I had Reclast infusion about 2 years ago. They told me you will probably feel some mild pain in the next 3 days, which I expected. However, ten days after the infusion, I awoke to severe all over pain where I could not move out of my bed. Called my endocrinologist and she claimed she never heard of this but she ordered out a prescription for 100 mg of Tramadol. It took a week to get some relief from that high level of pain in every joint! It was like a poison infusion to me and I will never, ever have that infusion again. Now that I’m reading others reaction to it, I know it’s not a good thing for people to have.
