I can't answer your question but I like to blame Predisone for everything, you might want to read the paperwork that comes with you Predisone to see if the rash is a listed reaction to the devil drug.
the first couple of months of taking Humira I definitely was itching a lot more than normal, that was to be expected because it is a know side-effect of Humira, it has since gone away as my body has adjusted to it.
