Fibromyalgia is more of a "miscommunication or overreacting" of the perception of the brain and pain signals... not really mental health.... Although people do get depression because of the chronic pain and the chronic b.s doctors tell us...

I don't think menial illness is a cause of fibro, but it can certainly make them worse. I do think that mental illness and depression can be worsened by the disease.

Well, I don’t know if you read my post, but Dr. Terry L. Wahls will change your life! It’s all about diet and lifestyle. What you eat can be very damaging to your mind and body connection and yes there is a correlation between mental health and Fibromyalgia. The majority of cases of Fibro have been also diagnosed prior with depression and anxiety! If you study Dr. Whal’s she will show you how her MS was killing her, one disorder at a time. She displays what has to be done to become a survivor of Autoimmune disorders! Check it out, it’s all on the post! Thanks, my friend!

No, I don't think so. Some people, such as myself, do not have any mental health issues, yet still have the disease. The disease with me is very severe. What about if fibro was linked to other illnesses that are not mental health related. When you read posts after posts, think of all the other diseases people on this website have and could one play off of another? No one knows the definitive answer to that question, either. I wonder if it is multifactorial???

While fibromyalgia and mental health issues often overlap, it could be a case of causation vs correlation. Fibromyalgia could be causing the mental health issues or they could just occur together, and while it's possible that the mental health issues could cause fibromyalgia, based on the research I've read it's unlikely. There are measurable differences in the activation of the brain with painful stimuli (and even stimuli that shouldn't be painful), as well as changes in perception of cold and other things like that unrelated to mental health. People with fibro produce measurably less ATP as well "levels of creatinine phosphate and ATP are significantly lower (21% and 17%, respectively) in fibromyalgic muscle. In addition the synthesis of creatinine phosphate is defective. Thus energy metabolism in the fibromyalgia muscle is abnormal."
We also have changes in serotoninergic and catecholaminergic pathways, which are linked to also causing mental health issues, so I think the issues come hand in hand with fibromyalgia rather than being caused by it. It seems as though it is primarily genetic (most likely epigenetic, which could be why eating and exercising better can help, since those can physically help the "switches" flip back epigenetically).
Mental health is vital to address, but "fixing" it won't fix fibromyalgia.
