Thanks for the information. I truly believe that the Reclast infusion activated a flare up of my fibromyalgia, as well as the body parts that I have osteoarthritis. My concern is that it’s been 3 weeks and the pain has increased. When I was given the infusion it took 45 minutes and they also gave me IV fluid. I’ll be happy when the pain subsides and I could exercise. Again, thank you for responding. It makes me feel that I am not the only one with pain from the infusion.
