I have osteoarthritis of the back and arthritis of tons of joints, is this related to fibromyalgia?

No. Fibromyalgia is thought to be caused by a neurochemical deficit in the brain (low brain chemicals). This manifests itself as muscle pains but is in fact caused by low levels of brain transmitters. Osteoarthritis occurs within the joints as a result of inflammation.
No. Osteoarthritis is a structural disease of worn joints, cartilage loss, and bone spur formation. Fibromyalgia is a chronic painful condition in which pain is felt in normal structures.
