This came out after an enema in the morning – just this: not stool came with it. It was strongly holding together as one piece and I have not been eating anything apart from chicken/turkey breast, mushed rutabaga and overcooked cauliflower the week before it happened.
However, the test whether it is a worm came out negative even though a doctor who had examined it by eye claimed it was a tapeworm.
I am so puzzled!
