@stephenbrown Hi Stephen. I too have had cramps in my hands, legs and feet since my transplant but not nearly as bad as yours. They are there but not bad enough to bring it up to Mayo or local docs. But I think for me it may be do to me no longer having a galbladder due to the transplant .
And resulting from that water / liquids passing through me more quickly and me not staying sufficiently hydrated. Just a guess on my similar issue. Hoping it gets better when your off the prednisone for a while. Best of luck . (--:
