Do you believe that we fibro people have excess phosphates in our bodies that doesn't get excreted by the kidneys therefore causing alot of pain?. I mean I wake up at night and in the morning and can barely walk. My low back and hips and buttocks feel sooo sore and tight. I am thinking of going back on the guaifensen. I quit when they took it off the market as a script. I bought some from this site andd I remember feeling better so, guess I will try it again and stick to it.
