Hi, your symptoms could all be attributed to GERD, (Gastro Esophageal Reflux Disease), where the acid contents of the stomach
come up into the esophagus. Since medications don't seem to be helping much why don't you try life style measures? Take frequent small meals. Eat dinner about two hours before sleeping. Elevate the head end of the bed. Keep a food diary and note down what aggravates your symptoms and avoid them. Ensure to maintain optimum weight by regular exercise.
