In this blog, we’ll break down the potential causes of chest pain and help you determine when it might signal something serious.

Common Causes of Chest Pain

Chest pain can arise from various organs and systems in the body, including the heart, lungs, esophagus, muscles, and even the digestive system. Here are some of the most common sources:

1. Cardiac-Related Chest Pain

Heart-related causes are often the most concerning. These include:

• Heart attack (myocardial infarction): Caused by a blockage in blood flow to the heart muscle. Pain may feel like pressure, squeezing, or a heavy weight on the chest and may radiate to the arm, jaw, or back.

• Angina: Chest discomfort due to reduced blood flow to the heart. Often triggered by physical exertion or stress and relieved by rest.

• Pericarditis: Inflammation of the sac around the heart, often causing sharp pain that worsens with deep breathing or lying down.

2. Gastrointestinal Causes

Not all chest pain is heart-related. Digestive issues are a common culprit:

• Heartburn or acid reflux: A burning sensation in the chest caused by stomach acid moving up the esophagus.

• Esophageal spasm: Sudden, painful contractions of the esophagus.

• Gallbladder issues: Pain from gallstones can radiate to the chest and mimic cardiac pain.

3. Musculoskeletal Pain

Chest pain can also originate from the muscles or bones:

• Muscle strain: Often due to heavy lifting, exercise, or injury.

• Costochondritis: Inflammation of the cartilage where the ribs attach to the breastbone, causing sharp pain that worsens with movement or pressure.

4. Pulmonary Causes

Lung-related conditions may also present as chest pain:

• Pulmonary embolism: A blood clot in the lungs that causes sudden, sharp chest pain and difficulty breathing.

• Pneumonia: Infection of the lungs that can cause pain with deep breaths.

• Pleuritis (pleurisy): Inflammation of the lining around the lungs.

5. Anxiety and Panic Attacks

Emotional stress can lead to physical symptoms. Panic attacks often cause chest tightness, rapid heartbeat, and shortness of breath—symptoms that can mimic a heart attack but are not life-threatening.

When to Seek Immediate Medical Attention

While many causes of chest pain are harmless, some require urgent care. Seek emergency medical attention if you experience:

• Pressure, squeezing, or tightness in the chest

• Pain radiating to the arm, neck, jaw, or back

• Shortness of breath

• Nausea or vomiting

• Dizziness or lightheadedness

• Sweating or cold sweats

• Irregular heartbeat or palpitations

Don’t try to self-diagnose. If you’re unsure, it’s always safer to get checked out by a medical professional.

How Chest Pain Is Diagnosed

Doctors use a combination of tools and tests to determine the cause of chest pain:

• Electrocardiogram (ECG/EKG) to assess heart rhythm

• Blood tests to detect heart damage (e.g., troponin levels)

• Chest X-rays or CT scans to evaluate the lungs and heart

• Stress tests to observe heart function during exertion

• Endoscopy to examine the esophagus in gastrointestinal cases

A thorough medical history and physical exam will also help guide diagnosis and treatment.

Takeaway: Don’t Ignore Chest Pain

Chest pain should never be dismissed—especially if it comes on suddenly, worsens over time, or is accompanied by other symptoms. While it’s true that not all chest pain is life-threatening, it’s better to be safe than sorry. Prompt evaluation can save your life if a serious condition like a heart attack or pulmonary embolism is the cause.

If you or someone you know is experiencing unexplained chest pain, call emergency services or go to the nearest hospital immediately.
