Can Metronidazole Cause Red, Itchy Rashes And Blisters On Body?

I had a diagnosis of C-diff on 2-13-15. I m taking 500 mg of metronidazole 3 x daily and florasdor 2 x daily. Diarrhea has completely stopped but now I have a red rash on hands, stomach area, and legs. It is itchy and there are blisters in some areas. I have 9 more pills of metronidazole to take before 14-day dosage is used.
