I have a stubborn case of cdiff. It’s been 5 weeks & 3 rounds of flagyl. It comes back after about 4 days off meds. I’m on vancomycin now. He prescribed 2 weeks. I have one more week. I’m getting anxious. My diarrhea had stopped but I’m so weak that my legs shake if I do much of anything. I’m 71 & got it from vancomycin for a severe sinus infection. I have lost 20 pounds. I’m at 85 now. I’m also lactose intolerant. I had a case of ischemic colitis 10 months ago. After that healed I had an upper & lower scope & several ct scans & 2 MRI’s. Any suggestions??
