Hi, Thanks for writing your query. After reading your post, it seems that you might be having infection of the gastrointestinal tract and needs medical management. You should take an antacid like Omeprazole 40mg once a day before meals along with an antibiotic and antiamoebic. A probiotic will have added benefits. You can take dicyclomine for abdominal pain. Eat light meals prepared under hygienic conditions. Also take care of your hydration. I hope this is helpful to you. Thanks.
