Interesting that Prolia didn't work.
Interactive doctors are the best.
You have a while to determine which medication to take next because you can't get Reclast out of your system. You're good for a year or two provided Reclast is working. That pain level is extreme, but there are published case report of patients being hospitalized after the infusion. I hope the pain is improving, if it hasn't sufficiently by Monday, you might best ask for steroid. The speculation is that the initial cytokine reaction can be self sustaining without regard to the medication. Steroids aren't fun and they aren't good for the bones. I've read that a five day isn't bad for the bones the way long term inflammation is.
Your provider probably would have told you if they'd known. It's surprising how many prescribers tell their patients that the side effect isn't because of the medication.
