Thanks for your question on Chat Doctor. I can understand your concern. Yes, this kind of sensation can be due to gaseous distention of stomach. Since your chest x-ray and ECG are normal, no need to worry about heart and lung diseases. Gaseous distention of stomach can cause similar kind of moving sensation in the chest. So take proton pump inhibitors and prokinetic Chat Doctor.  Avoid stress and tension. Avoid hot and spicy food. Avoid junk food. Avoid large meals, instead take frequent small meals. Go to walk after meals. Quit smoking and alcohol if you have these habits. Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
