I'm sharing an articles posted on the Fibromyalgia Network Facebook site which helps to prove that Fibro causes the depression, not the other way around.:

Elevated Protein in Fibro Patients shows it’s not depressionby Fibromyalgia Network on Friday, December 3, 2010 at 10:16am


Tired of hearing that your fibromyalgia is just a form of depression? Brain-derived growth factor (BDGF), a protein found in the serum, was shown to be elevated in fibro patients.* However, in people with depression, this same protein shows up at lower than normal levels. The finding in FM was not influenced by age, gender, disease duration, or whether patients were taking antidepressants for the treatment of their pain. These are all favorable qualities when looking for a disease marker, and the fact that BDGF can be measured in the serum makes it relatively easy to analyze. But what does this protein have to do with pain?



BDGF is a mediator of pain in the peripheral nervous system and has been found elevated in association with the pain of pancreatitis. So not only do these findings on BDGF show that fibro is not caused by depression, a higher-than-normal level in the serum provides yet another objective measure that your pain is real.



But you already knew fibromyalgia was not depression, didn't you.
