I am so sorry to read of all you have gone thru, KathyMac!!! You've really had a rough road to hoe!
The general consensus is that a bisphosphonate is needed after the two years of Forteo to maintain the good that Forteo was able to do. It is too bad you had to spend so much inactive time whilst you were on the Forteo and that might well be why you didn't see improvement w/the Forteo. There is always the option of IV bisphosphonate rather than the oral.
If I remember right, Evista (hormone therapy made by Eli Lilly) has had some good success w/osteoporosis w/and w/o Forteo.
By all means, see an Endocrinologist. And given the problems you've had an Endo at Hopkins sounds like an EXCELLENT idea!
You can help yourself just by doing some theraband stretches and then some very light weight hand weights. I wouldn't try ankle weights until and unless you feel good and steady on your feet. See if your local hospital offers exercise/rehab sessions for osteoporosis. You want to be doing the right exercises for your hip and spine and osteoporosis, not aggravating the situation.
Good luck and God bless!!!!
