If one has endo in rectum does it bleed without a BM? Only when I went for a wee today I noticed bright blood from anal area when drying . This happened once before exactly 1 month ago. I know I have a nodule on rectum but also have constant throbbing soreness inside of lower rectum. Possibly a haemorroid I suppose .all a bit weird . Colonoscopy 2 years ago negative!
