I get stomach infection every month. When i get the infection. There is smelly flatulence and i have to visit the washroom 3 times a day anf there is slight cramp usually in the morning for 2 mins appprox. My family doctor says that i have gastro so i am bound to catch infection easily. Everytime i visit him he gives a 5 days medicine of either flagyl or ziffi , amoxicillin or some other antibiotic and i become alright. But the problem reocurrs after 1-2 months. Pls advise how do i get rid of this problem permanently..
