I would suggest tapering off the prednisone ASAP. The last two years I suffered with UP (proctitis), I had become prednisone dependent. I had surgery June 28,2010 and was able to finally taper off the prednisone by the beginning of that August.
Please, PLEASE make sure you take calcium with D daily. Even doing that, prednisone gave me full blown osteoporosis. While on it, I suffered with uncontrollable high blood pressure and type 2 diabetes. Thank GOD I no longer suffer with those two maladies. Having 3 back fractures and now an arthritic hip is bad enough.
