My child (2 years old) is suffering from colic before passing stool, touches his anus as it itches during bed time. We were giving homeo medicine for this issue. While taking cina 30 he is very much fine and just stopped a week before as he finished the prescribed duration. We were given him wormoid (full bottle completed) a week before but still we can see worms in his stool. He was fine while taking cina 30 but after completed he is having the issues again. Shall we continue with cina 30 for long duration? If so how long we can give him china?
