I'm scared i may have fibromyalgia. i have severe back pain where i can't get out of bed. i always feel tired and no one knows why. what could this be?

Many problems cause : Fibromyalgia causes symptoms of muscular pain, fatigue and disturbed sleep. It is not associated with hot, red or swollen joints, which are more indicative of an arthritic condition. Muscle overuse, thyroid problems, diabetes and other health issues can play a role. In latitudes like the pacific north west, vitamin d deficiency is a common cause of these symptoms, but it can occur anywhere.
