why does my chest hurt
Last updated September 6, 2026.
Most chest pain comes from the chest wall muscles and ribs, acid reflux, anxiety, or a lung infection, but pain from the heart is also possible, so pressure that lasts more than a few minutes needs emergency care. What changes the answer is the pattern. Pain that shows up with exertion and settles with rest, spreads to the arm, jaw, neck, or back, or comes with shortness of breath, sweating, or nausea points toward the heart and is an emergency. Burning behind the breastbone after meals or when you lie down usually points to reflux, while soreness that gets worse when you press on one spot, twist, or take a deep breath usually points to muscle or rib strain. Age, smoking, high blood pressure, diabetes, high cholesterol, and a family history of early heart disease all raise the chance that chest pain is cardiac. Keeping a short note of when the pain starts, how long it lasts, and what makes it better gives a clinician far more to work with than the pain alone.
What to do
- Treat sudden pressure as an emergency: Call 911 rather than driving yourself if chest pressure lasts more than a few minutes or comes with shortness of breath, sweating, or nausea.
- Time the episodes: Write down when the pain starts, how many minutes it lasts, and what you were doing, since duration and trigger separate most causes.
- Test the reflux pattern: If pain burns after large or late meals, try smaller meals, no food within three hours of bed, and raising the head of the bed.
- Check whether it is reproducible: Press on the sore spot or twist your torso; pain that you can bring on by touch or movement usually comes from the chest wall.
- Know your risk numbers: Have your blood pressure, cholesterol, and blood sugar checked, because those results change how chest pain should be worked up.
- Book a visit for repeat episodes: See a clinician for pain that returns with activity, wakes you at night, or is new for you, even if each episode passes quickly.
