hey mate, basically 7 months ago i passed a small amount of blood, the doctor put this down to strenuous activity. i then had a thyroid test a few months ago and the test came up unusal, i was supposed to get another test a few months after but never did. then early this year i fainted a few times and was constantly feeling unusal. for the last 2-3 weeks i have had on and off diarrhea. today i shat complete blood, the whole bowl was red and splatter arund the bowl. the blood was light in coulour and the poo was also light in colour. i went to see the docto and he put this down to hemorrhoids. i just passed again and the blood was alot darker but not as much of it. i feel uneasy with this diagnosis as i am only 18. thanks, kale wren.
