@gentlyThe side effects of osteoporosis are horrid, but I had no choice. You have to "pick your poison" when you choose one of these drugs! I will say that Forteo made a huge difference in my spine. I have DDD and need lumbar surgery. I wouldn't have been able to have the surgery without the improvement provided by two years of Forteo injections. I am now on Evenity. My second infusion produced huge welts at the injection site, but no other reactions. I will have to use Prolia or Reclast after Evenity is done. I am fearful of both of them. Reclast is hard on the kidneys and osteonecrosis of the jaw bone is always a risk.
