I hope you feel better by now !!! It is certain that we all react differently to these biphosphonates and prolia. I had an infusion of Reclast one year ago after one year of Prolia. I do not intend to get any more biphosphonates or Prolia. My muscles and joints are very painful. My doctors insist that the pain I have is from arthritis. Does anyone know how long Reclast stays in the body? Who is the best doctor to treat arthritis ? I have been to a endocrinologist, and a rheumatologist and they just tell me to do physical therapy. I need one central doctor who will help me manage my arthritis. My primary doctor also says to do physical therapy. I have been through three series of PT /three times a week, without any positive results. It is difficult to do the "Core strengthening exercisis" because I have a prolapsed uterus and bladder. Meanwhile, the pain continues and I rely on tylenol to help. Thank you
