i was wondering if anyone has experienced mid to upper back pain after taking Prolia or Xgeva? I don't mean the acute pain that you get after the shot for a few days but rather chronic back pain and back fatigue. It dawned on me the other day that at the end of the 6 month interval right before i am due for another shot and the Prolia is wearing off, that my back pain is much improved. So wondering if all this back pain is being caused from Prolia. I have been on it far too long...7 years and would stop tomorrow except for the pesky rebound effect which no one really seems to know how to manage.
