Thanks for your question on Chat Doctor. I can understand your concern. No, this is not heart attack or cardiac chest pain. You are having HERD (gastroesophageal reflux disease). Your chest pain is associated with eating and relieved by water and die gen (antacid), so HERD is more likely in your case. You need to follow these lifestyle changes for better symptomatic relief in HERD. 1.  Avoid hot and spicy food. 2. Avoid large meals, instead take frequent small meals. Avoid junk food. 3. Keep 2 - 3 pillows under head in the bed to prevent reflux. 4. Take proton pump inhibitors and prokinetic Chat Doctor.  5. Avoid stress and tension, be relaxed and calm. 6. Quit smoking and alcohol if you have these habits. Don't worry, you will be alright after following these things. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
