What is chest pain?

There are numerous vital organs on the left side of the body. Under the left breastbone are the heart, spleen, stomach, pancreas, and large intestine. When you have chest pain on the left side above your breast, it can be caused by a variety of things. It is important to pay attention to other symptoms in addition to the pain to determine if you should seek medical attention. 

In some cases, pain in the chest may be angina which is a warning sign for heart disease. Angina happens because your heart muscle is not getting enough oxygen-rich blood. The pain feels like pressure or squeezing in your chest. The pain can spread from your left chest to your shoulders, neck, jaw, or back. This is similar to a heart attack

If you are experiencing prolonged chest pain on the left side, you should first rule out a heart attack before moving forward with treatment. Signs of a heart attack include: 

  • Chest pain 
  • Shortness of breath
  • Cold sweat, nausea, and lightheadedness
  • Discomfort, numbness, or pain in one or both arms, neck, stomach, jaw, or back
  • Squeezing sensation, fullness, or uncomfortable pressure in the center of your chest

Signs and symptoms of chest pain on the left side above a female breast

It can be difficult determining exactly where your pain is coming from. Especially chest pain, because the nerves in your chest do not always indicate the specific cause of the pain. It is important to determine if your chest pain is related to your heart. If it is not, there are other causes to consider. Chest pain on the left side can also be connected to other symptoms that might help you locate the cause. 

Related symptoms of chest pain on the left side above a female breast include: 

Pressure in the chest

Pressure in your chest on the left side can be an indicator of heart attack. It may feel like someone is sitting on your chest. However, this feeling can also be a symptom of angina which can indicate heart disease.

Radiating pain

Your pain can spread from your chest to your jaw, neck, shoulders, or back. It’s important to track where your pain started and where it spread. 


Feeling lightheaded can accompany chest pain on the left side. If you feel out of breath or dizzy, you should consult your doctor and tell them your symptoms.

Causes of chest pain on the left side above a female breast

Chest pain on the left side can have a variety of causes. After ruling out angina and heart attack, there are other causes you should look for. Those include: 


This is a frequent cause of chest pain. It’s related to indigestion and can feel like your heart is on fire. However, your heart is not affected by heartburn. It is actually your esophagus that burns from stomach acid coming up into your throat. 

Panic attack

A panic attack can have symptoms that mimic angina, and can cause your heart rate to increase, trembling, shortness of breath, dizziness, and chest pain. This is a psychiatric condition that needs to be treated by a mental health specialist.

Gallbladder disease

Gallstones and other gallbladder issues can cause pressure and extreme muscle spasms in your upper right stomach that can radiate to your chest, making you feel pain in your left chest. 

Peptic ulcer

These are sores that develop in your stomach due to acid from your digestive tract eating away your stomach, esophagus, or small interesting lining. Most often you will feel the pain in your stomach, but it can radiate to the middle or left of your chest. These sores are very painful and will require medication.


Because your lungs are located in your chest underneath your breasts, symptoms of pneumonia can cause pain in your left chest above your breast.

Diagnosing chest pain on the left side above a female breast

To diagnose the cause of your chest pain on the left side your doctor will discuss your symptoms and may run blood tests. They also may take X-rays or order an electrocardiogram (EKG) and exercise stress test. They will want to rule out a heart attack or other heart problems.

Once heart problems have been ruled out, they will look for other signs of trauma to your chest and breast and may run further tests to determine if it is related to another illness.
