We all know that running is good for the heart and lungs. Within just the first minute or so of any run, you can start to feel your pulse increasing as your heart beats faster to pump enough oxygenated blood to your working muscles. 

Some runners notice mild chest tightness or heaviness when they first head out for their run, but feeling chest pain when running can be quite concerning. It’s normal to immediately worry that any amount of or type of chest pain when running or chest pain after workouts is indicative of a potentially fatal heart attack.

Fortunately, there are several less severe or alarming causes of chest pain when running. However, it’s important to know the signs and symptoms of various causes of chest pain when running to ensure you catch anything concerning before it becomes serious. If you are asking yourself, why does my chest hurt after running, or while running, keep on reading.

In this guide, we will discuss the common causes of chest pain when running and what to do about it.

Why Does My Chest Hurt When I Run?

There are quite a few potential causes of chest pain when running, ranging in severity from mild or benign to life-threatening. 

Given the potential seriousness of chest pain during exercise, it’s imperative that you seek immediate medical attention or speak to your doctor as soon as possible if you have concerns about chest pain during your workout or experience lingering chest pain after workouts.

It’s important to be aware of the signs and symptoms of a heart attack so that you can differentiate less concerning causes of chest pain during exercise from this life-threatening situation.

Signs and Symptoms of a Heart Attack

A heart attack also called a myocardial infarction, occurs when part of the heart muscle is deprived of oxygen because of a blockage in one of the coronary arteries that feed the heart.

Deprivation of oxygen to the heart tissue referred to as ischemia can cause the heart muscle to die. 

Depending on the location and extent of the ischemia, the heart attack can be fatal because the damaged heart muscle is either no longer able to conduct the electrical signal to contract or has too much dead muscle tissue to be able to adequately contract and pump blood through the body. 

There are early symptoms of a heart attack that may occur in 50 percent of all people who have heart attacks, according to the Society of Cardiovascular Patient Care.

Being cognizant of the early signs of a heart attack can help you recognize the condition before significant damage is done.

Early signs of a heart attack can include any or all of the following:

  • “Stuttering” chest pain, which is essentially mild chest pain or discomfort that comes on, then dissipates, one or multiple times
  • Sweating
  • Shoulder, neck, or jaw pain 
  • Feeling faint or dizzy
  • Breathlessness 
  • Nausea or vomiting 
  • Anxiety, confusion, or fear 

Symptoms of a heart attack once it’s past the early stages tend to vary based on your sex.

Men tend to display the more “classic” symptoms, such as chest pain, pressure, tightness, or discomfort, often described as a “piano fell on your chest”; rapid or irregular heartbeat; breathlessness, left arm pain; a feeling of indigestion; lightheadedness; and breaking out in a cold sweat. 

Women, on the other hand, might feel chest pain and some of these classic symptoms, or they might also experience extreme fatigue, nausea, jaw pain, upper back pain radiating down the arm or to the chest or abdomen, flu-like symptoms, indigestion, anxiety, dizziness, and throat pain.

When to Be Concerned About Chest Pain When Running

Knowing the signs and symptoms of a heart attack can help you know when your chest pain when running is potentially indicative of this severe condition.

Therefore, if you are experiencing any of the following signs and symptoms alongside your chest pain during or after running, call 911 immediately:

  • A squeezing pressure in the chest, acute chest pain, or uncomfortable fullness in the chest
  • Abnormal or inconsistent heart rhythm or rate 
  • Shortness of breath 
  • Dizziness
  • Excessive sweating 
  • Nausea 

Additionally, if you have other risk factors for heart disease or cardiovascular disease, you should speak with your healthcare provider about any chest pain you feel during or after exercise.

Chest Pain When Running? Here Are 8 Potential Causes

Now that we have the life-threatening concerns out of the way, let’s address other potential causes of chest pain when running.

#1: Angina Pectoris

Angina pectoris, typically referred to as just angina, is a common cause of chest pain while exercising. Angina is due to a lack of blood flow to the heart, resulting in tightness, pressure, or chest pain, particularly during physical exertion.

Unlike a heart attack, angina pain typically alleviates when you stop exercising, so if you still have chest pain after running, it’s more concerning.

#2: Asthma

Asthma is a condition marked by inflammation of the airway, which can cause breathlessness, pressure, coughing, and chest pain when running. Exercise is often a trigger for bronchoconstriction with asthma.

#3: Muscle Strains

We often don’t think about the muscles involved in breathing, but it’s fairly common to strain intercostal muscles in the chest. Intercostal strains or injuries can cause chest pain while breathing because the expansion of the chest stretches the muscle fibers.

#4: Heartburn

Heartburn, GERD, or indigestion can also cause chest pain when running, particularly if you run after eating. Fried or fatty foods, caffeinated foods and drinks, and spicy foods are especially irritating to the stomach and can cause symptoms of burning and pain in the chest or abdomen.

#5: Pleurisy

Running outside in the cold or in poor air quality can cause a condition called pleurisy, which is an inflammation of the tissues lining the lungs and chest. 

Runners with asthma or who have had a recent respiratory infection are at a greater risk of pleurisy if they run outside. Symptoms can include chest pain when running, a painful cough, and difficulty breathing.

#6: Dehydration and Cramping

The intercostal muscles between the ribs can cramp up, particularly if you are dehydrated or have an electrolyte imbalance.

#7: Costochondritis

Costochondritis is an inflammation of the cartilage by the breastbone. It is more common among women and generally resolves on its own. It can cause chest pain with physical exertion and can be caused by repetitive, high-impact activities like running.

#8: COVID-19

The coronavirus can cause chest pain, tightness, and breathlessness when running even if you have minimal symptoms at rest.

What to Do About Chest Pain When Running

Given the range of potential causes of chest pain when running, it’s difficult to give advice on what to do to alleviate the problem. However, here are some tips that may be helpful, depending on your situation:

  • Consult your healthcare provider or cardiologist
  • Examine your hydration strategy 
  • Wait longer after eating before running if you deal with heartburn, and cut back on trigger foods
  • Take an inhaler if you have asthma or consider getting a consult if you think you might
  • Rest if you have a muscle strain, pleurisy, costochondritis, or COVID-19
  • Warm-up instead of jumping into your workout

Remember, if you have any concerns about the health of your heart or a potential heart attack, seek emergency medical care. It’s always better to err on the side of caution. Your doctor can get to the root of your specific case and answer your questions such as: why does my chest hurt after running, or while running with great certainty.

As runners, there are many discomforts that we can experience throughout our running careers, but there do exist ways in which we can treat, and hopefully even prevent them from occurring in the first place.
