[|Human|] I went to the ER for some chest pains I was having as well as minor bloating with it. They did an EKG and a chest X-ray and didn t find anything. I later returned to the ER for some abdominal burning that was rather intense. (Enough so for me to go to the ER.) This made me assume it would be an ulcer and the doctor agree that a peptic ulcer is likely the culprit, however, without tests they can t confirm. I was told to go get ranitidine 150mg tablets and take them twice daily and after a few days it should help. I have been taking them twice a day, one around 12-1pm, the other around 8-9pm. The stomach burning has pretty much gone away completely, except after certain foods, however now I experience severe and long lasting heartburn for hours, sometimes immediately after eating food. I feel intense burning right at my sternum but no shortness of breathe. (Shouldn t be any, no lung problems. Also no heart problems so I m not too concerned about that.) I Also get the feeling of a lump in the base of my throat and the acidic taste in my mouth. Is this most likely a case of GERD? Or because of the ranitidine is there not enough acid in my stomach to digest my food pushing it back up?
[|AI|]  Hello dear, thanks for your question on Chat Doctor. In my opinion you are having HERD (gastroesophageal reflux disease) mostly, as your heart and pulmonary work up is normal.
