When Should I Seek Medical Attention for Chest Pain on the Left Side?

You should seek medical attention for left side chest pain—especially if it's new, severe, or comes with other symptoms like difficulty breathing, pain spreading to your arm or jaw, sweating, or dizziness—since these could be signs of a heart attack.

Explanation

If you experience chest pain on the left side, it's important to pay attention to your body. You should call emergency services or go to the hospital right away if the pain is sudden, severe, and accompanied by other worrying symptoms like shortness of breath, nausea, sweating, or pain spreading to your arm, neck, or jaw. These symptoms may be signs of a heart attack or other serious heart problems. Even if the pain is not severe, if it lasts longer than a few minutes, keeps coming back, or if you have a history of heart disease, it’s best to have it checked by a doctor. Sometimes chest pain may be due to other causes such as muscle strain or acid reflux, but because heart problems can be life-threatening, it's better to be cautious. Your doctor can ask you questions, perform tests, and determine if the pain is related to your heart, lungs, or another part of your body. Getting professional help ensures you receive the proper care to keep you safe and well.
