Oh Kass, poor baby! I had exactly the same thing a few years ago, from burning brush to which someone had added fresh poison ivy, without my knowledge. It took two courses of prednisone to clear it up; don't be surprised if it takes you that long. For faster-acting relief, I used a product called Zanfel that you can buy in the drug store -- it's pretty expensive, like about $35, but it really, really works. I can't recommend it highly enough. Sometimes you have to ask the pharmacist for it because it has a tendency to walk off the shelves all by itself at this time of year, if you get my drift.

Sending you all kinds of comforting energy.
