So two weeks ago I was constipated so I drank probably a pint of prune juice and it all came out, a lot of prune juice, straight prune juice came out. The past 2 weeks I have had irregular bowel movements, small ones, big ones, and since the last two days I have seen what seems to be oil or reddish orange grease coming from my anus when I fart or poop, anyone have an idea of what this is?
