You are young at 63. Prolia has its use in older patients who may need it for a lifetime. Prolia is very very difficult to get off of safely without traumatic fractures and its long term effect ( 20 yrs ) are unknown. I am not a scientist - but from all I have been told, it is dangerous drug.
Educate yourself as best you can - find out how to get off PRolia if you need to. YOu must be comfortable with the course of your treatment. Meanwhile Reclast is also very very strong...and has a long half life in the body. Do you need anything that strong???

I too have seen HSS in NYC - My doc at HSS would never give it to me at my age and I am 69. Now be aware HSS is research and evidence based - osteoporsis on the onther hand is a very individual case . In my opinion you need to be evaluated as an individual ( not how a 'group' of people responded) and find out the cause of your condition. Has HSS determined the cause ? HSS did a superficial job with labs - checked the basic VitD,PTH,wheat allergy phosphouse etc. THey did not test bone markers ( bone markers are critically important to moniter therapy) You have very complex issues going on and were very fit like me.
DId you have bone markers done? ( P1NP and CTX) I recommend a full lab evaluation with bone markers - check inflamamation, gi , and many other contributing factors. In my case there was no inflamation but high homocysteine, protein deficincny,high b6, high bilirubin and indications that there are genetic factors involved. - I had to work with an informed caring primary care and local docs. I have been disabled for almost 2 years and am determind to heal and teach and live again. I greatly recommend the book Great Bones by DR Keith McCOrmick - it is a bit scientific but stay with it and it will help your understand and guide your way.
Lastly if you have your bone marker history, your doc will have clear information about when to take you off FOrteo - some people come off 16 ot 18 moths, some can stay on it. Depends on bone markers - are you still building bone in relationship to the dismantling of bone??? There is no magic number to watch for; it is the porpostion of building/vs/ dismantiling based on your history. I myslef will recheck bone markers at 18 months of tymlos - if my building markers have pulmetted then I need to get off the medicance and onto something to help seal in the gains.
Sendign postive energy for you to find an caring and informed path to support and restore your health.
