hey i suffer from the same thing, you should get him to have a ct scan.
I have a calcium stone just behind my belly button, there is a tube that goes from your bladder to your belly button and this is where it was found. I get stitch like pains in a line down from my belly button, it causes me to have bladder problems and i cant exercise without gettin stitch within 2 minutes. The told me it was because there was a build up of calcium in the umbilical cord when i was a baby and when it was cut it was left behind. i was told it makes me more susceptible to infection. now im waitin to see if it is definately the cause of my bladder problems. it causes pain on and off it is not constant. I hope this helps you, im 19 and have only just discovered it, hopefully if it is the same they will find out before it becomes a bad problem. also check if he is gettin discharge from the belly button. good luck!
Hi...is he moving his bowels daily and large enuff......sometimes the bloating from not going regularly can cause those types of pains.
Try to keep a journal as to what he eats and when he goes ect....
I pray u find the answer soon
