[/INST] Thanks for your question on Chat Doctor. In my opinion you are having mostly HERD (Gastroesophageal reflux disease). But better to get done ECG to rule out cardiac cause first. If ECG is normal than no need to worry much for cardiac cause. You mostly have HERD only. For HERD, along with Chat Doctor.  1. Avoid stress and anxiety.2. Avoid large meals, instead take frequent small meals 3. Avoid hot and spicy food.4. Go for walk after meals.5. Keep 2-3 pillows under head in bed to avoid reflux.6. Lose weight if you are obese.7. Avoid smoking and alcohol if you have these habits. </s>
