I'm sorry you've been undergoing so much, Ally.
I was diagnosed with Fibro at the same time I received my official CFS diagnosis. Some years later I went on to see Dr. Wood, a well known rheumatologist and researcher specializing in Fibro, in fact from what I heard he only sees fibro patients. His gentle examination left me in agony.
My experience has been always in pain, pressure makes it worse (even the pressure of laying on one side for too long, and the pain wake me up) and some days are worse than others. At times I had weeks on end where my pain never drops below a 7 on the scale of 1-10. I ended up resorting to narcotics for the nights when the pain was so severe that I'd otherwise spend hours yelling and moaning, unable to even sit let alone lay down for the increase in pain. It was several years before I had effective pain management through drugs, which enhanced my quality of life dramatically.
Learning meditative techniques that bring down my nervous system from a sympathetic state made a massive difference - I was no longer compelled to take the drugs, and within two months of learning it I was experiencing windows within which I wasn't in any pain at all. Oh, that was such a victory for me!
Cranial osteopathy identifies and addresses the root of my pain, which is areas where nerves are compressed, bloodflow is compromised, etc, and within 3 months of treatment it was becoming rare for me to experience any pain at all. My osteo can feel with his hands where there are structural issues affecting nerves and can relieve it. I have never experienced pain from my osteo (DO)'s touch, but I have from many massage therapists, chiropractors, etc so I'd recommend getting a very experienced one if you do go that route.
I now rarely have a day or two where pain is at a 1-2. Though there are a few non-fibro sources of pain, I've been mostly pain-free for about 6 months and I do not believe I would currently match the criteria for Fibromyalgia.
Hope that helps.
