If it were true that the fibro pain is just caused by anxiety and tense muscles, then why do so many of us feel horribly stiff, tight, and in pain first thing in the morning after we have "relaxed" all night? (not directed at you, Sue - just kind of rhetorical )
I've heard so many "causes" for fibro that I'm skeptical of them all. I've even had two rheumies in the same practice tell me two different things. One said that it was solely a sleep disorder. The other said that it was purely a central nervous system pain interpretation problem and that we interpret pain that should be a "2" as a "10". Then you have the micro-bacteria, virus, and trauma theories (and many more I've heard of over the years).
I guess I have little "alarm bells" that go off when a doctor says that fibro is caused by anxiety. It's too close to the "It's all in your head" school of thought. I believe that anxiety makes fibro worse, and I know that many people with chronic illnesses develop anxiety and depression, but I'm not so sure I'm on board with the fibro is caused by anxiety theory.
I'm really glad that you posted this, Sue because it opens up a lot of good dialogue, and it helps us see what ideas are floating around out there. I'm thrilled that there is so much new research going on and very, very hopeful that eventually the cause (or causes) will be definitively determined so a cure can be found.
