What Causes Pain on the Left Side of the Chest?
Pain on the left side of the chest can be caused by a variety of medical conditions, including gastrointestinal, muscular, and cardiovascular issues. Pain on the left side of the chest can range from a dull ache to a sharp, stabbing sensation and can be mild or severe.
Gastrointestinal Causes
Pain on the left side of the chest can be caused by gastrointestinal problems, such as acid reflux, heartburn, or an ulcer. Gastroesophageal reflux disease (GERD) is a common cause of pain on the left side of the chest. GERD occurs when stomach acid moves back up into the esophagus, causing a burning sensation. Other symptoms of GERD include difficulty swallowing, chest pain, and a bitter taste in the mouth.
Muscular Causes
Pain on the left side of the chest can also be caused by muscle strain or injury. Overuse of the chest muscles, such as from repetitive movements or lifting heavy objects, can lead to chest pain. Other causes of muscular pain on the left side of the chest include fibromyalgia, a condition that causes muscle pain and fatigue, and shingles, a viral infection that causes a rash.
Cardiovascular Causes
Pain on the left side of the chest can also be caused by cardiovascular conditions, such as a heart attack or angina. A heart attack occurs when the blood flow to the heart is blocked, usually by a buildup of cholesterol or fat. Symptoms of a heart attack include chest pain that may spread to the arms, neck, jaw, or back, shortness of breath, and nausea. Angina is chest pain caused by reduced blood flow to the heart.
If you experience chest pain on the left side, it is important to seek medical attention to determine the cause. Your doctor may order tests, such as an electrocardiogram or blood tests, to diagnose the condition. Treatment for chest pain will depend on the underlying cause.
