Denusomab and back pain

I have mets in T9.  Last PET in beginning of March shows remission.  However hadDenusomab injection end of March and I am experiencing my back being very tired and achey, do any of you relate?  

Hi there, I also get joint and bone pain a day or two after my denosumab injection, I tell myself that’s it penetrating the damage! A couple of solpadeine is usually enough to solve the pain xx
