there are also those who had fibro and were treated for depression, and the fibro magically dissapeared. imo fibro seems like IBS, they know somethings wrong, but they just leave it at a blanket statement because they're not sure why you're in pain with no blood work showing anything.
actually, there are some theories that suggest, chemically, what is going on with fibromyalgia that make it nothing like IBS in the "wastebasket syndrome" category. CSS (central sensitivity syndrome) diagnoses share some commonalities when it comes to brain chemistry, particularly in the reduced functionality in the parasympathetic nervous system. at least one theory suggests this is because the sympathetic nervous system is running so "hot" for so long (due to the excessive non-physical stresses that we put on our body, in comparison to the sum total of stresses that our body used to deal with tens of thousands of years ago) that we've burnt out our parasympathetic nervous system, to a certain degree. (we end up producing insufficient quantities of dopamine and seratonin, for starters.)
the problem is that the chemicals that are affected are very difficult to test for in the general blood system, and going in and testing chemical levels in the brain is too invasive of a diagnostic test for every day use. additionally, they're still studying fibro patients to find out what the differences are in general. hence the lack - so far - of standard laboratory tests.
as for the original question, I'm one of the opposites. I had been gluten free for four years, and casein free for three (and soy light for two or so), and was diagnosed with fibro early last year. were pretty sure we caught it rather early, and it's quite likely that it's stress induced in a very "classic" way. but you may find that it was a mis-dx for you; the only way to know is to try the diet and see how you do! good luck!
