<s>[INST] I am having heartburn (burning sensation) in the middle of the chest on and off for the last one month and also slight back pain at times. Burping occurs sometimes also. ECG is normalI have been taking Rozavel FLS for the past one year and also Pan-D for acidityWhat to do? [/INST] Hello are rightly taking Pan-D for acidity. It is a combination medicine of proton pump inhibitor and risperidone. Persistence of acidity may be due to bacterial infection in stomach or duodenum by bacteria like H. Pylori. You may need clinical correlation and further investigations like ultrasound of abdomen and upper GI endoscopy. Biopsy may be taken during endoscopy. You may need specific medicines for H. Pylori. It is good that cardiac status has been evaluated. You should continue Ravel medicine. Get well soon. Take Care Chat Doctor.  </s>
