Very interesting post. I am searching for a connection for all this mess also! I have endo, pcos, insulin resistance, and chronic migraine. I have many symptoms of fibro and my mother has it...but when you have the migraines they don't diagnose fibro.
All go back to poor immune system. I also have very low vitamin counts and take alot of vitamins to make up for it.
Could be part of a sensitivity but I haven't really read much about it. I know all of them respond better on the low-glycemic diet....my mother is doing with me, with low sugar and feels great!
(meds....topamax, januvia)
