Hi, Welcome to Healthcaremagic.com. I had gone through your question I can understand your concern about your stomach upset. Most important cause of heart burn or sour burping is acidity. Acid from stomach can regurgitate and cause mucosal erosion and next time when acid regular occurs there is burning pain. To avoid the pain at the time of burp take anti acid tab on syrup. There are many medication which helps to improve from it. Pantoprazole will be effective in your case, take one tablet daily in morning empty stomach. Avoid late night smoking, alcohol and food. Don t take anything two hours before sleep. Avoid junk and oil food for some time. Raise your head sides of bed, avoid exercise immediately after having food. Hope my opinion will be helpful to you and visit us back if you have any questions further to be answered. Regards Dr Muzaffer Hussain Parray.
