I have noticed that my the bones in my back (upper or lower) get out place easily where I go visit to the chiropractor at least once a month. Is this a risk factor for osteoporosis or arthritits, or simply normal? I had a abnormal screening saying I had osteopenia by a bone density meter from a health fair (measured from the ankle/heel so it wasn't a dexa) but this is not accurate. I told the doctor about the abnormal screening and I have the order for a dexa but I just would like to hear your input. I don't want to panic about it, i just curious of whether my back problem might be linked to osteopenia.
