Hi. Thanks for your query. Noted the history and understood the concerns. Eating outside the house and developing dysentery, nausea, joint pains and fatigue is surely indicative of an intestinal infection and amoebiasis can be co-existent. Hence I would advise you the following: Consult your Doctor for clinical evaluation, examination and advise the tests of stool, blood and urine. Get a course of an antibiotic, metronidazole and as per the reports. Take probiotics, bananas, curds and rice. Plenty of oral fluids, boiled and cooled water and soft bland diet. So not eat outside, always have homemade fresh foods only to avoid re-infection.
