For the past few months, I have had pain in the middle of my chest at night. Sometimes the water in the stomach refluxed up, causing me to choke and cough. In addition, I do not eat enough, every time I eat, I vomit a lot of saliva, sometimes even review food. Because of the epidemic, I couldn't go to the hospital. The doctor asked me, what is the sign of vomiting after eating?

When I eat, I vomit, often have indigestion, when I vomit yellow fluid. I had pancreatitis before. Doctor tell me what is vomiting after eating with indigestion? What treatment do I need? Thank you doctor.
