Fibromyalgia is simply not a medical condition. I don't believe it to be a psychiatric problem either, although it is obviously linked to mood disorders.
Instead, it is probably best classified as a choice to be miserable. Or, as part of the human condition should a human being become exposed to lack of excercise, sleep, and fulfillment in life with additional use of tobacco, processed food, extra calories, self pity, and stress. Doctors no longer classify homosexuals as having a medical condition. Nor left handers.
FM ought not be a medical condition either and it is unfortunate that it is - because nothing within medicine helps them, anymore than it would 'help' a left hander. It is best handled by psychiatry to address the possible underlying depression and by counselors - for those few patients with the bravery to recognize their problem for what it is and stop seeking magic pills/shots/fairy dust to immediatly cure their 'condition' without addressing the myraid of underlying problems, thus enabling them to continue their unsustainable lives.
Seriously, most humans were not born to never excercise, sit around constantly getting fat, smoke, watch non-stop TV, and have poor sleep habits.
