question: My 3 yr old has been very constipated for 2 yrs now. He's on movical & pico syrup. He got an X-ray last week but showed nothing. So nw they are doing a scan of his tummy because since been on the movical he has had diarrhoea for the past 9 weeks. Also as sore tummy. Always tired. Not a very good eater. Also is as white as a sheet. Any advice please.
