I pooped out little black balls. Lots of them. I had diarrhea all day. My first stool had no black balls, my second did.
I've had lots of black berries lately, and ate fish (tilapia) for dinner a few nights ago.. I wouldn't think it was the black berries because iv'e always eaten them and have never seen this before. I'm very healthy/ young (I run cross country for my high school- 5+ miles a day). Just a little worried as to what this is ( read that little black balls in poop might point towards blood problems).
please help me?
