The pain started in my lower back now down my legs and hips and now to my shoulder and ankle, what could it be?

Fibromyalgia. The defining characteristic is whether the pain is strictly in joints or is it in the meat of the major muscles of the lower back, legs and shoulders. Pain in muscles and with muscle use suggests fibromyalgia. Pain in the joints suggests a rheumatologic problem. Lyme disease, lupus, and immunological disorders complicate the diagnosis. See a rheumatologist for proper diagnosis & treatment.
