Hi I'm not sure if I've put this in the right area but need some advice. My ds just turned 18 and had just told me lastnight when he went toilet there was blood in toilet bowl. He said this has happened before. I've told him he needs to see GP asap but he's refusing as he is thinking of joining the army and certain medical problems won't allow you to enter such as IBS and Crohn's. I've tried pursued him go today but need to ring at 8 and he refused and said he'll go next week. I'm worried sick. Has anyone's older child had this. My grandad died of bowl cancer when I was 15 so my mind is all over the place. Any advice please would be so appreciated. Thanks.
