Hi Becky, Sorry to hear your T-scores got worse on the drug. That , too, is a bummer. I've been on prednisone since mid-May so maybe it's too early for it to have thinned my bones, But I had the autoimmune disorder (PMR +GCA, later) a year before diagnosis. For the last year, after my walk in the morning, all I could do was collapse on the couch because of the pain. So far, the prednisone as has been good to me, as good as it can be, I guess. I'll know more as I continue to taper. There is a family history of osteoporosis and also the PMR + GCA, my aunt had it too. And my mother-in-law, believe it or not. I hope the Cell Cept works for you.. It would be nice to hear if anyone was able to get better bone density through medications and exercise while staying on steroids.
