Chest Pain: Possible Causes, Red Flags & When to Seek Care

Chest pain is a critical medical symptom that should always be evaluated with caution. It refers to pain, pressure, or discomfort felt anywhere in the chest area, from your shoulders down to the upper abdomen. Chest pain has many possible causes, ranging from harmless issues like muscle strains or indigestion to life-threatening conditions like a heart attack or pulmonary embolism. Because it can be difficult to distinguish between cardiac and non-cardiac chest pain based on symptoms alone, understanding the warning signs of a medical emergency is paramount for your safety.

Quick Summary Box

Possible Causes Include

Chest wall muscle strain, Acid reflux (GERD), Angina (Cardiac pressure)

Warning Signs (Red Flags)

Sudden severity, chest pressure, difficulty breathing, confusion, or weakness.

When to Seek Care

Seek urgent care for emergency signs. Consult primary care if symptoms persist beyond a few days.

What to Track

Record onset, triggers, pain levels (1-10), and response to self-care or medications.

What chest pain may feel like

Chest pain can take many forms. It may feel like a crushing pressure, squeezing tightness, or a heavy weight sitting on your chest. It can present as a sharp, stabbing pain that worsens when you take a deep breath or cough. You might experience a burning sensation in your chest or upper stomach, similar to heartburn. The pain may be highly localized to a specific spot that feels tender when pressed, or it may radiate widely to your left arm, shoulder, neck, jaw, or back.

Common possible causes of chest pain

The following are common reasons someone might experience this symptom. This list is for educational context only and does not represent a diagnosis. A proper clinical assessment is required to identify the root cause.

Chest wall muscle strain

Inflammation or strain of the muscles and ligaments in the chest wall, often caused by heavy lifting, poor posture, intense upper-body workouts, or persistent coughing.

Why it may fit: Fits if the chest pain is localized, feels sore or tender when you press on the chest bone or ribs, and changes in intensity when you twist or move your upper body.

When to seek care: Manage with rest, gentle stretching, and warm compresses. Consult a primary care clinician if the pain persists, worsens, or is accompanied by chest tightness or breathing difficulty.

Acid reflux (GERD)

Stomach acid escaping up into the esophagus irritates the sensitive lining, causing a painful burning sensation in the chest behind the breastbone.

Why it may fit: Fits if the discomfort is a burning chest sensation that occurs after eating, is worse when lying flat or bending over, and is accompanied by a sour taste in the mouth.

When to seek care: Consult a healthcare provider if acid reflux is frequent, severe, or mimics chest pressure. Seek emergency care if you are unsure whether the pain is cardiac or gastrointestinal.

Angina (Cardiac pressure)

Angina is chest pain or discomfort that occurs when a part of the heart muscle does not receive enough oxygen-rich blood, typically due to narrowed coronary arteries during physical exertion or stress.

Why it may fit: Fits if the discomfort feels like a squeezing pressure, tightness, or fullness in the center of the chest that is triggered by exercise or stress and resolves within minutes of resting.

When to seek care: Consult a cardiologist or primary care clinician today for diagnostic testing. Angina is a sign of underlying cardiovascular disease.

Red flags: when to seek urgent care

Urgent Medical Attention Required

Certain symptoms can indicate a serious or life-threatening condition that requires immediate medical evaluation. Seek emergency care (call 911 or visit the nearest ER) if you experience chest pain alongside any of the following signs:

⚠ Crushing chest pain, pressure, squeezing, or heaviness in the center of the chest
⚠ Chest pain that radiates to your left arm, shoulder, neck, jaw, or back
⚠ Chest pain accompanied by sudden shortness of breath or difficulty breathing
⚠ Chest pain with cold sweating, dizziness, lightheadedness, or nausea
⚠ Chest pain that began suddenly and continues to worsen at rest
⚠ Chest pain accompanied by an irregular or racing heartbeat

What to track before seeing a doctor

To help your healthcare provider make a more accurate diagnosis, it is highly recommended to monitor and record detailed information about your symptom. Use this checklist as a guide:

✓ Note the exact time the chest pain started and how long it lasted.
✓ Describe the pain characteristics (e.g., crushing pressure, sharp stabbing, burning, tender to the touch).
✓ Track what activities, movements, or positions make the chest pain better or worse.
✓ Note any accompanying symptoms such as sweating, dizziness, nausea, or shortness of breath.

Questions a doctor may ask you

During a clinical examination, a doctor or healthcare provider will ask detailed questions to narrow down the possible causes. Being prepared for these questions helps ensure a productive consultation:

? Does the pain feel like a heavy weight, squeezing pressure, or tightness in your chest?
? Does the discomfort travel to your arm, shoulder, neck, jaw, or back?
? Does the pain change when you take a deep breath, press on your chest, or move your body?

Frequently asked questions about chest pain

Heartburn typically causes a burning chest pain that stays in the chest/throat, worsens when lying down, and is relieved by antacids. A heart attack usually presents as a heavy squeezing pressure or tightness, often radiating to the arm, neck, or jaw, accompanied by shortness of breath, cold sweating, nausea, or dizziness. However, symptoms can overlap, so any new, severe, or suspicious chest pain warrants immediate medical evaluation.

Costochondritis is the inflammation of the cartilage that connects your ribs to your breastbone. It causes a sharp chest pain that is characteristically tender to the touch and worsens when taking a deep breath or coughing, but it is not linked to cardiovascular issues.

The nerves that supply the heart and the nerves that supply the left arm send sensory signals to the same area of the spinal cord and brain. When the heart muscle is oxygen-deprived, the brain can misinterpret the signals, perceiving the pain as originating from the left arm or shoulder. This is known as referred pain.
