what causes pain in between your shoulder blades when you are sick
One of the possible causes of pain between shoulder blades is a heart attack. This occurs when a build-up of cholesterol, fat and other substances block blood flow to the heart. The interrupted flow of blood can damage areas of the heart muscle.
Cancer: Certain cancers such as Pancoast tumors may cause radiating pain felt between the shoulder blades as it pushes on nerves near the top of the lungs. Other cancers that can cause a similar presentation include esophageal cancer, mesothelioma, lymphomas, and liver cancer.
