Thanks for your question on Chat Doctor. By your history and description, you are mostly having HERD associated pain. But better to rule out cardiac cause first because you are hypertensive. So get done 1. ECG 2.  2d echo 3. Stress test. If all are normal then you are mostly having HERD. 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 Central burning chest pain and gaseous feeling in stomach. So avoid stress and tension. Avoid hot and spicy food. Avoid junk food. Start proton pump inhibitors. Don't worry, you will be alright.
