Chest Pain: Causes, Red Flags, and When to Seek Help
When you feel chest pain, a discomfort or pressure in the chest area that can range from mild to severe. Also known as thoracic pain, it's one of the most common reasons people rush to the ER—but not all chest pain is heart-related. Many assume any chest discomfort means a heart attack, but the truth is far more nuanced. Your heart, lungs, esophagus, muscles, and even nerves can all cause pain that feels like it’s coming from your chest. The key isn’t just where it hurts, but how it feels, when it happens, and what makes it better or worse.
For example, angina, chest pain caused by reduced blood flow to the heart muscle usually comes with activity and goes away with rest. It’s not a heart attack, but it’s a warning sign your heart isn’t getting enough oxygen. On the other hand, acid reflux, a digestive issue where stomach acid backs up into the esophagus can mimic heart pain with a burning sensation behind the breastbone—often after eating or lying down. Then there’s muscle strain, pain from overuse or injury to chest wall muscles or ribs, which gets worse when you move or breathe deeply. These are common, non-life-threatening causes, but they’re easy to confuse with something serious.
Red flags that demand immediate attention include pain that spreads to your arm, jaw, or back; sweating without exertion; nausea or vomiting with chest pressure; dizziness or sudden shortness of breath. These aren’t just symptoms—they’re signals your body is under stress. If you’re over 40, have high blood pressure, diabetes, or smoke, your risk goes up. But even young, healthy people can have heart issues, especially if there’s a family history. The goal isn’t to panic, but to know when to act fast.
