Thanks for your question on Health Care Magic. I can understand your situation and problem. By your history and description, possibility of GERD (gastroesophageal reflux disease) is more. 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 of burping, central substernal chest pain etc. So avoid stress and tension. Avoid hot and spicy food. Avoid junk food. Drink plenty of fluids orally. Start proton pump inhibitors and prokinetic drugs. 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.
