I totally 'get it'. I had broken ribs sneezing, broken clavicle reaching for the phone...The shock....at 35 I fractured my T9 playing volleyball on July 4th. Really I was only raising my arms above my head. After multiple weeks of therapy and little relief of pain and back spasms I saw a spine specialist. He took an X-ray (1st one) and I found out about the fracture (Sept 10). I had my initial DEXA scan with -2.9 spine and -4.7 hips. Premenopausal and no history of osteoporosis. Started on Fosamax daily...worked for a while then tapered off...then 2 years of Forteo (worked wonderfully and wished I could have remained on that for longer but not suggested), then Fosamax weekly....At this time I was diagnosed with Systemic Mastocytosis because of the severe numbers on my scans and spots on skin. I was sent to Mayo and saw 3 doctors, many tests and a bone marrow biopsy (having extra mast cells in bones)...causing more brittleness. My osteoporosis specialist at home gave me a 'drug holiday' since I'd been on medication for so long and at a younger age. Plus with the diagnosis at Mayo...I ended up with chemo (Interferon) 3 x a week for 3 years. Then 2 years ago I slipped and broke my pelvis in 5 spots and was told no surgery since I have 90 year old bones. So after 11 weeks began Prolia. I am on the end of my 2nd year. Really was the only thing left for me to use. Hasn't worked as well as Forteo...but could be age as I'm now 60. I have had NO side effects from any of the medications.
