Has anyone had a bowel movement that was fully covered with dark blood? I had that in April, for one day then I used the cortifoam that evening and the next two day, and it went away. My CBC was also ok 3 months later when I had it done, but prior it was alittle low. I have Crohns in my large intestines.
I had a very bad bacterial food poisoning a few years ago and I had the same type of thing in my stool.
Get checked for things like Campylobacter bacterial infections. They will need a stool sample for this.
Weird, I'm not sure what the flesh thing is but are you sure it wasn't food that wasn't digested properly?
