When should I be concerned about pain in the right side of my chest?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Right-sided chest pain is less commonly linked to heart problems than left-sided pain, but it can still signal a serious condition. You should be concerned if the pain is severe, persistent, or accompanied by warning signs such as difficulty breathing, fever, dizziness, coughing up blood, or pain that radiates to your arm, jaw, or back. Possible causes range from muscle strain and acid reflux to pneumonia, pulmonary embolism, or gallbladder issues.

Because the causes vary so widely, identifying the source of your pain quickly matters. A free, instant, online symptom check can help you understand what may be behind your discomfort and guide your next steps—whether that means self-care, seeing a doctor, or seeking emergency care. It takes just a few minutes and could bring you clarity when you need it most.

Explanation

Right-sided chest pain is usually caused by issues in the lungs, chest wall, or even muscle strain. Often, it isn't a sign of a heart attack because heart problems tend to produce pain more commonly on the left side. However, you should be more cautious if the pain is severe, doesn't go away, or if it is accompanied by other symptoms.

For example, if you have trouble breathing, feel dizzy, experience sweating or a rapid heartbeat, or if the pain spreads to other parts of your body, it could indicate a more serious condition. Also, if the pain started suddenly, especially after an injury or during physical activity, it's a good idea to seek medical attention.

Persistent or worsening pain might suggest conditions such as lung infections, pleurisy (inflammation of the tissue around the lungs), or even issues with the chest wall itself. To better understand what might be causing your symptoms, you can check your symptoms with our free AI-powered tool, which can help you evaluate your symptoms and determine the appropriate next steps for care.
