Hi Lildreamer.
I would bring this up with your doctor. Due to the fact you are still on very high doses of prednisone, and the cyclophosphamide, I would be careful. You are now immunosuppressed, and even minor chances of infection can have major implications. You may be better off waiting until you can lower your meds and stabilize a little more.
God Bless and Keep Up The Good fight.
