I have been on steroids for two weeks, both internal and topical. I still itch extremely bad. I haven't had a nights sleep since i got the ivy. Now the bumps are reappearing. The itching is not only in the area of reappearance but has been constant under the arms, on the belly and inner thighs as well as on my neck, all of which have no bumps or blisters. Does anyone really know what is going on with this stuff physiologically. It sure seems systemic to me.
