teenage son?

[ilovemarkb]

Not a very nice thing to talk about but......... my son has been getting tummy aches......going to the loo and leaving a very smelly odour in the bathroom. Ive asked him if he is constipated or loose and he says his poohs are normal. What could be causing the tummy ache and nasty smell?

This is one of those rare occasions where I an grateful that I have absolutely no sense of smell!
