@patts I know how it feels being scared of relapse. i had to take two courses of vanco back to back. I was very very scared of relapse. I am 75 and my c. diff like yours felt like it came out of the blue, but also like you i had previously taken a bunch of antibiotics. In any case I was otherwise in pretty good health. I lost 9 lbs and like i said I was scared of relapse. A good friend who was a nurse practitioner kept reassuring me that my constitution was basically strong and so I wouldn't relapse. And i haven't and it's been 7 months. good luck to you. I think it is very promising that you haven't lost eight and feel okay and no pain.
