[/INST] Thanks for your question on Chat Doctor. In my opinion you are having HERD (Castro Esophageal Reflux Disease) mostly. But better to rule out cardiac cause first. So get done ECG. If this is normal than no need to worry much. It is due to HERD only. It is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause the symptoms. Try to follow these steps for better symptomatic relief. 1. Avoid hot and spicy food. 2. Avoid large meals, instead take frequent small meals. 3. Avoid stress and anxiety. 4. Start proton pump inhibitor. 5. Go for walk after meals. 6. Keep 2 - 3 pillows under head in the bed. 7. Avoid smoking and alcohol if you have this habit. 8. Lose weight if you are obese. </s>
