five years ago I had a sinus infection and two docs gave me several antibiotics, I kept saying they were making me very, very sick til my husband took me to the docs and I passed out so she called an ambulance, I had cdiff four times and finally they did a fecal transplant, lost 20 pounds. My gut has never been the same then I got a uti last month and had to take an antibiotic for three days but it didn't get rid of the infection so took another for 5 days and still feel sick. I have taken a probitotic for all these years but GI doc said to take visbiome for two months as he suspects I will get the cdiff again. I am a wreck, I have a brain tumor that has been scaring me but the thought of cdiff again did me in. I told the doc the antibiotic was making me very sick and he said it was all he could give me so take and put up with the side effects!
