Hi,If you have had all the tests, I wouldn't worry about the blood too much. I do have internal hemmies and diverticulosis along with my never-ending "C" and occasionally I notice blood tinged mucous. It used to freak me out too, but my doctor told me it is most likely an irritation of sorts. Just like if you have a cold and continually blow your nose, you will sometimes see some slight blood with the mucous. The colon can get irritated in the same way. If it continues, call your doctor, if for nothing else to put your mind at ease.------------------"Remember To Stop and Smell the Roses"Rose (C-type)
