You definitely should consult a Dr., as rectal bleeding could mean a colon problem. Good luck1
It sounds like some kind of perforation or tear that has become infected. You really should see a Dr. as this could be or become something very serious. It may be internal hemmorhoids, which are usually painless, and unseen. If one tears, it can bleed quite a lot. But the "green slime" is another issue that would suggest something more. Good luck.
Oops, good catch. Meant rectal. Thanks for the catch. Not Hemorrhoids.
Renal means kidney. Is that what you meant, or did you mean rectal?
