I had a Reclast infusion February 2023. It laid me out for about 7 months and I am still having side effects. The first 3 weeks were a nightmare with horrible bone pain everywhere in my body. So painful I could not sleep. After the bone pain started subsiding the other side affects remained (tired, couldn't sleep, swelling in hands and feet, muscle spasms, chills, rash(small clustered blisters) and the first week after the infusion I gained 10 lbs. I will NEVER have Reclast again. I was on Prolia for several years before Reclast-just had a constant headache with that one. I don't think my body will every feel the same again due to Reclast.
