Hello, Most probably an acidity, gastritis and reflux disease. Do you also have upper abdominal pain, nausea, bloating, burping, increase in pain on food, sour water feeling in throat or chest burning, these are the other symptoms. Still there is no harm in getting ECG and stress done to rule out cardiac cause. You should avoid fatty, oily and spicy diet. Have some walk after having food instead of taking rest. Have multiple small meals instead of heavy meals. Have regular sleep habits and avoid stress. Avoid smoking and alcohol if any. You can get prescribed tab Pan DSR 40 mg or Esomiprazole Domperidone combination before breakfast once a day for 2 weeks. If not adequately relieved, then you should add Gelusil two teaspoon three times a day for a week. Hope this helps you Get back if you have any doubts Regards Dr. Sagar Makode, Cardiologist
