Rash is coming back :(

I cant sleep, my ankles hurt so bad!!! It's 1:30 am and I have to be up at 7:00!!! This rash on my hand is coming back and Im trying so hard not to scratch it. The skin just breaks open anyway. I use to think that the skin would break open because of me scratching but either way it happens. Does anyone else here get a rash that always returns in the same place? The only thing that helps is prednisone but Im off of it right now. Does anyone have any suggestions? I really wish I could just fall asleep.
