I have not, but disassociation is one of the worst symptoms of my panic disorder. I don't disassociate with regular anxiety (anxiety due to work etc. Stress). I only disassociate when accompanied with paranoid thoughts. In this past this was linked with an OCD diagnosis. But I don't really like to label myself as that because I haven't been extensively attentive to it. If I had to guess, any sort of panic disorder is going to correlate to fibromyalgia because you are putting your body through emotional and physical stress. The constant clenching and releasing of the muscles and other reactions could be aggravating your fibro.

You aren't alone.

If it helps at all, I have made great strides with panic disorder. I've gotten my triggers down to a handful of things. Typically only fear of being on medication or accidentally consuming medication (being drugged) are the only thoughts that trigger disassociation from me. Its funny that the fear of being on drugs causes my brain to *feel* like its on drugs. I'm hopeful that over time I can start to overcome this as well.

Hope you feel better soon.

Sounds more specifically psychologically based? Although any adult illness including fibro can come from childhood trauma and the subsequent stress from those experiences.

One theory is that FND results from an "internal conflict," and the symptoms are the body's attempt to provide a solution to this stress.

For example, someone who believes violence is wrong yet experiences an urge to react violently to a traumatic situation may experience numbness in their arms or legs as a way of suppressing the urge to hit or kick.

However, some people may develop FND even in the absence of stress or depression.

Some studies have shown that people with FND have decreased functional connectivity in certain parts of their brains, including those parts that control the muscles and senses. This indicates the body's lack of control over physical movement or actions.

Can't say I have heard of this.
