Less likely-osteopor: People with RA are prone for osteoporosis earlier. It is less likely at your age to have it. Two things you can do. 1. Get blood vitamin level measured 2. Get a DEXA scan of bone which will bring out the osteoporosis. In the bone scan if you have osteopenia(decreased mineralization with calcium or osteoporosis with sparse mineralization of bones ,you need bisphonates-a different gp of medication
