Chest Pain

Heart & Circulation

If this is an emergency, call 911 now. This tool is for general information, not emergency guidance. If you're having severe symptoms, don't read this — get help.

What the internet says

Heart attack. Pulmonary embolism. Aortic dissection. Angina. Pericarditis. Possibly a rare parasitic infection.

What it probably actually is

Muscle strain from poor posture, acid reflux or heartburn, anxiety (very common — anxiety chest pain is real and physically uncomfortable), costochondritis (rib cartilage inflammation from coughing or exercise), or sleeping on your side awkwardly.

🧠 The full picture

The vast majority of chest pain in people under 65 without risk factors is musculoskeletal or GI-related. Heartburn alone accounts for a huge proportion of ER visits for "chest pain." Your chest has a lot of moving parts — ribs, cartilage, muscles, your esophagus running right through it. Most chest sensations are not your heart.

⚠️ When to actually call your doctor

These are real red flags. If any of these apply, don't wait.

Pain radiates to your left arm, jaw, or shoulder
Accompanied by shortness of breath, sweating, or nausea together
Crushing or pressure sensation (not sharp or stabbing)
Lasts more than 15 minutes without relief
You have a known heart condition or multiple risk factors (diabetes, high BP, smoking)
Pain came on suddenly at maximum intensity
