my 13 week old has for the last week been soley on formula - he has heinz nurture gold then he got constipated - 3 days no poop then i moved his legs etc gave him water and he eventually went it was fairly firm and he screamed his heart out when he did it, i gave him some coloxyl infant drops - advice from the pharmisct..... he went this morning and it was failry runny, Now approx every 5 or so minutes he screams in agony and has episodes for approx 1 1/2 hours at a time...

I dont know whats wrong and its breaking my heart that i cant do anything to take away his pain...
