I am 55 y/o andwas diagnosed with mild osteopenia and lumbar instability. Is it safe for me to take caltrate or calcium carbonate supplement coz I was told that taking that will cause kidney stone. When i drink milk i get stomach upset. What can I do to improve my bone density. Last year, when I made sudden movement, my whole body suddenly got paralyzed and sudden movement caused a lot of pain, i just couldn't move without experiencing excruciating pain for 3 days.I took meloxima and gradulally improved.i am now extra careful in lifting objects so as not to experienced such pain. Should i have my bone scan to determine how brittle my bone is? Pls. Advice me and many thanks
