I have been on heavy antibiotics to treat a bacterial infection, and also take probiotics to counter-effect the antibiotics bacterial removal. For the last week, I have noticed red spots on my stool. The stool color is normal brown, and the spots are one or two. Afraid, I examined one or two of the red spots. They were very skin-like, like some kind of tomato skin. They did not dissolve in water and required some pressure to be split into two. The pieces are tiny, less than 10mm. Any clue what it may be? Does blood congeal into a skin-like substance? I am trying to see a Gasentrologist but these guys are so busy during holiday season.
