Thanks for your question on Health Care Magic. I can understand your concern. Ideally ecg and 2d echo should be donedone first in your case. If both are normal than no need to worry for heart diseases. GERD (gastroesophageal reflux disease) can cause similar kind of chest pain. GERD is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause central chest pain and nausea. You are taking proton pump inhibitors (pepcid). But along with drugs you need to follow certain below mentioned lifestyle modifications for better symptomatic relief. Avoid stress and tension. Avoid hot and spicy food. Avoid junk food. Avoid large meals, instead take frequent small meals. Quit smoking and alcohol if you have these habits. Go for walk after meals. Keep 2-3 pillows under head in the bed to prevent reflux. Loose weight if you are obese. Don t worry, you will be alright with all these. Hope I have solved your query. Wish you good health. Thanks.
