Has your PTH levels been checked? I'm assuming that your doc has done that, but just thoughtI'd ask, since my first doc didn't order that test. I had parathyroid tumor, which caused low absorption of calcium, and hence my osteoporosis. After the removal of the tumor, I tried a year of exercise (mostly treadmill). My spine got better, my hip stayed the same, and my femoral neck got worse. Your situation is different, tho; my osteoporosis was severe. Don't want to discourage you. Also, I think generally it takes two years to see a difference. Others can weigh in on this.
