I have been searching and searching for some clue as to what these "balls" or "stones" might be. I too have never been able to find a picture that looks like what I have come out of me also. They are about the size of a grape, smooth and white and there are times that I have 2 and 3 come out at the same time. I take psyllium about every other day and that is when they seem to come out mostly. I get them coming out pretty regularly since I've been taking the psyllium (about 3 months now). I would love to know what these are. Thank you in advance (anyone and everyone).
