What Are the Causes of Pain Below Sternum?
Many conditions can cause pain below the sternum. According to the American College of Gastroenterology, or ACG, abdominal pain can occur throughout the abdomen or in one specific abdominal location or quadrant. Some types of abdominal pain manifest in the upper middle part of the abdomen, below the sternum or breastbone. Pain in the upper middle abdomen may be mild, moderate or severe, depending on the cause of the pain and the tissues involved.
