tiny28,
I would suggest Forteo or Tymlos, mainly because of the way they work building integrated bone. But also because they leave your system quickly, if you were to have an unexpected adverse reaction.
For my SI joint I see chiropractors with success. Be sure they know that you have osteoporosis, so that they can perform gentle adjustments. I'm sold on chiropractors because they understand body mechanics so they can advise against the types of movements that throw your SI joint off, and recommend gentle exercises to keep the joint moving correctly. I even watch the youtube videos, but have never been able to self adjust.
