<s>[INST]I have a pain in my chest, feels like the sternum region, when I drink hot liquids (coffee).  My sternum region feels like there is a "bulge" or something in it that needs to be removed..no pain unless I drink hot liquids or eat a hot meal like oatmeal.[/INST]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 pain and nausea. You can 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.</s>
