My story is a long one, so to make it short....I was in the hospital for a kidney infection. I was on high dose antibiotics for two weeks. Now, the doctors think I have C.Diff. I have had diarrhea for about a month now...bad diarrhea! I am concerned about the damage that it can be doing to my body? I tried Metonidazole and it made me so sick. So, my doc just gave me Vancocin. Hopefully this will work, but I have been ill for about a month already through all the testing and follow up with my kidney infection. I even gave a stool sample and came back negative for C.Diff. Plus, I am in so much pain but the doctors dont want me to take pain meds for this. Does anyone know what kind of damage, if any, can be caused by C.Diff?? Permanent damage?
