Chest pain is a very common complaint. Pain may be sharp or dull, although some people with a chest disorder describe their sensation as discomfort, tightness, pressure, gas, burning, or aching. Sometimes people also have pain in the back, neck, jaw, upper part of the abdomen, or arm. Other symptoms, such as nausea, cough, or difficulty breathing, may be present depending on the cause of the chest pain.
Many people are well aware that chest pain is a warning of potential life-threatening disorders and seek evaluation for minimal symptoms. Other people, including many with serious disease, minimize or ignore its warnings.
Causes of Chest Pain
Many disorders cause chest pain or discomfort. Not all of these disorders involve the heart. Chest pain may also be caused by disorders of the digestive system, lungs, muscles, nerves, or bones.
Overall, the most common causes of chest pain are
Disorders of the ribs, rib cartilage, chest muscles (musculoskeletal chest wall pain), or nerves in the chest
Inflammation of the membrane that covers the heart (pericarditis Overview of Pericardial Disease Pericardial disease affects the pericardium, which is the flexible two-layered sac that envelops the heart.

This limited blood flow causes chest pain when people exert themselves.
Some causes of chest pain are immediately life threatening but, except for heart attack or unstable angina, are less common:
Heart attack or unstable angina
A type of collapsed lung in which pressure builds up enough to obstruct blood flow returning to the heart (tension pneumothorax Tension Pneumothorax Tension pneumothorax occurs when air accumulates between the chest wall and the lung and increases pressure in the chest, reducing the amount of blood returned to the heart. Symptoms include... read more )
Other causes range from serious, potential threats to disorders that are simply uncomfortable.
Evaluation of Chest Pain
People with chest pain should be evaluated by a doctor. The following information can help people decide when evaluation is needed and help them know what to expect during the evaluation.
In people with chest pain or discomfort, certain symptoms and characteristics are cause for concern. They include
Crushing or squeezing pain
Shortness of breath
Nausea or vomiting
Pain in the back, neck, jaw, upper abdomen, or one of the shoulders or arms
Light-headedness or fainting
Sensation of rapid or irregular heartbeat
When to see a doctor
Although not all causes of chest pain are serious, because some causes are life threatening, the following people should see a doctor right away:
Those with new chest pain (within several days)
Those who have a warning sign
Those who suspect that a heart attack is occurring (for example, because symptoms resemble a previous heart attack)
These people should call emergency services (911) or be taken to an emergency department as quickly as possible. People should not try to drive themselves to the hospital.
Chest pain that lasts for seconds (less than 30 seconds) is rarely caused by a heart disorder. People with very brief chest pain need to see a doctor, but emergency services are usually not needed.
People who have had chest pain for a longer time (a week or more) should see a outpatient doctor as soon as possible unless they develop warning signs or the pain has steadily been getting worse or coming more often, in which case they should go to the hospital right away.
What the doctor does
Doctors first ask questions about the person's symptoms and medical history and then do a physical examination. What they find during the history and physical examination often suggests a cause of the chest pain and the tests that may need to be done.
However, symptoms due to dangerous and not dangerous chest disorders overlap and vary greatly. For example, although a typical heart attack causes dull, crushing chest pain, some people with a heart attack have only mild chest discomfort or complain only of indigestion or arm or shoulder pain (referred pain—see Figure: What Is Referred Pain? What Is Referred Pain? ). On the other hand, people with indigestion may simply have an upset stomach, and those with shoulder pain may have only sore muscles. Similarly, although the chest is tender when touched in people with musculoskeletal chest wall pain, the chest can also be tender in people who are having a heart attack. Thus, doctors usually do tests on people with chest pain.
For adults with sudden chest pain, tests are done to rule out dangerous causes. For most people, initial tests include
Measurement of oxygen levels with a sensor placed on a finger (pulse oximetry)
If symptoms suggest an acute coronary syndrome or if no other cause is clear (particularly in people who are at high risk), doctors usually measure levels of substances that indicate heart damage (cardiac markers) in the blood (at least two separate times over a few hours) and do repeated ECGs Electrocardiography Electrocardiography (ECG) is a quick, simple, painless procedure in which the heart’s electrical impulses are amplified and recorded. This record, the electrocardiogram (also known as an ECG)... read more .

However, if a newer cardiac marker, called high sensitivity troponin, is used and that test does not show evidence of heart damage, further testing may not be required. For a stress test, ECG or an imaging test (such as echocardiography Echocardiography and Other Ultrasound Procedures Ultrasonography uses high-frequency (ultrasound) waves bounced off internal structures to produce a moving image. It uses no x-rays. Ultrasonography of the heart (echocardiography) is one of... read more ) is done during exercise (often on a treadmill) or after a drug is given to make the heart beat fast or increase blood flow through the coronary arteries (such as dipyridamole).
If pulmonary embolism is suspected, computed tomography (CT) of the lungs or a lung scan Chest Imaging Chest imaging studies include X-rays Computed tomography (CT) CT angiography Magnetic resonance imaging (MRI) read more is done. If pulmonary embolism is considered only somewhat possible, a blood test to detect clots (D-dimer test) is often done. If this test is negative, pulmonary embolism is unlikely, but if the test is positive, other tests, such as ultrasonography of the legs or CT of the chest, are often done.
In people who have had chest pain for a long time, immediate threats to life are unlikely. Most doctors initially do only a chest x-ray and then do other tests based on the person's symptoms and examination findings.
Treatment of Chest Pain
Specific identified disorders are treated. If the cause is not clearly benign, people are usually admitted to the hospital or an observation unit for heart monitoring and more extensive evaluation. Symptoms are treated with acetaminophen or opioids as needed until a diagnosis is made.
Key Points about Chest Pain
Chest pain may be caused by serious life-threatening disorders, so people with new chest pain (within a few days) should get immediate medical attention.
The symptoms of life-threatening and non–life-threatening disorders overlap, so testing is usually needed to determine a cause.
