Good morning doctor, My 3ys son who has completed 2 recently has suffering from saviour constipation since 10 days. He is very much straining to pass the stool though We have given him lactulose solution. When we have consulted doctor he done enema and prescribed ODOXIL 125 DT and multivitamin syrup with zinc. But still the pbm hasn't resolved and he is crying while passing. Please suggest what to do. Thanks in advance.
