Have you taken many antibiotics in your life? Had a bad stomach virus with diarrhea prior to the symptoms? SOME of these symptoms sound like a Candida Albicans problem. When you have a kill-off of bacteria in your intestional tract, and the yeast takes over -- you have problems -- sometimes BAD problems. You have to re-establish the "balance".

Google "The Yeast Connection" and see if any of this rings a bell.
