What might cause chest pain on the right side of the chest?

When you feel pain on the right side of your chest, it usually does not mean there is a heart problem. Instead, it can be caused by issues in your lungs or the tissues of your chest wall. One possible cause is pleuritic pain, which happens if the lining around your lungs becomes inflamed. This makes your chest hurt especially when you breathe in deeply or cough. Another possibility is hyperventilation syndrome, where breathing too quickly or shallowly (often from anxiety or stress) leads to chest discomfort. Additionally, some people may experience a condition called Mondor’s disease. This condition involves inflammation or a small blood clot in the superficial veins on the front of the chest, which can cause pain in that area. Since right-side chest pain generally originates from these non-cardiac causes, it is important to have any persistent or worsening pain checked by a doctor. They can review your symptoms and may do tests to find the exact cause and decide on the best way to help you feel better.
