goers.
- Nerve pain from the neck: pain, tingling or numbness that travels down the arm.
- Muscle tension from stress and posture.
- Arthritis of the shoulder joint.
What tests confirm whether shoulder pain is from the heart?
If a heart cause is suspected, doctors may order:
- ECG (electrocardiogram): checks the heart’s electrical activity, usually done within minutes in an emergency
- Blood tests (troponin): detect heart muscle damage
- Echocardiogram: an ultrasound of the heart
- Stress test (TMT): checks for angina during exercise
- Coronary angiography: looks at blockages in the heart arteries
If heart causes are ruled out, a shoulder examination and imaging such as ultrasound or MRI can identify the musculoskeletal cause.
When should you see a doctor for shoulder pain (non-emergency)?
Book an appointment if:
- Shoulder pain has lasted more than 2 weeks or keeps returning
- Pain disturbs your sleep (in the meantime, these sleeping positions for shoulder pain may help)
- You cannot lift your arm or have lost strength
- The shoulder is stiff and movement is reducing
- Pain spreads down the arm with tingling or numbness
- You have risk factors for heart disease and new pain with exertion. See a doctor or cardiologist first to rule out a heart cause.
