I know this is a gross question -- sorry! -- but maybe one of you can help. This may be IBS related, maybe not, I don't know... I had my first colonoscopy 7 days ago and two polyps were removed, one rather large and flat, which required an extensive excision. My stools have been relatively speaking okay since then (within my usual IBS-D range), except that they seem to be covered in a kind of loose, dark green, mossy-like weird substance. For me this appearance and consistency is quite unusual. I sort of expected it to go away 2-3 days after the colonoscopy, but it hasn't yet. I'm wondering whether anybody else has had this experience after a colonoscopy or whether i should just chalk it all up to the weirdness of my IBS (the diagnosis of which has now, after the latest round of tests, been "confirmed" as post-infectious IBS-D). Thanks for your thoughts.
