Well Megan,
My humble opinion is that it is not too important to be diagnosed but to be helped... at least in cases like fibro...
My doc actually never mention names, I mean, of the illness... He is too funny. Love him. My mom has diabetes, and he was like "call it like you want but you have high sugar levels and you have to take this, do this etc..."
He never mentioned me fibro or osteoarthritis but, he gave me lyrica, celebrex, b complex, zinc, etc...
So, yeah... I dont care much about the name, but the treatment doctors give so...
Just my humble opinion.
Are you taking anything for your aches ?
