My son is having constipation problem from past 1 month, we have done stool test, ultrasound abdominal test and thyroid tests. Everything came out to be normal. And still after everything seems normal he is crying lot while passing stool.We are following proper medication and giving fluids and fibre food, but still no improvement in his condition.Please help us what to do? P.S: Currently we are using Aristozyme 1ml, Lactihep 5ml, Colicaid 5ml, Sorbiline 5ml. My pediac says it takes lots of time to cure, but as father i am unable to see my son crying whenever he passes stool.
