I am usually fine all day, then at night I experience fluttering high in my chest, and burping, as if something has not gone down. No pain, it only lasts for seconds, and it has only been happening for a week now. I am 50 and in very good health. At one point I thought it could be my vitamins getting stuck and not going down correctly.  I stopped taking them(2 days ago). What can this be?
Hi. I can understand your concern. HERD (gastroesophageal reflux disease) can cause similar kind of chest pain. HERD 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 discomfort. Take proton pump inhibitors. But along with Chat Doctor.  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. Lose weight if you are obeseDont worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
