I understand and I appreciate your concern. I have turned to Reclast to prevent abrupt loss of bone density and resulting fractures. I made sure that I started the Reclast right when I was due to get my second Prolia injection. It is my hope that I can prevent any negative effects from stopping the Prolia with only one year of Reclast. I hope the very sore arm muscle pain I have with Reclast will fade with time.
