Patient discussion about matching

Q. Hi members, after I notice that our symptoms match those of fibromyalgia. Hi members, after I notice that our symptoms match those of fibromyalgia, do we have to live with it and simply manage it for the rest of our life or try some luck with food and meds? Thanks.

A. If you could have given a particular age details then it could have been easy to analyze. This condition is relatively new, yet it's appearing in epidemic numbers. Dr. Whiting (an orthomolecular nutritionist), finds in his work with people suffering with this that they are all very toxic. When their systems have been properly detoxified their symptoms will disappear. His personal feeling is that this is a condition of hyper-toxicity and manifests itself in people who are unable to physically cope with the overload of toxins in their system.
