I have just signed up on this site because I was looking for ansews for what I have. Then I seen your email on here so wanted to reply to it and let you know that I have the same thing. It sucks!!!!
I have been told that I have I.B.S.. a few years back. So when I get this happening to me, which what is going on with you, I just think, well ok, I am having a i.b.s. Attack.. But i read somewhere that penicels size stools could also mean a sign of colen cancer. So Now I freak every time I have these penicels size stools. Which I have been having for about two weeks now.
Anyway you could be just having a i.b.s attack and need to eat allot of fiber to get it under control but you should make sure you get to your doctor and have him do a colen test on you to make sure noting is wrong.. I had one of those but need to go have another one. YIKES!!
Anyway I sure would like to know what you fined out about what is going on with you.. It would save me a trip to the dang doctors. (smile).
But please make sure you get checked out for I.b.S. and have a colen test done.
