I know I'm going to sound like a broken record, but a vitamin D deficiency can lead to all sorts of back pain. I'm the poster child for that. The difference in my back after starting vitamin D supplements is miraculous.

And an except:
However, Plotnikoff published a study in 2003 on 150 people in Minneapolis who came to a community health clinic complaining of chronic pain. Virtually all of them -- 93% -- had extremely low vitamin D levels.
Vitamin D blood levels of 30-40 ng/mL are considered ideal. The average level in Plotnikoff’s study was about 12, and some people had vitamin D levels so low they were undetectable.
“The group with the lowest levels of vitamin D were white women of childbearing age,” Plotnikoff says. “Most of them were dismissed by their doctors as depressed or whiners. They attributed their pain to an inability to manage stress. But after we replenished their vitamin D, these people said, ‘Woo hoo! I’ve got my life back!’”
Plotnikoff notes that vitamin D is a hormone. "Every tissue in our bodies has [vitamin] D receptors, including all bones, muscles, immune cells, and brain cells," he says.
And in March 2009, researchers at the Mayo Clinic published a study showing that patients with inadequate vitamin D levels who were taking narcotic pain drugs required nearly twice as much medication to control their pain as did patients with adequate D levels
I was turned onto the miracle of Vitamin D supplements by a customer that happens to be an ER physician. He noticed me favoring my back and sat me down at my PC and started showing me all the research. It was winter, so he knew I wasn't spending lots of time outside. I told him (he asked) if I drink milk (answer: not really, coffee, water, soda). So he told me to take vitamin D supplements and within months the difference was remarkable.
