Shoulder pain is a widespread issue, often due to injury or overuse. While usually benign, it can sometimes signal a more serious underlying health concern, including heart problems. Understanding the differences between common shoulder ailments and potential cardiac issues is important for knowing when to seek medical attention.
The Connection Between Heart and Shoulder Pain
Pain originating from the heart can manifest in the shoulder due to a phenomenon known as referred pain. This occurs because the heart and the shoulder share nerve pathways that connect to the same segments of the spinal cord. When the heart experiences an issue, such as reduced blood flow, the brain may interpret these signals as originating from another area along the shared nerve pathway, such as the shoulder.
This neurological crossover means heart problems, like a heart attack or angina, can project pain to areas distant from the heart itself. The brain’s interpretation can lead to pain being felt in the shoulder, arm, neck, or jaw, even though the problem lies with the heart. This explains why left shoulder pain can sometimes be a warning sign of a heart-related condition.
Identifying Heart-Related Shoulder Pain
Heart-related shoulder pain has distinct characteristics. It often affects the left shoulder but can also involve the right, both shoulders, or radiate to the chest, jaw, neck, back, or arms. This pain is typically described as a pressure, squeezing, fullness, dull ache, or burning sensation, rather than sharp or stabbing.
Associated symptoms often accompany this pain, including nausea, sweating, shortness of breath, lightheadedness, and unusual fatigue. The pain may also be triggered or intensified by physical exertion, emotional stress, or cold weather. Unlike typical muscle pain, cardiac-related shoulder pain may not be relieved by rest or changing position. It can persist for more than a few minutes, and its intensity might fluctuate.
Other Common Causes of Shoulder Pain
Shoulder pain not related to the heart usually stems from musculoskeletal issues. Common causes include strains or sprains, injuries to muscles, tendons, or ligaments. Arthritis, such as osteoarthritis or rheumatoid arthritis, can also cause shoulder pain due to inflammation and joint degeneration. These conditions often lead to pain localized in the shoulder joint or surrounding tissues.
Rotator cuff issues, including tendinitis or tears, are frequent culprits. Bursitis, an inflammation of fluid-filled sacs that cushion joints, can also cause pain and tenderness. Pinched nerves in the neck or shoulder can result in radiating pain, numbness, or tingling down the arm. Pain from these non-cardiac causes typically worsens with specific movements, improves with rest, and often responds to localized treatments.
When to Seek Urgent Medical Care
Immediate medical attention is necessary if shoulder pain is sudden and severe, especially without a clear injury. Call emergency services if it’s accompanied by shortness of breath, sweating, nausea, dizziness, or chest discomfort. Pain radiating to the jaw, neck, back, or down one or both arms also warrants urgent evaluation.
Any shoulder pain that doesn’t subside after a few minutes of rest, or if there’s a history of heart disease or significant cardiac risk factors, should be promptly assessed. Avoid driving yourself to the hospital; wait for emergency personnel. When in doubt, seeking emergency medical care is the safest approach to rule out a heart-related issue.

Identifying Heart-Related Shoulder Pain
Heart-related shoulder pain has distinct characteristics. It often affects the left shoulder but can also involve the right, both shoulders, or radiate to the chest, jaw, neck, back, or arms. This pain is often described as a heavy or squeezing sensation, dull ache, pressure, fullness, or burning, rather than sharp or localized discomfort.
Associated symptoms frequently accompany this pain, including shortness of breath, nausea, sweating, lightheadedness, unusual fatigue, indigestion, or chest tightness. These symptoms often occur alongside the shoulder pain, making it distinct from isolated musculoskeletal discomfort.
Cardiac-related shoulder pain can be triggered by physical exertion, emotional stress, or cold weather. Unlike typical muscle pain, it may not be relieved by rest or changing position. It can persist for more than a few minutes, and its intensity might fluctuate. The presence of these symptoms together should prompt concern.
Other Common Causes of Shoulder Pain
Shoulder pain not related to the heart usually stems from musculoskeletal issues, often localized to the shoulder joint or surrounding tissues. Musculoskeletal injuries like strains or sprains from overuse or trauma are common culprits. This pain often presents as soreness or tenderness, worsening with specific movements.
Arthritis, including osteoarthritis and rheumatoid arthritis, can cause persistent pain due to inflammation and joint degeneration. This pain typically involves stiffness, reduced range of motion, and may be worse in the morning or after inactivity. Rotator cuff issues, such as tendinitis or tears, lead to pain when lifting the arm or performing overhead activities.
Bursitis, an inflammation of the fluid-filled sacs cushioning the shoulder joint, can cause localized pain and tenderness, often exacerbated by pressure or movement. Pinched nerves from the neck can also cause radiating pain, numbness, or tingling down the arm. These non-cardiac pains usually respond to rest, ice, and specific physical movements, and rarely present with systemic symptoms associated with heart problems.
When to Seek Urgent Medical Care
Immediate medical attention is necessary if shoulder pain is sudden and severe, especially without a clear injury. Call emergency services, such as 911, if it’s accompanied by shortness of breath, excessive sweating, nausea, dizziness, or chest discomfort. Pain radiating to the jaw, neck, back, or down one or both arms also warrants urgent evaluation.
Any shoulder pain that doesn’t subside after a few minutes of rest, or if there’s a history of heart disease or significant cardiac risk factors like high blood pressure, high cholesterol, and diabetes, requires prompt medical assessment. Avoid driving yourself to the hospital; wait for emergency personnel. When in doubt, seeking emergency medical care is the safest approach to rule out a heart-related issue.
