Hi Grailhunter,
I can help you with this question! Fibomites have high cortisol levels, respectively. The HPA axis (and I'm so glad you're familiar with it), is the root of our pain and high cortisol levels.
The Hypothalmus and Pituitary gland send wacky signals to the Adrenal glands. The adrenals then send out way too much cortisol. It's a vicious circle that can't be rectified. That's why we seem to have anxiety issues, depression, fast heart rates, sweating, etc. All that cortisol!
That's why you felt like you were going to explode when taking anti-Ds. It's also why taking prednisone or anti inflammatories make us feel worse. We already have enough natural anti inflammatories in our blood system - this being the cortisol. When you add even more cortisol - the synthetic kind, the result is an overload. Pain and stimulation of the peripheral nervous system is what we end up feeling.
Researchers don't know why the HPA axis messes up. But it has become very clear that this is where our problems are stemming from. Now they just have to figure out the rest of the puzzle!
I have to take prednisone for my lupus or I'll die (to put it plainly!). It's a catch 22 because the more pred I'm on the worse it makes my Fibro. So it's a very delicate balancing act.
So that's my schpeel! I'm interested to hear what you think of this. I learned all this HPA axis stuff in a 2008 edition of "Fibromyalgia and Chronic Myofascial Pain Syndrome - A Survival Guide". Written by doctors. All very legit. Super interesting actually.
