Jaw, arm pain or «heartburn» with effort: could it be the heart?

Reviewed by Dr. Rebeca Granada, cardiologist · RP 17.697 · 13/10/2026

What many people think

It is often mistaken for digestive, dental or muscle problems.

Why it may be related to the heart

Pain that comes with effort and eases with rest may come from the heart, even if it is not in the chest. It is more common in women, older adults and people with diabetes. If it is intense or does not go away, it is an emergency.

When to see a cardiologist

If the pain or «heartburn» appears when walking, climbing stairs or with strong emotions, and eases when you rest.

Tests usually ordered

  • Electrocardiogram (ECG)
  • Exercise stress test
  • Echocardiogram

Frequently asked questions

Why can heart pain be felt in the jaw?

Because heart nerves share pathways with other areas, so the pain can be felt in the jaw, arm or back.
