osteoporosis
"I had my first Reclast I.V. injection last winter, just prior to the holidays.  I had about 5 days of severe flu symptoms and seriously considered not repeating the injection the next year.  However my bone scan was so positive and even with several falls I have not broken anything.  
Prior to the Reclast I had, in 2 years, a fractured hip, wrist and ankle.  Surgery on the hip showed a femur like Swiss cheese and the severe fall seriously impacted my life.
This year I'm 70 and preparing for my second IV, seeing a dentist to make sure I don't have any serious issues that need to be dealt with.
I also quit taking steroid spinal IVs for chronic this year thinking I could deal with the pain and perhaps not have further breaks. I endorse Reclast."
