my baby is 3yrs old.She is having stomach ache in her left side for last 4days...after having her meal.But sometimes,when she is hungry,she also suffers from it. She does not have any vomitting tendency,nor fever. Before,she used to had motion every alternating day,but now,she is doing it twice a day(after taking meal). I can feel that,she passes air. My doctor advised to give herLANZOL 15 ONCE IN A DAY(for 20days).

Please Advise me....
