gaylea, My heart hurts for you.

I had that severe itching, too. It was so awful that I was often on the verge of tears. There was not a doorway that was safe from my constant back scratching. Imagine the image of a big ole grizzly rubbing against a tree - That was me!
Sometimes a good soaking bath with Aveeno oatmeal bath oil helped briefly, but even that brief escape from itching was not worth the trouble to me, because it was an overwhelming task. I was fatigued, and my edema made movement difficult, and I was cold all the time. I never got to where I was scratching until it bled, though, I hear that that can happen.

Somewhere along the wait, the severe itch gradually diminished. I don't know why.
We are all different in our symptoms as we await our transplants.

Hugs to you and to anybody who is also experiencing these symptoms.
