I have had gastrointestinal issues for the past 15 days. I experience loose, greasy, sticky stool along with burning upper abdominal pain and bloating, especially on an empty stomach. I feel trapped gas that rarely passes, and when I try to burp, it feels like food is coming up sometimes . My symptoms worsen after consuming wheat roti , milk tea but improve when I avoid them and take probiotic curd. In morning I feel bloating, burning , pain but when I take curd with sugar it feels better and cool .I also have minor itching on my forearms, elbows, and back for last 2 days and a history of vitamin B12 deficiency. What could be the underlying cause?" Doctor prescribed me - Prebiotic and Probiotic Capsule Pantoprazole Sodium EC + Domperidone SR Capsule Ornidazole Tablets 500 mg Drotaverine and Mefenamic Acid Tablet Liver and Enzyme Tonic
