I took my first Reclast infusion in November 2025 felt like I had the flu for about 3 days. Approximately a week later I started have the most intense femur pain. I could barely walk. I had a total hip replacement about 12 years ago at the age of 40. I saw my orthopedist because I was out of my mind with pain. Come to find out I had a huge bone growth at the end of my implant which he believes is causing my issue. He had said he could change out my. Prosthesis which would entail windowing open my femur and chiseling out the implant and doing a cage to repair the femur. This sounds horrible but I’ve been in such pain what do you do? I hate pain medicine but the surgery sounds horrible. Sure wish I knew what I know now about Reclast. I wonder what percentage of patients have this horrible side effect?
