Hi, I have a doubt.. I bled and I saw blood on the toilet paper( I mentioned that before) I got the fecal immunochemical screening test two times in the last 2 years, both were negative. At rectal examination the doctor didn't notice any piles or hemorrhoids, not even lumps or tangible abnormalities. So the question is, piles are naturally and physiologically a part of our intestine and may cause bleeding when those are inflamed since I bled, otherwise I can't understand why I bled. Thanks
