This was taken verbatim from a co-cure chat group.  My personal experience has shown that bacterial/fungal dysbiosis of the gut can play a strong role in CFIDs as well.  C. difficile is indeed a toxin producer which is consistent with many of the new research findings, such as those being published by Ritchie Shoemaker, at www.biotoxin.info.

 I ” had” Fibromyalgia and was accidentally cured and no one will listen - Suggestion for resarch
I was well on my way to being diagnosed with fibromyalgia by my doctor after 20 years of living in pain. I was deteriorating, and the low grade fevers, diarrhea, and exhaustion drove me to insist that I was sick, really sick. After three office visits and many tests, I began to feel that I was being treated like a hypochondriac and the doctor was starting to become openly disbelieving. After waiting a long time on the third visit, the doctor finally came in and gave me an apology. Seems they found a thriving colony of c-dif bacteria in the latest test results. She kept asking if I had been in the hospital lately. The answer was no. I was given a round of antibiotics that helped some, but did not do the trick. They gave me a much stronger and longer second round of antibiotics and I got much better for a few days. I went back to get more antibiotics when I began to relapse, the doctor refused, and I got very cranky. She relented and I got the antibiotics but she was very unhappy with me. At the end of that round of antibiotics, I was well! And PAIN FREE for the first time in twenty years! That was 19 months ago. Two or three months ago, the chronic pain started again although at a much lower level. I went into denial and ignored the pain (hoping that if I did not face it, it would go away like magic?) as much as possible. About 6 weeks ago, I developed an inner ear infection and went to the doctor for the first time since I had gotten so cranky with her. She gave me the puny antibiotics again and after a week and a half, the ear infection was back. This time she gave me Septra for 14 days. You can guess the end of the story. I feel young, I can get out of a chair without thought, I get up and down off the floor, and I lead a normal, pain free and active. I can do any/every thing I want. There is no pain. It doesn’t even cross my mind.Maybe it could be coincidence that all those symptoms went away the first time I took multiple rounds of antibiotics, but just what are the odds of it happening twice? Without the c-dif infection and then the ear infection, I would still be leading a life of pain filled desperation. Maybe this is not the answer for everyone, but what are the chances that I am the only one?
