Hello dear, First of all, kindly do not get concerned regarding the thoughts of getting cancer. The symptoms as mentioned in your post is attributed to either infection or inflammation in the Gastrointestinal tract. Presenting with such symptoms, I usually treat my patients with: 1. Tablet Pantoprazole + Domperidone twice daily (to be taken half an hour before food) 2. Anti spasmodics like Dicyclomine preparation twice daily (to be taken after food). 3. Lactobacillus preparations or probiotics like enterogermina. 4. Antibiotics like Ofloxacin+ Ornidazole preparations, OR based on culture & sensitivity reports to control the causative organism. 5. Oral Rehydration Solution (O.R.S) for maintaining the hydration status & electrolyte balance of the body. 6. Take soft, plain, non-spicy foods. 7. Avoid fast foods & gas producing food products like cabbage, etc. So, the medications prescribed by your Doctor is correct, kindly continue them as advised. Wishing a good health. Take care.
