Constipation lately due to taking adapex which led to what I think is a hemorrhoid. 2 days ago very painful bowel movements and slight bleeding from rectal area. Started ducolax and Metamucil (3x/day) 2 days ago. Had first bowl movement just now since then and it came out fine (no pain) but it had a long brown segmented string/yarn looking thing in the toilet. At least 10 inches long and had poop with it. I could easily break it apart with a straw and it did not appear to be alive or a living thing. Could this be from all the fiber I'm drinking or stuff purged from colon or a parasite!?!? Have a picture if ok to send please advise.
