Dear Patient, Welcome, and thanks for sharing your concern I went through your query, and and let me warn you that you are holding a wrong misconception, blood in your stool is due to some problem with your lower tract, anything from piles to tumor can cause such bleeding, but be sure its not because of disc, I would want you to consult your surgeon to get your rectum and anus examined and see for the cause of bleeding, because with time you will develop anaemia, and than the things will become out of control, so do not waste time and act fast I hope my advice would have been useful, in decision making regarding your treatment, still if you have any clarifications or doubts feel free to contact back. Thanks.
