What might cause chest pain that lasts all day?

When you have chest pain that does not go away and lasts all day, it might be coming from different parts of your body. One possibility is that this pain is related to a heart problem. Sometimes the heart does not get enough blood, or it might work hard, and that can cause a steady kind of pain. However, many times long-lasting chest pain is not from the heart. It can be caused by acid reflux, where stomach acid moves up into your chest and causes burning and discomfort. Another common cause is costochondritis, which is when the cartilage that connects your ribs to your breastbone becomes sore or inflamed. The pain can also come from muscle strain or tension in the chest, perhaps made worse by stress or anxiety. Either way, it is important to talk with a doctor about any pain that lasts all day so they can help figure out what is causing it and make sure you get the right care to feel better.
