I didn't go to the hospital but I was sure sick with pain. I had Reclast Feb. 28 and I am still have bouts of severe bone pain. They come and go. I will never have it again. The doctor told me after 3 infusions (that is 3 years) I would be good for 10 years. Well, I am 75 and I am not willing to give up 3 years of living for 10 years---by that time I will be 88! Gees!
