I always pass mucus/ tissue when I have a BM. It is not mixed in with the poop, Its separate. I recently had a colonoscope and I am in remission, but I was diagnosed with a severe fissure. Could it be from this?? I have mentioned it to my Dr. But he never really said much. I have had this for a long time, I pretty much don't know any different, but would like to know what it's from. Anyone else have this??
