Well, this proves to be a very interesting read and something to think about:

It is a scientific study that really rings true to many of the varying symptoms ranging from one fibromyalgia sufferer to another... and why is there such a strong correlation to clusters of symptoms i.e. Irritable Bowel Syndrome etc.

I always feel like I am learning more and more about the possibilities of causes and reasons for Fibromyalgia, and the pain and suffering of this syndrome!  I hope that the scientists (such as these in this study) continue to try and put 2 and 2 together for chronic conditions.  It is not easy not knowing, and not easy when people have preconceived ideas about Fibro or any other condition that doesn't have a 'disease' branding (ie. therefore not real in the medical world). 

It just proves that we don't know as much as we think about our bodies, in this article it explains the hundreds of thousands of unknown bacteria we have in and on our bodies.  Some say we don't even know the life cycle of them.  Also that we didn't think they could transfer DNA to one another... there is so much more to learn!!
