I was in the hospital for 10 days in July with c diff, severe hypokalemia and magnesium deficiency. I should mention I have been in the hospital 11 times in a year for cellulitis and now have lymph edema. On 8/12 c diff is back and I have the worst SLE flare of 44 years. I'm not in the hospital this time and was put on oral vancomycin and steroids. Now I'm off the vancomycin due to Barrett's esophagus and start flagyl tomorrow. What in the world can I do to get rid of the c diff? I'm so tired of being ill.
