Last time I went to the doctor with it when he was 7 the doctor said we can't do any tests because it isn't bad enough (back then he had the runs really bad atleast once a month and often complained of tummy ache) but now it's once a week. Is that bad enough to go and see the doctor again, they always make me feel as if I'm bothering them somehow. And it's cold and I have to keep opening windows to let fresh air in
