Hi - I have had diahrrea for about two months from taking Clindamycin. My doctor doesn't seem very alarmed and has recommended taking probiotics. I have taken Floragen for about five weeks now, but, still not back to normal. Ocassionally, I will notice just a very little bit of blood in the stool... and several stools on a daily basis are watery / with some mucus. I am worried about having C-diff. However, he doesn't think that is the issue. Has anyone had these symptoms and fully recovered by taking just yogurt or a probiotic?? Thanks!
