Knowing About Chest Pain During Exercise

Feeling pain in your chest when you are working out can be scary. Many people feel this. It is known as chest pain during exercise. This pain can happen while you are active or right after you stop. For example, some people get chest pain after running.

There are many reasons why this happens. Some reasons are not very serious. Some reasons are quite serious and need medical help fast.

Let’s look at what might be causing this pain.

Simple Reasons for Chest Pain During Exercise

Sometimes, chest pain during exercise is not linked to your heart at all. It can come from other parts of your body near your chest.

Muscle Pain and Strain

Your chest area has many muscles. You use these muscles when you exercise. You use them to move your arms, lift weights, or even just swing your arms when running.

Doing new exercises or pushing yourself too hard can strain these muscles. A muscle strain means you have stretched or slightly torn a muscle. This can feel like pain or soreness in your chest wall. This is called muscle strain chest wall exercise.

What it feels like: Usually a sore, aching pain. It might hurt more when you move certain ways or press on the sore spot. It usually gets worse after exercise, not during.
Why it happens with exercise: Muscles work hard when you exercise. If they are not used to it, or you use them too much, they can get hurt.
How to know: Does the pain feel like it’s right on the surface? Does it hurt when you press there? Did you do a new workout or lift something heavy? These can point to a muscle problem.

Pain Where Ribs Meet Breastbone

Your ribs connect to a bone in the middle of your chest called the breastbone. There is a soft area called cartilage where they join. This area can become sore and cause pain. This is called costochondritis.

Exercise can make costochondritis worse. Deep breaths taken during exercise can also make it hurt more.

What it feels like: Sharp, stabbing pain. It usually hurts in a specific spot or spots along the edge of your breastbone. Pressing on these spots makes the pain worse. It can feel scary because it’s in the chest area.
Why it happens with exercise: Moving your arms and chest a lot during exercise can pull on the sore cartilage. Deep breathing also makes the ribs move, which can cause pain.
How to know: Does the pain get worse when you press on the bones where your ribs meet your breastbone? Does it hurt more when you twist your body or take a very deep breath? If yes, it might be costochondritis.

Breathing Tube Problems

Some people have breathing problems that show up when they exercise. A common one is exercise-induced asthma. Asthma makes your breathing tubes (airways) get narrow. When you exercise, you breathe harder and faster. This can make the airways tighten up.

When this happens, you might feel chest tightness. It can be hard to breathe, and you might cough or wheeze (make a whistling sound when breathing). This is often linked with shortness of breath and chest tightness exercise.

What it feels like: Tightness or squeezing in the chest. You feel like you can’t get enough air. You might cough a lot or wheeze. These signs usually start a few minutes into exercise or right after you finish.
Why it happens with exercise: The air you breathe during exercise can be drier or colder than usual. Breathing fast can also dry out the airways. This makes them squeeze shut in people with sensitive airways.
How to know: Have you had asthma before? Do you cough, wheeze, or feel very breathless when you run or exercise hard? Do these signs go away if you rest or use an asthma inhaler? If yes, it might be exercise-induced asthma.

Stomach Problems

Sometimes, chest pain is caused by problems in your stomach or food pipe (esophagus). If stomach acid comes back up into your food pipe, it can cause a burning feeling in your chest. This is called heartburn or acid reflux.

Exercise can sometimes make heartburn worse. Jumping or bending over can cause acid to come up. Eating right before exercise can also be a problem.

What it feels like: A burning feeling behind your breastbone. It might come with a sour taste in your mouth. It’s usually felt higher up in the chest.
Why it happens with exercise: Physical activity can put pressure on your stomach. This can push acid up into your food pipe.
How to know: Does the pain feel like burning? Does it happen after you eat and then exercise? Do you sometimes taste acid in your mouth? Does taking an antacid medicine help? If yes, it might be heartburn.

Here is a simple look at some less serious causes:

Cause	What it Might Feel Like	When it Might Happen	Other Signs
Muscle Strain Chest Wall	Sore, aching pain; hurts to touch spot	Usually after exercise, or with certain moves	Pain when pressing on the muscle area
Costochondritis	Sharp, stabbing pain; in specific spot	With movement, deep breaths	Pain when pressing where ribs meet breastbone
Exercise-Induced Asthma	Tightness, squeezing; hard to breathe	During or right after exercise	Coughing, wheezing, shortness of breath
Heartburn (Acid Reflux)	Burning feeling; higher up chest	After eating, with certain movements	Sour taste in mouth, bloating

It is easy to mix up these pains with more serious issues. That’s why it is always best to be careful.

More Serious Reasons for Chest Pain During Exercise

Sometimes, chest pain during exercise is a sign that your heart is not getting enough blood. This is a serious issue. Your heart is a muscle that needs a lot of blood to work hard when you exercise. If the pipes that carry blood to your heart (coronary arteries) are narrow or blocked, your heart muscle doesn’t get enough oxygen.

This lack of oxygen to the heart muscle causes chest pain. This kind of pain is called angina. When it happens because you are exercising, it is called angina pectoris exercise.

Angina Pectoris

Angina is a warning sign. It means your heart is working hard but not getting the blood it needs. This usually happens when you make your heart work harder, like when you exercise, run, or walk fast uphill.

What it feels like: Often feels like pressure, squeezing, fullness, or pain in the center of your chest. It can also feel like tightness or a heavy weight. The pain can spread to your arm (often the left), neck, jaw, back, or stomach.
Why it happens with exercise: Exercise makes your heart beat faster and pump more blood. If the blood pipes are narrow, they can’t deliver enough blood to meet the heart’s higher need for oxygen.
How to know: Does the pain start when you begin exercising and get worse as you work harder? Does the pain go away a few minutes after you stop exercising and rest? Does it happen again almost every time you do the same amount of exercise? If yes, it might be angina. Angina that happens only with activity and goes away with rest is called “stable angina.”

Heart Attack Symptoms During Exercise

A heart attack is a very serious medical emergency. It happens when blood flow to a part of the heart muscle is blocked completely or almost completely. This causes damage to the heart muscle.

Sometimes, the heart attack symptoms exercise can feel like angina, but they are usually worse and do not go away with rest. Exercise can sometimes trigger a heart attack, especially if you have blocked arteries and don’t know it.

What it feels like: Severe pressure, squeezing, fullness, or pain in the chest. It can feel like someone is sitting on your chest. The pain can spread to the arm, neck, jaw, back, or stomach. You might also feel very sick to your stomach, cold sweats, feel dizzy, or have extreme shortness of breath.
Why it might happen with exercise: If an artery is already very blocked or a clot forms, the extra stress of exercise can cut off blood flow completely.
How to know: Does the chest pain feel very bad and not go away after you stop exercising? Does it come with other signs like cold sweat, feeling sick, or really bad shortness of breath? If you think you might be having a heart attack, call emergency services right away. Do not wait.

Cause	What it Might Feel Like	When it Might Happen	Other Signs
Angina Pectoris Exercise	Pressure, squeezing, heavy feeling; spreads to arm/jaw	Starts with exercise, ends with rest	Goes away after a few minutes of rest, happens often with same effort
Heart Attack	Severe pressure, squeezing; doesn’t stop with rest	Can happen during or after exercise	Cold sweat, feeling sick, dizziness, bad shortness of breath
Heart Valve/Muscle Problems	Pain, tiredness, shortness of breath	During exercise, gets worse with effort	Swelling in legs, feeling very tired, hard to breathe even at rest in severe cases

Figuring Out the Signs: When is Chest Pain Serious?

It can be hard to tell the difference between muscle pain, heartburn, or a heart problem. But there are signs that mean you should take the pain very seriously.

Red Flag Signs (See a Doctor Fast or Call Emergency Services):

Pain that feels like pressure, squeezing, or tightness in your chest. This is a classic sign of a heart issue.
Pain that spreads to your arm (especially the left), shoulder, neck, jaw, back, or stomach.
Chest pain that does not go away after you stop exercising and rest for 5-10 minutes.
Chest pain that comes with other bad signs like cold sweat, feeling very sick to your stomach, feeling dizzy or lightheaded, or extreme shortness of breath and chest tightness exercise.
Pain that is very strong or suddenly gets much worse.
Chest pain that happens with less and less exercise (e.g., first it happened when you ran fast, now it happens when you walk slowly). This is called unstable angina and is very serious.
If you have known heart problems and your chest pain feels different or worse than your usual angina.

Signs That Might Be Less Serious (But Still See a Doctor Soon):

Pain that gets worse when you push on a spot on your chest or ribs.
Pain that changes when you move your arms or twist your body (can be muscle or joint related).
Burning pain, especially if it happens after eating and is linked to a sour taste (likely heartburn).
Pain that comes with coughing, wheezing, or feels like you can’t breathe well, especially if you have a history of asthma.
Pain that only lasts a few seconds at a time. (Heart pain often lasts several minutes).

Remember, any new chest pain when you exercise should be checked out by a doctor. It is better to be safe than sorry. Causes of chest pain during exercise need proper medical review.

Getting Checked by a Doctor

When you see a doctor about chest pain during exercise, they will ask you many questions.

What does the pain feel like? (Is it sharp, dull, heavy, squeezing?)
Where exactly is the pain? Does it move anywhere?
When did it start?
Does it happen every time you exercise? With what kind of exercise? How hard do you have to work?
Does it stop when you rest? How quickly?
Do you have other signs like shortness of breath, feeling sick, or dizziness?
Do you have any health problems already, like high blood pressure, high cholesterol, diabetes, or a family history of heart problems?

They will also give you a physical check-up.

The doctor might order tests to find out the cause.

ECG (Electrocardiogram): This test records your heart’s electrical activity. It can show if your heart is getting enough oxygen or if you’ve had a heart attack.
Stress Test: This is often done to see how your heart works when you exercise. You will walk on a treadmill or ride a bike while hooked up to an ECG. This test is very helpful to see if you have angina pectoris exercise.
Echocardiogram: This test uses sound waves to make pictures of your heart. It shows the size, shape, and how well your heart muscle and valves are working.
Chest X-ray: This picture of your chest can show problems with your lungs or the shape of your heart.
Blood Tests: These can check for signs of heart damage or other problems.
Cardiac CT or MRI: These are more detailed pictures of your heart and blood vessels.
Cardiac Catheterization (Angiogram): This is a more involved test where a thin tube is put into a blood vessel and guided to your heart. A special dye is used to show if your coronary arteries are blocked.

Finding the cause of your chest pain is important so you can get the right treatment.
