I had a reclast infusion in May of 2023. I will never have another one. I had very bad flu like symptoms at first. Achy bones, fever, you name it. But, within 2 weeks of the infusion, my quality of life took a nose dive! I needed to be cleared to make sure it was OK to have back surgery for spinal stenosis. I've always been healthy and strong. Not any more! Please, please, research this drug.
