Sometimes I get a pain in my chest that is kind of like a pinching feeling. What can be causing this?

Many possibilities. Chest pain can come from many causes including heart, lungs, esophagus, rib cage and others. Not knowing your age, health history, family history, smoking history, cholesterol level, and additional information specific to this pain, it is impossible to tell exactly what is causing this pain. Best to see your family doctor or internist for a definitive answer as to the source of your pain.
