I have just had my fourth injection of Denusab (is that how you spell it?) for my ostioperosis. I have since taking this been having a great deal of muscular pain in my legs. I see from reading the pros and cons that this can happen when taking this medicine. Does this pain go off or am I to put up with this on a permanent basis? It is quite debilitating especially as I have two dogs who need walking, which I find extremely uncomfortable and quite painful.
