I'd like to hear the answer, too. I started running just to counteract the trend, which ended up just starting some pretty awful back/hip issues. I am ignoring it so far, with the possibility that it is a disc issue (been to the doc once and first line of treatment didn't do a thing). I stopped running, even though I liked it, because a lot of the research I read said running might actually cause fractures. Oy, not sure what to believe. I had the passing thought my back/hip pain might be a fracture, but it comes and goes and when I described it to the doc, he pretty much confirmed my description by immediately stating, "it's a disc." Next step is MRI, but I am waiting to get the osteo stuff straightened out.
Like you, Deb, it's worse in my spine than hips and still at the mild stage. I had a slow speed crash last summer, with no ill effects.
