Not rescan. Re-read. If your report has a TBS score, you could also take a look and see if it had improved. Mine improved to lower end of normal range which at the time gave me some assurance.

Not sure about tymlos (I've read a lot about forteo), forteo is known to cause porosity in cortical bones and reduce femur neck's bmd a bit, but this effect plus the slight effect in bone structure increase (I forgot the technical term) may actually maintain or increase the strength of cortical bone, it was postulated.
