I would ask them about it tomorrow. Do you regularly get any blood with your bm's? If not, I would also ask them. I'd think that the blood would mean there's some inflammation somewhere. But, not panic mode quite yet.
I get blood off and on with my ulcerative proctitis along with some dripping blood. Mine will come mostly from stress or something I ate. I don't like it. But, it's something I have to keep a watch on and if I pass too much then it's time to contact my doctor.
I'd keep a watch on that blood though Ron. If you get continued dripping blood or are loosing too much blood, then I wouldn't hesitate to call. But, otherwise I'm just thankful to hear that you'll be going in tomorrow anyway. I hope this helps some. Xxxx
