What else can I try for poison oak?

Debora asked...

I was diagnosed with poison oak over a month ago and was given some prescribed Benadryl and some trivolone ointment for my rash. (something spelled like that). Well none of that worked, so I went back to the doctor and got some prednisone (6 pills, 1 whole pill for 3 days and then 1/2 pill for 6 days) and some Lubriderm lotion with kenalog and my condition seem to be getting better except after I was off the prednisone my itching returned 10x worse, so now my hands, palms, and arms looks horrible and this is embarrassing. I have broke out in my brown spots and you can actually feel all over my hands and palms, I mean approximately 6-7 spots on each finger - big noticeable spots that you can feel! My arms have sores. Needless to say, I am in a bigger mess than when it started over month ago, What can this be? I don't have private health insurance so I will be going to the hospital district for treatment, which I am thankful for them. Is there anything you can tell me about this? I went on an interview, but of course I would not hire me either. Please help!
