@wendyw. I had an FMT on February 28th. Mine was for recurring Cdiff. It definitely helped me. I’m not totally ok because I’m still having colon issues, but I’m in remission from that deadly Cdiff. I think the FMT saved my life. I certainly hope & pray it helps your Son.. My husband has kidney stones too & now he has one that’s too big for lithotripsy. He’s had laser by cystoscope & a lithotripsy all in the last month. Now he's facing major surgery to remove it. I’m so worried that he will get Cdiff from all the antibiotics they have given him & more to come I’m sure. I’m a believer in the FMT.
