Hello. I have just taken 2 kinds of antibiotics (not at the same time) for a tooth infection. Cephalexin and Clindemyecin. I started off taking the Cephalexin, felt it wasn t working on my infection, so started a round of clindemycin which did help with the tooth infection. AFter part of my root canal was finished I continued to finish up the Cephalexin because I was afraid the infection would return before I was able to get in to have my root canal finished (which happened finally yesterday). I haven t taken any antibiotics since last Friday morning and over the weekend, I felt pretty good, but yesterday I started feeling very sick and had very painful strained diarrhea. It has continued today but is a little better than yesterday. I m very scared because I ve heard so many stories about C. Difficile. Should I wait it out a few more days, and if it doesn t resolve itself, go see a doctor then?
