Since it is bright red it is indicative of bleeding in the lower portion of the bowel. I had this while I was hospitalized last year and YES it is scary. I am not familiar with CDiff but know I was tested for it last year and I didn't have it. You're doing the best thing by calling the doctor tomorrow. Let us know how you make out ok? Good luck.
